Wrinkle: Research Challenges the Perception of DDGS & Milk Fat Depression

Dairy

Research Summary

Feeding ingredients that contain greater amounts of unsaturated fat tend to increase the chance of milk-fat depression in lactating dairy cows. Unfortunately, many producers saw this effect when they first started feeding DDGS prior to the ethanol industry's movement towards oil extraction. As a result, many producers and nutritionists still perceive that DDGS causes cows to produce less milk fat. However, a summary of peer-reviewed data challenges this perception.

Wrinkle: Research Challenges the Perception of DDGS & Milk Fat Depression

As the ethanol industry continues to extract more oil from DDGS, we see greater nutritional value for lactating dairy cows. Previously, greater amounts of unsaturated fat in DDGS limited the amount of DDGS we could feed because of concerns with milk fat depression. As fat content of DDGS continues to decrease, we now have an opportunity to feed greater concentrations of DDGS and capture more feed cost savings.
