The total and free amino acids content in the rumen of cows fed extruded rareseed meal

I. V. Nevostrueva, I. V. Vudmaska

Data about influence of extrusion used in cows diet rapeseed meal on ruminal protein and free amino acids contents are presented. Increasing of protein amino acids and decreasing of free amino acids quantity in the rumen of cows fed diet with extruded rapeseed meal has been pointed. Such effect may be cause by diminished proteolysis of extruded protein.

In the rumen protein fraction of cows fed diet with extruded rapeseed meal the higher contents of lysine, arginine, threonine, valine, methionine, isoleucine, phenylalanine, aspartate, proline and cystine have been found. Among free amino acids the concentrations of hystidine, arginine, methionine, leucine, glutamate and proline have been decreased.
