Further unlocking the potential of maize: Dual-purpose is the new purpose of the world’s most important cereal

A September 2013 special issue of the scientific journal Field Crops Research describes research to improve, and make wider use of, dual-purpose maize (or corn) varieties, which are used for their stover — the stalk, leaves and other residue of the plant after the grain has been harvested — as well as for their grain. Among smallholder farmers in Africa and other developing regions, maize stover is a common, and critically important, supplementary feed for ruminant livestock.

The special journal issue was edited by edited by Elaine Grings, of South Dakota State University (and formerly of ILRI); Olaf Erenstein, of the International Maize and Wheat Improvement Center; and Michael Blümmel, of the International Livestock Research Institute (ILRI).

The following statements are excerpted from a synthesis paper written by the editors, which presents key ﬁndings in 12 papers about the potential for dual-purpose maize varieties to meet changing maize demands.

This special issue substantiates that dual-purpose maize varieties are technically feasible and have a large potential market, particularly in many emerging markets. The reported ﬁndings argue the case for continued investments in maize stover R&D and thus reigniting earlier dual-purpose crop research in general.

Among the findings are the following.

‘Maize — or corn (Zea mays L.) — now is the most important global cereal in terms of production reﬂecting its versatility in use, including human food, animal feed and fodder, industrial products and biofuel.’

‘Despite being a versatile crop, maize production and maize breeding efforts over time have typically had a single-purpose orientation [on improving grain yields]. . . . Even smallholders within mixed maize-livestock systems typically focus on maize grain yield . . . , with maize stover as additional byproduct and beneﬁt.’

There are prospects within the range of stover quality to increase fodder quality without compromising grain yield.

‘It is this potential of dual-purpose varieties that has reignited research interest and some of the research underlying this special issue. Indeed, despite earlier skepticism only a decade ago, substantial progress has been made in developing dual-purpose maize options for both grain and fodder purposes . . . .’

‘Maize germplasm differences in fodder quality can be exploited without compromising on grain yield.’

‘Conﬁrmation of the relatively favorable feed value of maize stover vis-à-vis other coarse cereal residues — having at least par if not better feed quality traits compared to sorghum and millet, which have been the focus of prior dual-purpose crop improvement research and have been reported to contribute substantially to gross crop production values.’

‘Conﬁrmation of being able to rely on a few key laboratory indicators . . . as good proxies for feed quality . . . as this enhances the ease of screening for feed quality traits.’

‘From a livestock nutrition viewpoint, an increase in stover quantity is only useful (unless making stover cheaper) if livestock can respond with increased intake, which is stover quality dependent.’

Tarawali had three main messages for her audience, for which she and her colleagues provided samples of latest research work at ILRI and its partners around the world.

Don’t decouple crop intensification efforts from livestock intensification work.
Address the biomass challenge.
Improve the efficiencies of smallholder livestock production systems to reduce any harm they cause to the environment.

(1) DON’T DE-COUPLE CROP AND LIVESTOCK INTENSIFICATION

Mixed crop-and-livestock farming systems are important for feeding the world

Smallholder livestock keepers in developing countries are remarkably competitive

Livestock benefit crop production

Crop production benefits livestock

(2) ADDRESS THE BIOMASS CHALLENGE

(3) IMPROVE SMALLHOLDER LIVESTOCK PRODUCTION EFFICIENCIES TO REDUCE ENVIRONMENTAL HARM

Taking stock: East Africa Dairy Development project reflects on its achievements and lessons learned

Posted on July 2, 2013 by Tezira Lore

From 2008, the East Africa Dairy Development (EADD) project has been working in Kenya, Rwanda and Uganda with the aim of transforming the lives of 179,000 families (about 1 million people) by doubling household dairy income in 10 years through integrated interventions in dairy production, market access and knowledge application.

The project is funded by the Bill & Melinda Gates Foundation and implemented by Heifer International, African Breeders Services—Total Cattle Management, the International Livestock Research Institute (ILRI), TechnoServe and the World Agroforestry Centre.

With the first phase of the project ending in June 2013, two members of the project team—Isabelle Baltenweck, agricultural economist at ILRI, and Gerald Mutinda, the EADD regional manager in charge of dairy productivity, gender and youth—recently had the opportunity to take stock of some of the project’s key achievements during a ‘livestock live talk’ held 26 Jun 2013 at ILRI’s Nairobi campus.

Livestock live talk is a seminar series at ILRI that aims to address livestock-related issues, mobilize external as well as in-house expertise and audiences and engage the livestock community around interdisciplinary conversations that ask hard questions and seek to refine current research concepts and practices.

The talk began with a description of the project, its value chain approach, vision and objectives, and followed by an overview of its achievements and lessons learned.

The speakers then highlighted the project’s innovative ‘hub approach’ which was adopted to help overcome the challenges small-scale dairy farmers often face in accessing farm inputs such as feeds as well as animal breeding and health services.

The hub approach takes advantages of economies of scale and enables service providers to have a wider customer base, thereby making it more efficient for them to operate. Through the hub approach, farmers organize themselves into dairy farmer business associations that make it easier for individual farmers to access inputs and services as well as facilities for bulking and cooling of raw milk.

It was noted that the hubs should not be viewed as a ‘model’ per se, but rather as an approach that can be tailored and adapted to suit different regions and countries. For example, the project found that many hubs can be successful by providing milk bulking services alone while others can offer both milk bulking and cooling. For the second phase of the project, the hub approach planned for Tanzania is centred around the provision of inputs and services.

Another key learning point was the importance of ensuring that the due attention is given to gender aspects during the design and implementation of the project. The speakers admitted that key aspect was overlooked during the design of the first phase of the project. As a result, some key gender-based indicators were not properly tracked.

However, this oversight has been corrected and the team now has a comprehensive gender strategy in place to guide the project design for the second phase to ensure that gender mainstreaming is incorporated through gender analysis at various levels of the value chain as well as monitoring and evaluation of thematic gender-based studies.

In 2012, a group of researchers at the International Livestock Research Institute (ILRI) worked with partners at the World Bank, under the direction of Jimmy Smith, then a senior livestock advisor at the Bank and now director general of ILRI, in identifying investment opportunities for ruminant livestock feeding in developing countries.

Excerpts from the executive summary follow.

‘Driven by population growth, increasing demand, stricter quality and safety standards for animal source food and increasing competition for land and water resources, the livestock sector is changing rapidly. Within this changing landscape, smallholders with crops and livestock will remain the mainstay of the sector in developing countries for some decades to come.

For example, the projections in this report foresee an increase in cattle, sheep and goat populations in the mixed crop-livestock systems in the developing world from 467 million to 648 million adult cattle equivalents. However, also here, the abovementioned mega-trends and the resulting competition for feed resources imply that these systems will have to intensify to ensure an acceptable livelihood for its producers.

‘Enhancing the quality and quantity of feed, as one of the most important factors of animal production will play a critical role in this process of intensification. However, feed improvement should not be seen in isolation, but rather be assessed as part of the greater value chain, including all stakeholders. For example, investing in feed improvement without markets to sell the increased production from this investment or without an adequate feed quality control regulatory framework, would yield negative returns.

This report follows a step-by-step analytical framework that will provide the priority investments and actions in technologies, policies, and institutions.

‘As the first step in this framework, the most promising value chains, where feed-related strategies and investments are most likely to have significant impacts, have to be identified. On the basis of the key characteristics of (a) growth and market opportunities, (b) number of poor and pro-poor potential and (c) the supply constraints, in particular disease risk and feed resources availability, this report identifies first Sub-Saharan Africa and South Asia as priority areas, and then, within these areas, it identifies three commodity value chains in five regions of particularly great potential to benefit poor producers and consumers. They are:

Dairy in East Africa and South Asia
because of the expected growth in demand (including export potential), the number of poor involved (135 million), and the moderately adequate situation resource situation
Beef in West Africa
because of its potential for import substitution and potential for improvement, in spite of the resource constraints
Small ruminant meat in West Africa and Southern Africa
because of the number of poor involved (110 million) and new domestic market opportunities.

‘The framework was then used to analyze the diversity of feed types, the availability of feed sources both from within and from outside of local systems, based on informant interviews and quantitative modeling of the current situation and with projections to 2030. Detailed data for each feed type and source are available in the main text, but the general trends show:

(a) A reduction in the use of crop residue
such as straws and stovers, although at a projected between 20 and 50 percent these remain a substantial part of the daily ration of the livestock of those systems.
(b) An increase in the use of crop-by-products
(such as oil cakes and by-products of the milling industry) and concentrates, although staying in 2030 mostly below ten percent, with the exception of the South Asian dairy systems, where they would amount to 25 percent of the total diet. With such a low share of the diet, and with most products not edible for humans, these systems would not endanger global food security.
(c) An increase in the area planted for forages,
in particular in dairy systems; and (d) a sharp increase in feed procurement from the market instead of supply from the own farm.

‘Based on these projections to 2030, opportunities for feed-related investments with major positive impacts on the poor are then identified. A number of strategies, policies, technologies, and services come to light as especially promising areas for such investment in a variety of scenarios. Applying the assessment framework to each of the three value chains yielded similar results for all chains. First of all, they stress that addressing feed related issues in the context of evolving value chains requires combinations of public and private investments: policies, strategies that facilitate adoption and market engagement with reduced transactions costs such as improved access to knowledge and services for smallholder producers and other market agents together with adoption of improved feed technologies.

‘The more specific areas of improvement that warrant priority in targeting investments are:

Technological feed improving solutions include in all value chains studied
(a) more attention to research and development for feed/food crops, i.e., crops that provide both food (mostly grain) for humans and feed (mostly straws) for livestock;
(b) better ration formulation, through the introduction of feed processing and storage technologies (including micro-sizing, ensiling, etc.) and
(c) forage seed production. . .
Institutional issues include access to land and water for all smallholders, as a primary concern and as the main incentive to improve crop-residues. Effective governance on feed quality is also a common institutional issue raised. Similarly, reduction on transaction costs (both to access the feeds and to participate in product markets) is another key area for institutional investment support. In all value chains, the report strongly advocates support to Business Development Services – interpreted in the broadest sense as a key to facilitating access to feeds, markets and for reducing transaction costs. . . .
The policy concerns are more value chain specific, and include the protection against dumping of meat and milk from the OECD countries, reduction of regional tariff barriers (in particular in Sub-Saharan Africa) and lack of investment in infrastructure.

‘While for many households increasing animal numbers is perceived as attractive, there are severe environmental limitations of the extent this is possible. Policies and investment that increase per animal productivity, such as adequate ration formulation and emphasis on mineral supplementation in the feed and nutrition domain, as well as genetic and health improvement related investment will be important. However, in some areas, increased efficiency (producing the same with fewer animals, or more with the same number of animals) can also be achieved through incentive systems such as payment for environmental services.

‘Ranking those investments regarding their economic return constitutes the final step in the analytical framework, underpinning this study. The analysis shows that for an individual household, the increase in animal numbers is the most attractive option, as has also been proven in the past.

Indeed, according to FAOSTAT (2010) data, most (57 percent over the period 1990–2010) of the increased production in Sub-Saharan Africa comes from an increase in animals, and not from increased productivity per animals. This is obviously not sustainable.

‘The key challenge therefore is to increase the profitability of raising productivity per animal. As better feed utilization will be a critical factor in enhancing the profitability and hence in ensuring the long term sustainability of these system, it is therefore encouraging that in most evaluations feed improvements (and in particular the use of crop-residues) rank from the third to the fifth place. The analytical framework also provides a ranking of the importance of timing over the 2010–2030 period in which investments are made. The results show that in general a fast trajectory (i.e. transformation early in the 20-year interval) is associated with relatively higher returns accruing to investments in selected feed types, compared to a “slow” trajectory. Fast action is therefore recommended.

‘The results of this study demonstrate that the assessment framework developed could be applied readily in other systems, and at the same time provides a basis that can be further built upon.

‘This peer-reviewed World Bank report was prepared under the guidance of Jimmy Smith, formerly of the World Bank and (since Nov 2011) now serving as director general of the International Livestock Research Institute (ILRI), in Nairobi, Kenya, and Francois le Gall of the World Bank by an ILRI team consisting of William Thorpe, Derek Baker and Shirley Tarawali with Rainer Asse, Augustine Ayantunde, Michael Blummel, Oumar Diall, Alan Duncan, Abdou Fall, Bruno Gerard, Elaine Grings, Mario Herrero, Chedly Kayouli, Ben Lukuyu, Siboniso Moyo, Ranjitha Puskur, An Notenbaert, Tom Randolph, Steve Staal, Nils Teufel, Francis Wanyoike and Iain Wright.

The road back to Rio: Turning straw into gold — Crop ‘wastes’ at the heart of greener livestock development

Posted on June 18, 2012 by Susan MacMillan

Key findings were presented today on ways to enhance the value of coarse crop ‘wastes’—better termed ‘residues’—as feed for cattle, water buffalo, sheep, goats and other ruminant farm animals. The talk was given at a ‘learning event’ that is part of Agriculture Day at the Rio-20 United Nations Conference on Sustainable Development.

Carlos Seré, former director general of the International Livestock Research Institute (ILRI) now serving as chief strategist for the International Fund for Agricultural Development (IFAD), delivered this presentation on behalf of Michael Blümmel, an animal nutritionist based in ILRI’s office in Hyderabad, India, who could not make the event as scheduled.

The gist of the presentation is that wheat and rice straw, maize stover, groundnut haulms and other residues of crops that remain after their grain or pods have been harvested for human consumption are major feed resources for livestock in developing countries. Widespread and increasing shortages of arable land and water in these countries are increasing the importance of these crop residues for livestock feed, and their importance will only increase over the coming decades as human population grows and as more and more people move out of poverty and begin adding more milk and meat to their diets.

In recent years, livestock and crop improvement researchers have worked together to improve the fodder value, in terms of both quantity and quality, of crop residues at their source. They’ve done this in crop improvement programs that incorporate fodder traits in crop selection, breeding and new cultivar release criteria. Key cereals and legumes are tackled and both conventional and molecular breeding techniques are employed. Fodder traders and feed processors have started employing additional interventions to further improve the superior crop straws and stover.

The following examples illustrate the many promising findings from this collaborative fodder research.

01 Nutritionally significant variations exist in crop residue fodder value among existing cultivars that can be exploited through simple phenotyping without detriment to primary crop traits such as grain and pod yields.
As a ballpark figure, 5 percentage units in digestibility can be exploited in crop residue fodder quality without detriment to gain or pod yield in all key cereal and leguminous crops. The advantage of daily milk yield accruing from 5% difference in digestibility of basal diet in well designed ration is about 5 kg per day due to a multiplicator effect from both higher energy concentration in the diet and higher intake.

02 Simple and network-sharable food/feed/fodder nutritional phenotyping techniques have been established, such as near-infrared spectroscopy (NIRS) platforms that support whole-plant crop improvement paradigms and programs.
ILRI NIRS platforms in India and Ethiopia are being used by other research programs (e.g., the new CGIAR Research Program on Livestock and Fish) and research organizations (e.g., the International Center from Tropical Agriculture and the International Centre for Agricultural Research in the Dry Areas). Staff of national agricultural research institutions from the Congo, Eritrea, Ethiopia, Rwanda, Tanzania and Uganda have been trained in the NIRS technology and have access to network-shared NIRS equations. NIRS is increasingly being used to test for more qualitative grain traits such as lysine, tryptophan, iron, zinc and polyunsaturated fatty acids, with the aim of optimizing whole plants. This collaborative research is facilitating the analysis of 50 to 100 cultivars every day and gaining information about all their pertinent grain and crop residue traits.

03 Fodder value can be further increased through conventional crop breeding (such as recurrent selection) and molecular crop breeding (such as quantitative trait loci [QTL] identification and backcrossing).
Identification of stay-green QTLs and their backcrossing into elite sorghum varieties could increase stover digestibility by 3 to 5 percentage units while also increasing the sorghum plant’s drought resistance and water-use efficiencies.

04 In mixed crop-and-livestock agricultural production systems, the rates of adoption of new crop cultivars improved for both food and feed/fodder traits appear to be better than that for adoption of new cultivars improved for food traits only.
In a recent maize project in East Africa, farmers ranked stover traits 2.4 and grain yield 2.9 on a scale of 3. Farmers were most likely to adopt new maize cultivars that had improved stover as well as grain traits. Anecdotal evidence from groundnut adoption studies in India suggests that farmers prefer relatively small additive advantages—say 10% more pod + 10% more haulm + 10% more haulm quality—over (often theoretical) drastic increases in pod yield.

05 Participants in fodder value chains for straw and stover profit from superior straw and stover.
Price premiums for 3 to 5 percentage units in digestibility are in the range of 10 to 30%. There is higher demand for higher quality crop residues and superior sorghum stover is now regularly transported more than 400 km in parts of India. There are significant employment opportunities in harvesting, chopping, transporting and selling these crop residues.

06 Further improvement of superior straw and stover, in the form of supplementation, fortification or densification, can be done in feed processing, with productivity levels achieved from such processed but largely by-product-based feeds being four or more times greater than current levels of production.
Complete rations based on more than on 80% by-products (50–60% straws and stovers) can support 15–16 kg of milk daily in dairy buffaloes, about 1 kg live-weight gain in cattle and 120–130 g in sheep. Complete rations are suitable for smallholder farmers because the rations need not entail complex feed processing options; simply chopping and supplementing residues can suffice.

07 Increasing current yields of animals in India, such as by doubling the average daily yield of 3.6 kg of milk (across buffalo, crossbred and local cattle herds), would reduce levels of greenhouse gases dramatically, decreasing methane emission from dairy production by more than 1 million tons per year.
This is straightforward; increasing average daily milk yields in India from 3.6 to 6 to 7 kg per animal per day would reduce methane production from dairy animals relative to the same amount of milk produced by about 1 million tons per year.

In addition, there are good prospects for mainstreaming such multi-dimensional crop improvement outputs. For example, new CGIAR Research Programs (such as those on maize, rice, dryland cereals, and grain legumes) have already adopted the approach and have incorporated fodder value as high-priority traits in these crops.

The road back to Rio: ‘LivestockPLUS Learning Event’ shows how better feed reduces poverty AND livestock ‘hoofprints’

Posted on June 18, 2012 by Susan MacMillan

Several hundred people in Rio de Janeiro today will be discussing and debating a topic not often included in high-profile meetings. The topic is how we can use improved livestock feed to reduce both poverty and climate change.

The discussions today will take place at one of 13 ‘learning events’ that are part of an Agriculture and Rural Development Day at the Rio+20 United Nations Conference on Sustainable Development. Staff from CGIAR Centres are helping to organize and are participating in events throughout this day.

Given that the key messages of this particular learning event run counter to much current thinking about livestock, the participants will share and discuss scientific evidence that demonstrates the benefits of improved feeding practices, particularly their potential for contributing significantly to climate change mitigation while improving livestock production.

Messages
On the table today are both fodders, coarse foods composed of entire plants or the leaves and stalks of cereal crops, and bulky grass or hay forages. The learning event, titled ‘LivestockPlus—How can sustainable intensification of livestock production through improved feeding practices help realize both livelihood as well as environmental benefits?’, will deliver the following three fundamental messages.

New feeding practices can increase livestock production while decreasing its ecological ‘hoofprint’

New livestock feeding practices, like the use of improved dual-purpose crops and high-quality forages, offer significant potential for sustainable intensification of agricultural production to enhance livelihoods while also reducing livestock’s ecological ‘hoofprint’.

Improved forages, like forests, will capture carbon

Improved tropical forages offer the further advantage of sequestering large amounts of carbon—on a scale similar to that of forests—with the possibility of reducing emissions of nitrous oxide and methane per unit of livestock product. There is evidence that the potential of sown forages to sequester carbon (assuming good pasture and livestock management) is second only to that of forests and that sown forages could realize 60–80% of agriculture’s total potential to mitigate climate change.

Better feeding practices will allow mixed crop-livestock farmers to produce more food more sustainably

If widely applied by the vast army of ‘mixed’ smallholder farmers, who raise livestock as well as grow crops, and who are the mainstay of global food security, improved livestock feeding practices could deliver huge increases in food production at reduced environmental cost against a background of rising livestock production and consumption in the developing world.

Evidence
The result of numerous global initiatives and extensive testing, this work offers practical examples of how improved feeds can raise the production and incomes of smallholder farmers. Superior forage grasses widely adopted in Latin America, for example, already generate up to USD4 billion in Brazil alone. And improved tropical forages have also been adopted widely in Southeast Asia since the start of their promotion in 1995. A recent review indicates that continued adoption of improved feeds, including sown forages, could significantly reduce greenhouse gases on a global scale, while enhancing the livelihoods of the one billion people dependent on livestock-cropping systems.

What remains to be done
To scale up these improved feed resources so that they contribute to a transformed food system, we need more precsie understanding of the impacts of livestock on climate change, with the impacts differentiated by specific livestock-cropping systems, as well as of the potential for improved feeding practices to mitigate climate change. To make livestock and crop production in the tropics more climate friendly through improved feeding practices, smallholders must be given stronger incentives to market their livestock products and to sequester carbon through improved land management. Smallholders might be encouraged to adopt sown (and carbon-storing) forages, for example, through schemes instituted to pay them for the environmental services they provide.

What could be achieved
With donor support for research to obtain conclusive data and to provide policymakers with support for their decision-making, a functional system for implementing the LivestockPlus concept and associated strategies could be available within the next 5–6 years.

The program for this learning event
The program for this learning event includes a keynote presentation on the role of forages and livestock production in mitigating greenhouse gas emissions by CIAT soil scientist and agroecologist Aracely Castro; this keynote will be followed by three short case-study introductions on the following topics.

Carbon sequestration in livestock production for climate change mitigation: Implications for policy development in Brazil, presented by Embrapa beef cattle researcher Davi José Bungenstab.

Livestock production and climate change in sub-Saharan Africa and Asia: Technical innovation for environmental and livelihood benefits, presented by Carlos Seré, former director general of ILRI and now chief strategist for IFAD (note: Seré is speaking on behalf of ILRI animal nutritionist Michael Blümmel).

Climate-smart silvopastoral systems for a green livestock economy, presented by CATIE director Muhammad Ibrahim.

These case study presentations will be followed by parallel group discussions on each of the three cases to answer such questions as:
What are the main research findings that support the technological or policy innovation, including evidence of livelihood and environmental benefits?
What were key lessons learned from the research leading to this innovation?
What are the requirements for scaling it up?

The session will close with a moderated panel discussion in plenary with the keynote speaker and case study presenters.

Institutions involved
CATIE is a regional centre of excellence based in Costa Rica that works on solutions for the environment and development in rural communities in Latin America and the Caribbean.

CIAT, the International Center for Tropical Agriculture, based in Colombia, works to increase the eco-efficiency of agriculture to reduce hunger and poverty and to improve human health in the tropics.

EMBRAPA is the Brazilian Agricultural Research Corporation, which works for the sustainable development of Brazilian agribusiness.

ILRI, the International Livestock Research Institute, based in Africa, works to reduce hunger, poverty, ill health and environmental degradation through enhanced livestock systems for poor people in the developing world.

Presenters at the event
This learning event will be chaired by Elcio Guimarães, who is director of research for Latin America and the Caribbean at the International Center for Tropical Agriculture (CIAT). Discussions at the session will be summarized by Nathan Russell, a key organizer of this session who leads corporate communications work at CIAT. One of the three scheduled case study speakers, Michael Blümmel of ILRI, is unable to attend; his presentation will be made by Carlos Seré, former director general of ILRI and now chief strategist for the International Fund for Agricultural Development (IFAD).

This very brief photofilm (1:23 minutes) shares the memorable and powerful story of Gebremichael Desta, an Ethiopian farmer whose life has changed by the use of improved livestock feed.

If you climb up the rickety ladder on to the roof of the stone dwelling where Gebremichael Desta lives with his family and livestock—he keeps his hay on the roof—you can gaze across a world which looks much as it must have done many centuries ago. Ploughmen shout encouragement to their oxen, women urge pack animals over the stony ground and buzzards wheel above the terraced fields. There is not a machine in sight; nothing to indicate that this is the 21st century.

But appearances can deceive. ‘The difference between the past and present?’ muses Desta. ‘It’s like the distance between the sky and the earth.’ Today, the families living in these remote highlands—much of Tigray, in northern Ethiopia, is over 2000 metres above sea level—learn about the importance of family planning and good nutrition. Older generations never did. ‘When I was young, we were entirely dependent on traditional medicines if we fell sick, but now we have access to modern health care,’ says Desta.

Recent years have also witnessed dramatic changes in the way he and his neighbours manage their land and livestock. A few years ago, at this time of day, his animals—two oxen, a dairy cow and calf, a donkey, 10 sheep—would have been grazing in the valley below, watched over by one of his five children. Now they remain at the homestead, and the fodder is brought to them, rather than the other way around.

These changes have been inspired by a five-year project, Improving Productivity and Market Success of Ethiopian Farmers or IPMS, in short, which is funded by the Canadian International Development Agency and managed by the International Livestock Research Institute (ILRI) on behalf of the Ministry of Agriculture and Rural Development. In 10 districts across Ethiopia, the project has helped to improve the value chains—the links between producers, the suppliers of farm inputs and markets—for a range of crops and livestock products.

The project began with a lengthy series of consultations with farmers and local government staff. Together, they identified which farm commodities had the potential to improve local incomes and livelihoods. ‘The main candidates were milk and butter, sheep for fattening and beekeeping,’ recalls Gebremedhin Woldewahid, the project’s research and development officer in Atsbi-Wenberta District. ‘But the more we talked, the more we realised there was a major limiting factor for all these commodities—a lack of nutritious fodder.’ Much of the district suffered from overgrazing and heavily degraded soils. Tackling this was to be a priority.

A fairer, greener world

‘In 2006, before the project really got under way, this valley would have been parched and dusty and full of livestock at this time of year,’ explains Kidan Kindeya, a young woman who works as a development agent for Habes Peasant Association, of which Desta is vice-chairman. Today, there is not a grazing animal in sight and the vegetation is green and lush. Here and there, the grass has been harvested with a scythe; elsewhere it is almost knee-high, despite the fact that there has been little rain recently.

It is now three years since the peasant association agreed to ban grazing in the valley bottom, an area of some 280 hectares, and allow the land to regenerate naturally. ‘Before we enclosed the area, the ground was very compacted, especially by horses, and the grass was sparse and unpalatable for our sheep and cows,’ recalls Desta. ‘Now we can harvest our plots three times a year, and the quality of the fodder is excellent.’

There are numerous benefits to the ‘cut and carry’ system now operating in many valleys in Atsbi-Wenberta District. ‘My milk yields have risen and my animals are much healthier,’ says Desta. He also believes that by keeping animals at the homesteads, there is less risk of infectious diseases passing from one to another. The restoration of grazing lands has also led to an increase in flowers, providing a rich supply of pollen for honey bees. As a result, farmers practicing apiculture have benefited greatly from the new methods of pasture management.

In the past, children used to watch over the grazing livestock, which meant they did not go to school. Now they are attending classes. Farmers also used to spend a lot of time travelling long distances to buy fresh grass and hay. Now many have a surplus. This has proved especially important for the poorer households without livestock, which are often headed by widows. ‘They received no benefit in the past from areas like this, before the enclosures,’ explains Kidan Kindeya. ‘They had no livestock to graze, and there was nothing for them to harvest.’ Now, every family is allocated the same amount of land in the valley and those without livestock can harvest their grass and sell it. Two harvests a year yield fodder worth around 10,000 Ethiopian birr (USD740) per hectare.

Besides helping farmers to improve the supply of natural fodder, the local offices of the Ministry of Agriculture and Rural Development and the peasant associations have encouraged farmers to grow their own supplies. Training centres, many with colourful murals depicting the new ways of farming, have provided the know-how and materials to establish Napier grass, tree lucerne and other fodder crops. Now you see them growing around almost every homestead, besides plots of fruit and vegetables.

Spreading the word

‘When I was young,’ says an old priest outside the Orthodox church in Cherkos Haremere, ‘there was thick forest all over this hillside.’ All that remains is a fine stand of African olive trees around the church, the site’s sanctity protecting them from axe and fire. Over the years, a rapidly rising population and the ever-increasing demand for fuelwood, cropland and pasture transformed the rest of the landscape, much of which suffers from erosion and overgrazing. It is a scene repeated across the district, but gradually, thanks to the efforts of the peasant associations and the introduction of new management techniques, degraded land is being brought back to life.

Four years ago, farmers in Baati-ero agreed to establish enclosures on the sloping land between the valley bottom and the village itself. They kept their animals out, planted fast-growing grasses and leguminous trees, and dug long ditches to harvest and retain rainwater. ‘We hardly used to get any fodder here at all,’ says a local farmer, Tadele Teklay, ‘but this year I’ve been able to get about five donkey loads.’

The farmers are so impressed by what they have achieved that they recently decided to establish enclosures in the valley bottom – something they originally resisted. Many, like Teklay, have also decided to reduce the number of livestock they keep. ‘Now, we don’t talk about how many animals we have, but how much money we can make from each of them,’ he says. ‘It’s the quality that matters, not the quantity, and the better the feed, as well as the breed, the more money we’ll make.’

Much of the technical advice that has enabled farmers to improve their productivity and gain access to better markets has been provided by Gebremedhin Woldewahid and the IPMS project, but most of the training has been carried out by the local offices of the Ministry of Agriculture Rural Development and by development agents like Kidan Kindeya. ‘That means that when the project comes to an end, hardly anybody will notice we’ve left,’ says Woldewahid with satisfaction.

One of the reasons why many of the activities encouraged by IPMS are spreading swiftly is because they make good financial, as well as environmental, sense. ‘You can see that with the fodder enclosures,’ says Berhe Fiseha, who chairs the project’s regional advisory and learning committee in Tigray. ‘They began establishing them in one peasant association, then they spread to four others, and now you’ll see enclosures being used to restore grassland all over the district.’

When asked what he has gained in recent years, Gebremichael Desta responds with one word: knowledge. He still regrets that he left school at the age of 17. He was a bright child, but his parents, traditional peasant farmers, had little appreciation of the value of education. Desta is justly proud that his eldest son has a diploma in agriculture and now works as a development agent, and his eldest daughter is studying at university.

‘If you want to survive, and you want to improve your life, then you must take advantage of the opportunities that come your way,’ he says. ‘There are many things which we now do differently, and we have many technologies that our parents never had or knew about. For me, knowledge is the key to everything.’

Straw matter(s) in Nepal

Posted on February 21, 2012 by Susan MacMillan

Dairy woman Nimala Bogati feeds her improved dairy cows green fodder. An ILRI-CSISA project on the Indo-Gangetic Plains of Chitwan District, in south-central Nepal, began in Sep 2010. Project staff are introducing residue-based feeding strategies supplemented with green fodder and concentrates to increase cattle and buffalo milk production (photo credit: ILRI/Susan MacMillan).

Starting in 2010, feed‐related aspects of dairying in two municipalities of Chitwan District in south-central Nepal have been investigated by staff members from the International Livestock Research Institute (ILRI) and a local Nepali non-governmental organization called Forum for Rural Welfare and Agricultural Reform for Development (FORWARD). This study set out to gain an understanding of the overall dairy production system in this district, with a particular focus on the livestock feeding strategies employed by farmers, and to identify key areas of the feeding strategy that could be altered to improve livestock productivity. A feed assessment tool called FEAST—a questionnaire that combines informal group discussions with structured interviews of key farmer informants—was used to rapidly assess on‐farm feed availability in a smallholder context.

Project staff from ILRI and FORWARD selected the municipalities of Gitanagar and Ratnanagar for this study because these sites were to become part of projects conducted by a multi-institutional Cereal Systems Initiative of South Asia (CSISA) in Nepal.

Farmers in this area generally have very small plots of land, averaging just 0.24 hectares, from which they produce a wide variety of crops. Rice, maize and wheat are the dominant cereal crops here. Goats and dairy cattle, predominately Holstein-Friesian and Jersey, are the main livestock kept. Some households also keep dairy buffaloes and poultry.

Dairying and other livestock activities contribute 63% of household income, cropping the remaining 37%.

Crop residues (most of which until recently were purchased) are the primary component of the feed for the farm animals and are relied on throughout the year.

Purchased concentrate feeds such as wheat bran and commercially mixed rations provide a significant portion of the dietary metabolizable energy and crude protein.

ILRI has been working with FORWARD for just over one year to improve understanding in these farming communities of key animal health, nutrition and reproduction concepts, so that the farmers can reduce the costs of their milk production, with purchased feed being the main cost.

Goats are the most popular livestock species kept within the area. Eighty percent of households keep 2–3 goats, which are used to fulfil household meat requirements and/or sold at irregular intervals for slaughter. Half the households here keep improved dairy cows, primarily Holstein-Freisian and Jersey, with each household keeping some 2–3 cows. About 10% of the households maintain local buffalo, and 5% improved buffalo such as Murrah, for milking, with each household keeping 1–2 animals. Local cows and buffalo are the cheapest dairy animals available, costing about 10,000Rs (USD$141) and 30,000Rs (USD$423) per head respectively. Improved cows and buffalo are available for 80000–90000Rs (USD$1128–USD$1269) per head. Dairy animals in this area produce approximately 3141 litres of milk per head per year, with sales of milk generating 249446Rs (USD$3519) per household annually.

The dairy animals are usually maintained in purpose built sheds in close proximity to the household and stall fed throughout the year. The shed will generally only have temporary walls that are erected during winter months to keep the animals warm. During summer months, the walls are removed to allow air to circulate around the animals to keep them cool.

Notes
About FEAST
Feed for livestock is often cited as the main constraint to improved productivity in smallholder systems. Overcoming this constraint often seems an elusive goal and technical feed interventions tend to adopt a scattergun or trial and error approach which often fails to adequately diagnose the nature of the feed problem and opportunities and therefore the means to deal with problems and harness opportunities. The purpose of the Feed Assessment Tool described here is to offer a systematic and rapid methodology for assessing feed resources at site level with a view to developing a site-specific strategy for improving feed supply and utilization through technical or organizational interventions. Output from FEAST consists of a short report in a defined format along with some quantitative information on overall feed availability, quality and seasonality which can be used to help inform intervention strategies. The tool is aimed at research and development practitioners who are working in the livestock sector and need a more systematic means of assessing current feed-related strategies and developing new ones.

About CSISA
The Cereal Systems Initiative for South Asia (CSISA) applies science and technologies to accelerate cereal production growth in South Asia’s most important grain baskets. CSISA works in partnerships in 9 intensive cereal-production ‘hubs’ in Bangladesh, India, Nepal and Pakistan to boost deployment of existing crop varieties, hybrids, management technologies and market information. CSISA is funded by the Bill and Melinda Gates Foundation and the United States Agency for International Development and conducted by the International Maize and Wheat Improvement Program (CIMMYT), the International Food Policy Research Institute (IFPRI), ILRI and the International Rice Research Institute (IRRI).

ILRI DAIRY FEED INTERVENTIONS IN SOUTH ASIA
Last September, ILRI held a workshop in Dehradun, northern India, to develop a tool for feed technology screening and prioritization. Last December, ILRI and national research institutions and NGOs from Bangladesh, India and Nepal conducted dairy feed experimental trials and demonstrated better use of crop residues for feeding to their dairy cows. Thirteen participants from four sites in Haryana, India (National Dairy Research Institute); Bihar, India (Bihar Veterinary College, Sarairanjan Primary Agricultural Cooperative Society); Chitwan, Nepal (Forum for Rural Welfare and Agricultural Reform for Development); and Dinajpur, Bangladesh (Bangladesh Livestock Research Institute, Cooperative for Assistance and Relief Everywhere) shared their results of the feed intervention trials and related training activities.

ETHIOPIAN LIVESTOCK FEEDS PROJECT (ELF)
This week (21–22 Feb 2012), an inception workshop for an Ethiopian Livestock Feeds Project (ELF) is taking place at ILRI’s campus in Addis Ababa, Ethiopia. The project involves a short scoping study that will be used to help further develop and test rapid livestock feed assessment methods such as FEAST and Techfit. This work is funded by the Australian Centre for International Agricultural Research.

Rural transformation: How a dairywoman and beekeeper in the Ethiopian highlands turned their farms into profitable businesses linked to markets

Posted on February 3, 2011 by Paul Karaimu

Participants in this week’s ‘Workshop on Gender and Market-oriented Agriculture’, organized by ILRI in Ethiopia, visited two women farmers in Debre Zeit (Picture credit: ILRI/Habtamu)

On the third and last day of the ‘Workshop on Gender and Market-oriented Agriculture: From Research to Practice’ (AgriGender2011), organized by the International Livestock Research Institute (ILRI) this week (31 January–2 February 2011) in Ethiopia, two women farmers shared how they transformed themselves from farm labourers to agricultural businesswomen as they increased both their food production and marketing.

In a field visit to Debre Zeit, a town 50 kilometres southeast of Addis Ababa, the workshop participants visited Tigist Weycha, a mother of three and dairy producer. Weycha is a member of the local Ada’a Dairy Cooperative that processes about 5,000 litres of milk a day obtained from farmers in the area. She owns 12 cattle, including 7 improved-breed dairy cows. She has been in the milk business for six years, though her livestock husbandry experience goes back 11 years.

‘Each day I deliver between 50 and 60 litres of milk to the cooperative and I make about 5,000 Ethiopian birr (US$294) a month in profits. Dairying is very profitable here and income from this work is maintaining my household and educating our children,’ says Weycha. Her husband, after losing his job when a project that employed him in the town closed down, joined her in the farm work and they are now together enjoying the benefits of keeping dairy cows.

Weycha is a beneficiary of the Improving Productivity and Market Success of Ethiopian Farmers (IPMS) project, which began in 2005 with funding from the Canadian International Development Agency. IPMS is implemented by ILRI and other partners on behalf of the Ethiopian Government.

A goal of the IPMS project was to help improve livelihoods of the poor in Ethiopia by linking rural smallholder producers to markets. The project connected Weycha with the Ada’a Cooperative, which became a reliable buyer of her milk. Project staff also gave her training in managing her dairy farm business and animals and the benefits she has accrued are clear to see six years on.

‘The cooperative pays us after every two weeks. And this money is deposited into a personal bank account which I manage for the benefit of my family,’ Weycha says.

Weycha is one of the successful dairy farmers in Debre Zeit. With support from her family and her husband—who is trained in animal health management and uses this expertise on the farm—she has excelled as a model dairy farmer. And this despite the fact that dairy farmers in this area have to pay dearly for veterinary services and drugs, when these are available, and for animal feeds, the price of which fluctuates. Weycha feeds her cows mostly on maize and teff residues and alfalfa. She supplements this with oil cake and molasses that she buys every two weeks from traders in Debre Zeit town.

Participants also visited another beneficiary of the IPMS project, Elfnesh Bermeji, a beekeeper who makes 50 birr for every kilogramme of honey she sells from her 20 modern and traditional hives. She harvests the honey two times in a year and the income she has earned from selling the honey has enabled Bermeji to build a home and to educate her children, who are now supporting themselves after graduating from university.

These two Ethiopian women are examples of the many benefits of targeting women for capacity building. Their successes are bettering not only their own lives, but also those of members of their families and communities. These two women have, with the help of their spouses and families, transformed themselves into entrepreneurs in an area where few other women have managed to break with rural traditions. The success stories of Weycha and Bermeji should now give other women, and men, confidence to do the same.

Food-feed crops research: A synthesis

Posted on January 17, 2011 by Peter Ballantyne

In December 2010, a special issue of Animal Nutrition and Feed Technology focuses on the fodder quality of crop residues and how this can be improved through the close collaboration of crop and livestock scientists in multi-dimensional crop improvement programmes.

Over the next two decades, rapid urbanization and rising incomes in the developing world will continue to feed an on-going livestock revolution. In India, this boom in the production of animal products will be driven by a demand for milk that is projected to increase by more than 80 million tons in 15 years.

Smallholder livestock producers will have new opportunities to raise their incomes on the back of this increasing demand, particularly the vulnerable communities occupying dry, marginal and remote lands that rely most heavily on their animals.

Feed scarcity and resulting high feed costs are one of the major constraints and threats to higher benefits from livestock otherwise offered by the rising demand for livestock products. New strategies for improving feed resources are urgently needed, but they need to take into account the increasing scarcity of the natural resource base, particularly of arable land and increasingly water.

Crop residues are the single most important feed resource in India, and the national feed resource scenarios predict that their importance for livestock feeding will further increase. In several parts of India, weight for weight, crop residue prices are now approaching, and sometimes even exceeding, half the prices of their grains.

Crop residues do not require specific land and water allocations, since these are required in any case for the production of grains. Unfortunately, the fodder quality of crop residues is often low, and in the past decades, efforts have been invested in upgrading the feeding value of crop residues (implicitly from cereals since leguminous residues can have excellent fodder quality) through chemical, physical and biological treatments.

However, these approaches have seen little adoption by farming communities. A different paradigm has been developed in this this special issue of Animal Nutrition and Feed Technology, namely, the improvement of crop residues at source through close collaboration of crop and livestock scientists in multidimensional crop improvement programs. Until recently, fodder traits of crop residues were largely ignored in crop improvement, although farmers were traditionally aware of differences in the fodder quality of crop residues even within the same species. Farmers’ perception of crop residue fodder traits could effect the adoption of new cultivars, resulting sometimes in the rejection of new cultivars that have been improved only for grain yields.

In response, the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) and the International Livestock Research Institute (ILRI) together with their partners from the Indian Council of Agricultural Research (ICAR) initiated several multidisciplinary research projects to create crop cultivars that better match the need of farmers, particularly in mixed crop-livestock systems which are dominant in many parts of the developing world.

The fundamental issues explored in these collaborative projects, and expounded in this special issue, are: (1) availability of livestock nutritionally-significant cultivar-dependent variation in crop residue fodder quantity and quality; (2) relationships between crop residue fodder traits and primary food traits and possible trade-offs between the traits; (3) technologies for quick and inexpensive phenotyping of large set of samples for simple fodder quality that are well correlated with actual livestock productivity; (4) breeding techniques for further genetic enhancement towards food-feed traits; and (5) upgrading crop residue fodder in value chains through densification and fortification.

These valuable contributions serve as eye-openers to researchers and present a strong case for further strengthening such collaborations between national and international crop and livestock institutions. More importantly, they pave the way for expanding work on the promising approach of producing dual-purpose varieties of key crops for mixed crop-livestock systems given that these systems will be crucial in feeding the next 3 billion people.

Feed-plus-food sorghum crop varieties are feeding India

Posted on November 2, 2010 by Susan MacMillan

Cover of the CGIAR Annual Report 2009 (photo credit: CGIAR/Palmer).

The annual report for 2009 for the Consultative Group on International Agricultural Research (CGIAR) is out.

The International Livestock Research Institute contributed the following article about development of crops that feed people and animals both.

'New varieties of sorghum are bred to better meet the needs of India’s 208 million livestock farmers for animal feed, as well as to feed its growing human population.

'Throughout the tropics, a lack of feed keeps farm animals underweight and underproductive, thereby preventing some 600 million poor farmers and herders from meeting fast-rising global demand for milk and meat. But thanks to a partnership between India ́s National Research Centre for Sorghum (NRCS), the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) and the International Livestock Research Institute (ILRI), new varieties of sorghum are being developed that can provide both nutritious food for humans and high-quality feed for livestock.

'The single most important source of animal feed on many small farms in Asia and Africa is not grass but rather the stalks, leaves and other residues of crop plants after harvesting. In India, for example, 44% of the feed that annually sustains all the country ́s cattle, buffalo, goats, sheep and camels is made up of such crop wastes. The rest comes from planted forages and a shrinking area of pastures and other common lands. Expensive feed concentrates—the mainstay of livestock production in rich countries—are used only occasionally.

'Although crop residues (also known as stover) have become the main source of feed for farm animals in developing countries, crop breeders have continued to focus their efforts solely on increasing grain yields and not on improving the yield and quality of stover. The NRCS-ICRISAT-ILRI partnership seeks to redress this oversight by focusing on sorghum, an important staple crop in India that is grown on nearly 10 million hectares throughout the country.

'Small-scale entrepreneurs in India are developing new livestock feeds using new dual-purpose, food-plus-feed sorghum varieties.

'The researchers incorporated fodder quality traits in India ́s sorghum crop breeding trials and, in so doing, led breeders to identify sorghum varieties that give high yields of both grain and stover, as well as improved stover quality. The result is dual-purpose, food-plus-feed sorghum varieties that are now helping India’s 208 million livestock farmers close the livestock feed gap and feed India’s growing human population.

'The initiative has proved groundbreaking in demonstrating that traits for stover fodder quality and quantity can be incorporated into existing breeding programs to improve grain yields and has led the way for similar work on other major crops such as millet, groundnut, rice, maize and cowpea. New initiatives are also beginning for wheat and various leguminous crops.'
