Extract

In situ dry matter and protein degradation of urea supplemented whole-crop barley in the rumen of Mehraban rams were studied. DM degradability estimated from disappearance of DM from dacron bags. The degradable fraction CP is converted to ammonia, fatty acids and CO2, with a portion of ammonia being used for microbial protein synthesis in the rumen. The undegradable fraction escapes digestion in the rumen and subsequently available for intestinal digestion and absorption.
