DDGS Inclusion Rates for Dairy Cattle: Best Practices
February 7, 2025
DDGS is a valuable ingredient in dairy cattle rations, providing protein, energy, and digestible fiber. Inclusion rates depend on overall diet structure, local raw material availability, and performance targets. This article covers best practices for formulating dairy rations with DDGS in Indian conditions.
Recommended Inclusion Levels
Dairy rations commonly use DDGS at 10–20% of total diet dry matter. Higher levels (up to 25–30%) can be considered with professional nutrition support, but must be balanced for amino acids, fiber, and minerals. The exact level depends on the base diet: if corn and soybean meal are expensive, DDGS can replace a portion of both.
Formulation Considerations
DDGS contributes bypass protein (undegraded in the rumen), which supports milk yield. Its fat content (8–10%) adds energy density. However, excess fat can depress fiber digestibility, so total dietary fat should be monitored. In India, where rice bran, DORB, and mustard cake are common, DDGS adds diversity and can improve palatability when combined with local ingredients.
Storage and Quality
During monsoon and high humidity, improper storage can lead to caking, mold, and nutrient loss. Stack bags 15–20 high max, ensure cross-ventilation, and keep bags off the ground. Use first-in-first-out (FIFO) and run mycotoxin checks on incoming shipments. Golden color indicates good quality; dark or burnt DDGS may have reduced digestibility.
