IIMR Seeks Funding to Manage Aflatoxin in DDGS for Safer Animal Feed

The Indian Institute of Maize Research (IIMR) is seeking funding to explore methods for controlling aflatoxin levels in Dried Distillers Grains with Solubles (DDGS), a by-product of ethanol production that the animal feed industry increasingly demands. IIMR has outlined several technologies and practices that can reduce aflatoxin to permissible levels of 20 parts per million (PPM), ensuring DDGS remains safe for use in animal feed.

Based in Ludhiana, IIMR recommends managing aflatoxin at the source by improving host plant resistance and adopting better agronomic practices. Additionally, proper management during transportation and storage can further lower toxin levels. The institute also suggests using fractionation techniques to reduce aflatoxin content while boosting protein levels in DDGS.

In response to concerns raised by the Department of Animal Husbandry regarding aflatoxin in DDGS, IIMR emphasizes the need to educate stakeholders. The institute proposes implementing guidelines that limit the use of DDGS in cattle feed to a maximum of 10%. This will prevent harm, even if the DDGS contains more than 20 PPM of aflatoxin, and protect human health, especially regarding milk consumption from cattle fed with DDGS.

Aflatoxin Management and Industry Response

Aflatoxin contamination in DDGS often results from maize with high moisture content, which, if not dried properly, can develop aflatoxin. When such maize is used for ethanol production, the DDGS produced may also contain higher toxin levels. To address this, the distillery industry must implement better management practices to reduce aflatoxin contamination.

In May, Godrej Agrovet’s managing director, Balram S. Yadav, reassured that Indian producers now produce good-quality DDGS. However, IIMR advocates for a dedicated project that addresses both aflatoxin management and the nutritional enhancement of DDGS, easing concerns within the animal feed industry.

In 2019, the Genetic Engineering Appraisal Committee (GEAC) established a panel to create draft guidelines for importing animal feed, including DDGS. Later, the Department of Animal Husbandry published a consolidated list of approved animal feeds for import, which included DDGS. However, since genetically modified maize is widely used in producing DDGS in the US and Brazil, GEAC import permits are required.

Conclusion

IIMR’s request for funding to manage aflatoxin in DDGS highlights the pressing need for improved practices and technologies in the distillery and animal feed industries. While the demand for DDGS is growing in India, ensuring the product’s safety through proper management is critical for its continued success. Feed industry stakeholders must stay informed about potential regulations and consider implementing measures to reduce aflatoxin contamination to safeguard both livestock and consumers.
