The objective of this research was to estimate the intestinal digestibility of rumen-undegradable protein (RUDP) by a three-steps procedure. The evaluated feeds were the soybean meal, cottonseed meal, wheat middlings, corn meal, corn gluten meal, whole raw soybean, whole raw cottonseed, fishmeal, meat meal and blood meal. Firstly, the feeds were incubated in rumen during 16 hours to determine the rumen-undegradable protein, the residue was incubated with pepsin solution during 1 hour, and pancreatic solution during 24 hours at 380C, […]
