Opening the door to commercial fodder production

Written by Sarah McLaughlin on November 17, 2022. Posted in Features.

The paired challenges of population growth and climate change have put smallholder farmers in Zambia in a squeeze. In the Southern Province, the center of agricultural production for the nation, smallholder dairy farmers struggle to increase their production of fodder to commercially viable levels in the face of a long dry season that climate change is intensifying.

Smallholder farmers looking to support their families, enhance the local food supply, and sustain economic growth in their areas are at a distinct disadvantage because agriculture in Zambia is dominated by massive commercial operations with plentiful capital, large tracts of land, and expensive machinery, with most of their output marked for export.

The International Maize and Wheat Improvement Center (CIMMYT) is partnering with the German development agency Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) and the University of Hohenheim to identify key barriers and sustainable pathways to smallholder farmer success through a mechanization working group. This work is being carried out through the global initiative One World No Hunger, which launched Green Innovation Centers for the Agriculture and Food Sector (GIC) in 15 member countries in 2014.

“Mechanization is a critical aspect of responding to these problems and the core business of the GIC is to develop knowledge,” said Chimuka Mulowa, a GIC cooperative development advisor based in Choma, Zambia. “Our efforts provide training to smallholder farmers with a focus on adaptive mechanization as a critical ingredient in a holistic approach. Projects in the past have purchased equipment, but we integrate knowledge with existing infrastructure.”

In Zambia, the GIC works with 22 cooperatives to reach 10,000 small-scale farmers with training sessions on fencing land to grow grass, climate smart breeding, irrigation, and more. The GIC has reached their training goal, but implementation of new practices has been more difficult, with only about half the farmers adopting what they have learned so far.

To better understand the challenges smallholder farmers face in Zambia, Mulowa and the GIC partnered with researcher Vuyo Maphango, who was completing his master’s degree in agricultural economics at the University of Hohenheim under the supervision of Lennart Woltering, a senior scientist at CIMMYT. Woltering developed a tool called Scaling Scan which analyzes barriers to growth for successful innovations in the pilot stage and brings focus to key ingredients for expansion.

Mulowa and Maphango used Scaling Scan to assess the progress of the GIC efforts in Zambia. As they expected, for smallholder farmers trying to get into commercial fodder production, financing was a challenge. At $35,000 USD for a machinery like hay balers used once per year, it can take a farmer up to a decade to recoup such an investment. But Scaling Scan also identified surprising challenges, such as a lack of collaboration and uneven dissemination of knowledge and skills.

“There was a lot of progress coming out of the Scaling Scan process,” Maphango said. “Growing the cooperatives of farmers is a critical GIC focus now, and this helps with the finance issues as well. Where farmers can’t afford to buy or develop high-quality seed, they can come together, share which seeds are working best for them, and help each other adopt best practices. Staying close as a cooperative also gives farmers stronger bargaining power with the ability to pool together finances.”

More affordable equipment will also help. Smaller, less expensive choppers and chuff cutters ($1500-2000 USD) are already available for silage production, but there is not a well-established tradition of employing silage production in Zambia, and farmers there have struggled to adopt it. Similar machines are making their way onto the market for fodder production and will require farmers to develop a new set of technical skills.

Mulowa and Maphango are also rethinking approaches to training. As an incentive, non-government organizations (NGOs) often pay participants for their time when they attend training sessions, but government ministries can’t sustain this practice beyond the end of a project due to lack of funding. For a deeper level of skill and knowledge development, GIC wants to help farmers see the benefit of training as providing its own incentive–continuing professional education will pay off, both in terms of better agricultural and business practices, and better financial outcomes. The key to this transition is results. When farmers see their yield improving because of skills and practices they developed in training, they will be hungry for more.

Success, for Zambian smallholders, is a door that is opening slowly but surely. “Early adopters are making progress,” Maphango said. “Some are growing their own grass, others are fencing their land and developing irrigation.” As these practices take root, and farmers share victories with cooperative members; the value of ongoing training becomes clear, and the door may open further for others to walk through.

New solutions for chopping fodder

Written by Emma Orchardson on August 3, 2021. Posted in Features.

It is a laborious and time-consuming process: chopping plant matter by hand to feed to livestock. In Cox’s Bazar district, in eastern Bangladesh, it is common practice. A mechanized fodder chopper can do the job more quickly and efficiently — yet this simple but effective machine has not seen much use in the region.

To address this, a collaboration between the International Maize and Wheat Improvement Center (CIMMYT) and aid organizations in the region is creating networks between farmers, agriculture service providers and the businesses that make and distribute the machines.

The Cox’s Bazar region is host to around 900,000 Rohingya refugees who were displaced from Myanmar. The influx of refugees has put a strain on resources in the region. This collaborative effort took place near the camps, in an effort to support capacity and economic development in the host communities nearby.

Though this collaboration has only been around for a few months, it has already seen early success, and received an award from the United States Agency for International Development (USAID). The award recognized the organizations’ “outstanding collaboration that contributed to increased and efficient livestock production through mechanization in the host communities impacted by the influx of Rohingya refugees.”

Mechanization and livestock collaboration

The project — funded by USAID — is a partnership between two existing efforts.

The first is Cereal Systems Initiative for South Asia – Mechanization Extension Activity (CSISA-MEA), which aims to boost the country’s private agricultural machinery industry while supporting local farmers. This initiative supports the mechanization of agriculture in Bangladesh, through increased capacity of the private sector to develop, manufacture and market innovative new technologies. CSISA-MEA is implemented by the International Maize and Wheat Improvement center (CIMMYT) in partnership with iDE and Georgia Institute of Technology.

The second is the Livestock Production for Improved Nutrition (LPIN) Activity, which works to improve nutrition and income generation among rural households in the region.

“We made a great collaboration with LPIN,” said Jotirmoy Mazumdar, an agriculturalist working with CSISA-MEA. “We’re very happy that our initiative helped us achieve this award. In this short time period, a new market opportunity was created.”

Nonstop chop

There are numerous benefits to using fodder choppers, according to Muhammad Nurul Amin Siddiquee, chief of party of LPIN. For one, having access to the choppers can save farmers around $7 (600 Bangladeshi taka) in labor costs per day, and reduce the amount of feed wasted by 10–15%. On average, a farmer can hand-chop 500 kg of forage or fodder each day, while the machines can process around 1,000 kg of the material per hour.

According to Siddiquee, giving chopped feed to livestock improves their productivity. One farmer’s herd of 17 crossbreed cows produced 115 liters of milk per day — he expects this to increase to 130 liters per day after feeding them fodder produced with a mechanized chopper.

“He can now save labor costs and four hours of his time per day by using the fodder chopping solutions,” he said, adding that the collaborative effort is “fostering increased livestock productivity and [farmer] incomes.”

However, Cox’s Bazar is far away from the center of Bangladesh, where most of these machines are produced. For example, there are more than 30 small engineering workshops in the more centrally located Khulna Division and they have cumulatively made 7,470 choppers.

“In Cox’s Bazar, it was almost impossible for those livestock farmers to get to know the chopper machines, and actually get access to them,” said Khaled Khan, team lead with iDE, who also aided in private-sector engagement.

So, the collaboration between CSISA-MEA and LPIN began connecting farmers and agriculture service providers with these fodder chopper producers and distributors. Moreover, it worked to increase knowledge of how to operate the machines among the farmers.

“Fodder choppers are an entirely new technology in Cox’s Bazar,” said Zakaria Hasan, CSISA team lead in the district.

Though it is still early days, the partnership has been met with a warm reception. Farmers and agriculture service providers cumulatively purchased 12 of the choppers within two weeks — each machine can support its owner and five other farmers — and three dealers are now selling the machines to meet farmer demand. In the region, 60 dairy farms are now purchasing chopped fodder for their livestock.

According to Khan, engaging the private sector in this project was essential. He explained that increasing the connectivity between the buyers and the sellers will help make the market larger and more stable.

“We found the perfect opportunity of supply and demand because their partners are demanding our partners’ service. The role of the private sector was the most important for the sustainability of this marriage of demand and supply,” Khan said.

“We want to establish a linkage between these two private entities. Our project’s job is to facilitate that, so that even after the project is over this networking continues in the future.”

New publications: Scientists find genomic regions associated with better quality stover traits in maize for animal feed

Written by Alison Doody on January 28, 2021. Posted in Publications.

Researchers from the International Maize and Wheat Improvement Center (CIMMYT) and the International Livestock Research Institute (ILRI) have identified new genomic regions associated with maize stover quality, an important by-product of maize which can be used in animal feed.

The results of the study, published this month in Nature Scientific Reports, will allow maize breeders to select for stover quality traits more quickly and cost-effectively, and to develop new dual purpose maize varieties without sacrificing grain yield.

The researchers screened diverse Asia-adapted CIMMYT maize lines from breeders’ working germplasm for animal feed quality traits. They then used these as a reference set to predict the breeding values of over a thousand doubled haploid lines derived from abiotic stress breeding programs based on genetic information. Based on these breeding values, the scientists further selected 100 of these double haploid lines and validated the performance of stover quality traits through field-based phenotyping.

The results demonstrate the feasibility of incorporating genomic prediction as a tool to improve stover traits, circumventing the need for field or lab-based phenotyping. The findings significantly reduce the need for additional testing resources — a major hindrance in breeding dual-purpose maize varieties.

Interestingly, the researchers found that increased animal feed quality in maize stover had no impact on grain yield, a concern raised by scientists in the past.

“The main purpose of this study and overall purpose of this CIMMYT and ILRI collaboration was to optimize the potential of maize crops for farm families, increase income, improve livelihoods and sustainably manage the crop livestock system, within limited resources,” said P.H. Zaidi, a maize physiologist at CIMMYT and co-author of the study.

“More than 70% of the farmers in the tropics are smallholders so they don’t have a lot of land to grow crops for grain purposes and separate stover for animal feed, so this is a very sustainable model if they grow dual purpose maize.”

By growing maize simultaneously for both human consumption and animal feed, farmers can get the most out of their crops and conserve natural resources like land and water.

Fodder for thought

The findings from this study also validate the use of genomic prediction as an important breeding tool to accelerate the development and improvement of dual-purpose maize varieties, according to CIMMYT Maize Breeder and first author of the study, M.T. Vinayan.

With the demand for animal feed increasing around the world, crop scientists and breeders have been exploring more efficient ways to improve animal feed quality in cereals without compromising grain yields for human consumption.

“Not all maize varieties have good stover quality, which is what we realized when we started working on this project. However, we discovered that there are a few which offer just as good quality as sorghum stover — a major source of livestock fodder particularly in countries such as India,” said Zaidi.

The publication of the study is a fitting tribute to the late Michael Blummel, who was a principal scientist and deputy program leader in the feed and forage development program at ILRI and co-author of this study.

“A couple of years back Dr Blummel relocated from the Hyderabad office at ILRI to its headquarters at Addis Ababa, but he used to frequently visit Hyderabad, and without fail met with us on each visit to discuss updates, especially about dual-purpose maize work. He was very passionate about dual-purpose maize research with a strong belief that the additional income from maize stover at no additional cost will significantly improve the income of maize farmers,” Zaidi said. “Michael was following this publication very closely because it was the first of its kind in terms of molecular breeding for dual purpose maize. He would have been very excited to see this published.”
