A library of information on local bovine feed-ingredients can help Indian farmers formulate diets for their animals that lower enteric methane production.

India produces a whopping 25% of all global milk production. The country also has the largest population of bovines in the world— 303.76 million, including cattle, buffalo, mithun and yaks. That is especially significant when global warming is taken into account, since bovines produce enteric methane, a greenhouse gas, as a byproduct of their digestion process. 

One way to address production of enteric methane is to look for new ways to formulate bovine diets to reduce it. In the United States and other western countries, research into cattle diet formulations is ongoing. But as the statistics for India show, tackling dairy methane emissions must have a global focus.

“India is one of the most important stakeholders if we want to address the issues of the dairy industry globally,” said Dr. Ashish Kumar, Cornell Atkinson postdoctoral associate. “If production efficiency of animals is low, more methane emissions are produced. This seems to be the case in India.”

“India is one of the most important stakeholders if we want to address the issues of the dairy industry globally.”

Kumar and Dr. Shambhvi, Cornell Environmental Defense Fund postdoctoral fellow, are helping India deal with its enteric methane problem. The two researchers are part of Cornell’s Accelerating Livestock Innovations for Sustainability (ALIS) project. Working with BAIF Development Research Foundation, a nongovernmental agricultural development agency based in the Indian state of Maharashtra, Kumar and Shambhvi are collecting local feed ingredients for analysis. Private industry, such as Hindustan Feeds, and government agencies, such as Maharashtra Livestock Development Board, are also potential partners in the project.

“The differences in formulation of diets directly affects rumen methane emissions, host energy utilization and the productivity of animals,” Shambhvi explained. “So understanding the diet formulation and chemistry of individual feed ingredients is the starting point for establishing the relationship between diet, performance and emissions.”

Kumar and Shambhvi have identified 350 different feed ingredients used across India. “We are aiming to collect 15 to 20 replicates of each ingredient,” Shambhvi said. “The total samples collected should range from 5000 to 7000.”

The samples will include all types of ingredients available in different regions of India. However, the focus will be on those commonly fed by small-holder farmers. These include feed ingredients such as oat grain, cotton seed cake and rice bran, and fodder ingredients such as maize, sorghum and barley, Shambhvi said.

The researchers will collect samples from farmers’ fields and from farms under the jurisdiction of local partners. “After they are collected, they’ll be dried and ground in local laboratories before they are shipped to the US for analysis,” Kumar said.

The goal is to set up a feed library specific to India. It will then be available for integration into different ration-balancing software capable of recommending balanced feeds to improve the efficiency of dairy animals.

“We plan to also develop a user-friendly mobile-based application,” Shambhvi said. “We want small-holder farmers to be able to easily access the ration-balancing software, so they can learn about formulated diets based on feed ingredients available in their regions. 

"The more farmers who feed these diets, the better will be the productivity of the animals, which eventually will lead to better and sustainable dairy farming practices,” she added.
