Abstract

The control of rate and extent to which dietary protein and amino acids are degraded in the rumen fermentation is a major determinant of the supply side of the equation. The possible ways of increasing the efficiency of the supply process are examined as well as strategies for correcting amino acid shortfalls. The control of rumen protein and amino acid degradation requires a thorough understanding of the degradative process, particularly peptide and amino acid metabolism. It helps in identifying ways to alter rumen microbial metabolism. Genetic selection or engineering has a bright future in the control of forage-protein degradation. Control of protein loss in the silo demands the attention of scientists where silages are extensively utilized. The current quantitative knowledge of the protein and amino acid needs of the host ruminants is inadequate. The impact of rumen-protected protein and amino acids and other manipulative strategies will be largely unpredictable until this deficiency is corrected.
