Nutrition labels tell you how much crude protein is in food. Protein is key to good health -- it's involved in immune function, oxygen transport and maintaining strong muscle tissue. Crude protein is a measure of how much protein is in food, based on laboratory tests studying the food's chemical composition. When you look for protein content on a food's nutrition label, the number you see refers to crude protein.
Additional protein beyond that supplied by the rumen microbes is provided in the form of undegradable protein (UIP). Non-protein nitrogen (NPN) can be used to meet some of the crude protein needs. NPN is first converted to ammonia in the rumen and then used by the rumen microbes to make microbial protein.hree protein sources contribute to the amino acid pool available for absorption at the small intestine. First of all, rumen microbes pass down to the intestine. In one study where researchers isolated rumen bacteria, crude protein as a percentage of bacterial dry matter ranged from 39 to 56%.
