Low Fat Dried Distillers Grains with Solubles (LFDDGS) in Feedlot Finishing Diets

Read the complete report: Low Fat Dried Distillers Grains with Solubles (LFDDGS) in Feedlot Finishing Diets

A new research report looks at whether the content of low-fat distillers grains could attenuate negative effects of high dietary fat on ruminal fermentation, support improved rumen function and subsequently enhance overall nutrient digestibility, feed intake and utilization and feedlot cattle performance.

About this report:

Excessive dietary fat can negatively affect growth of fiber-digesting ruminal microorganisms and consequently decrease organic matter total tract digestibility, feed intake and overall performance in feedlot cattle. These effects interact to increase ruminal solids retention time, which effects a reduction in intake and overall feedlot performance. Therefore, low fat content of low-fat distillers grains could attenuate negative effects of high dietary fat on ruminal fermentation, support improved rumen function and subsequently enhance overall nutrient digestibility, feed intake and utilization and feedlot cattle performance.

Conclusions:

LF‐DDGS at up to 35% of diet dry matter provided equivalent growth and feed efficiency to conventional DDGS and corn-based diets. The value of LF‐DDGS is equivalent to conventional DDGS in diets of feedlot cattle.

Project outcomes:

Ethanol production in Minnesota has provided feedlot operators an opportunity to utilize ethanol coproducts in feedlot rations. This report will help feedlot producers make informed decisions on the use of distillers grains in their cattle diets.
