Ruminants microbial protein yield

A system for the quantitative nutrition of ruminant animals should embody the processes described, which requires that factors such as degradabUity, efficiency of nitrogen captme, microbial protein yield, digestibihty of microbial protein, digestibihty of dietary imdegraded protein and the trae biological value of the absorbed nitrogen or its essential amino acid content be quantified. 

Dietary protein escaping ruminal degradation and microbial protein synthesised in the rumen are the main sources that provide the ruminant with absorbed and metabohsable protein to support maintenance and production requirements. Two experiments were conducted to study microbial protein yield in dairy cows fed grass silage of different maturities at high and low level of feed intake.
