Distillers grains (DG) are now common in many places feedstuff eating diet, generally ranges from 10-40 percent inclusion. Protein content ranged from DG high, ranging from 24 to 32 percent. However, a high proportion of protein in the rumen undegradable, it means that approximately 60 percent of the protein in ruminal degradation of DG escapes.
Undegradable protein not used by ruminal microorganisms to synthesize proteins, which may represent 50 percent of all the proteins that basically require cattle to productive processes such as milk production, weight and pregnancy.
Therefore, DG can potentially cause a deficit in protein degradable protein, a protein deficit can represent for the army, thus leading to a reduction in animal performance.
Therefore, one of the first questions beef operators may want to address is this: we should always expect degradable protein deficit when including the DG in the feedlot diet? The answer to that question is no.
-Inclusion of DG level, levels of dietary inclusion and types of wheat, and the type of processing the grain that is used;
