Ethanol byproducts replace up to 25% of soybean meal in India’s compound feed

The expansion of grain-based ethanol production in India is driving increased use of dried distillers grains with solubles (DDGS) as a cheaper alternative to soybean meal. According to industry experts, DDGS have already replaced an average of around 25% of conventional soybean meal at organized compound feed mills, although substitution rates vary significantly across animal feed segments. The growing supply of ethanol byproducts is helping feed manufacturers reduce raw material costs and gradually reshaping domestic demand for soybean meal.

The main advantage of DDGS is their significantly lower cost compared with soybean meal. In India, soybean meal containing 45–48% protein costs Rs 55–59/kg, while rice-based DDGS with a protein content of 45–50% are priced at Rs 25–29/kg. Corn-based DDGS are even cheaper, trading at Rs 12.5–15.5/kg with a protein content of 28–32%. This price difference encourages compound feed manufacturers to increase the use of alternative ingredients, although inclusion rates depend on nutritional characteristics and feed quality requirements.

DDGS are increasingly used in poultry farming, dairy production and aquaculture. In broiler and layer feed formulations, they can replace 10–20% of soybean meal, while in concentrated cattle feed, substitution rates for soybean meal or oilseed cake can reach 30–50%. In aquaculture, DDGS derived from rice or corn can replace 15–25% of soybean protein, potentially reducing feed costs by 8–12% per kilogram of weight gain in fish and shrimp production.

According to the Grain Ethanol Manufacturers Association (GEMA), India’s annual DDGS production is estimated at 3.5–4 mln tons, of which approximately 600–700 thsd tons are exported. Industry estimates suggest that DDGS are already replacing around 1.2–1.5 mln tons of soybean meal annually in the domestic feed market. Meanwhile, India’s compound feed industry requires approximately 6 mln tons of soybean meal. Further expansion of ethanol production could intensify competition between DDGS and traditional protein-rich feed ingredients.

However, feed industry representatives emphasize the importance of maintaining consistent DDGS quality, as the nutritional characteristics of the product may vary depending on the raw materials used and production technologies. Monitoring protein content and conducting regular laboratory testing of individual batches remain particularly important. The continued development of India’s ethanol industry is expected to increase DDGS availability for feed manufacturers, while also intensifying competition for corn between biofuel producers and the livestock sector.
