Extract

Modern protein evaluation systems for ruminants describe the supply and requirement of true protein that can be absorbed from the small intestine. Amino acids that are available for absorption from the small intestine is primarily the sum of those of microbial protein that is synthesized in the rumen by microorganism and dietary by-pass protein ( Harstad and prestlØkken, 2001). The objective of this experiment was to determine the DM, CP and AA disappearance from barley grain (BG) and corn grain (CG) in the rumen, small intestine and total tract of steer.
