Can We Feed More Distillers Grains?

Distillers grains is a very good protein source (>30% crude protein) which is high in ruminally undegradable protein and is very good energy source (NEL ~1.02 Mcal/lb of dry matter; [DM]) for lactating cows and growing cattle. The modest fat concentration (10 to 12% of DM) and the readily digestible fiber (39% neutral detergent fiber; NDF) contribute to the high energy in distillers grains. The...
