Validation of the 3-steps Complete in vitro Method for Ruminant Feedstuffs Intestinal Digestibility

Abstract

The ruminants partially use the dietary protein in the rumen step of digestion. The undegraded part of this protein and also, its digestion in the stomach and small intestine vary depending on the type of feedstuff. The intestinal digestibility of the rumen undegraded protein RUP can be evaluated by the 3-steps in vitro method. In this study it was validated this method using the Ankom technology for two feeds: soybean meal and alfalfa hay.
