Abstract

Crude protein degradability and intestinal digestibility of the rumen undegraded protein were predicted in protein supplements for cattle (Vitex fodder yeast, soybean meal, rapeseed meal, sunflower meal, linseed meal, sesame meal, groundnut meal and cottonseed meal). The evaluation were performed by in vitro using enzymatic method. In order to determine the crude protein degradability the enzymatic method with bromelain was used. To determine the intestinal digestibility of the rumen undegraded protein the enzymatic method with pancreatin was applied. The results were adjusted using regression equations for protein concentrates and extracted meals.
