Extract

The contribution of rumen microorganisms to the protein absorbed in the intestine is a key factor to evaluate diets for ruminants, and the urinary excretion of purine derivatives (PD) has recently been proposed to estimate rumen microbial protein synthesis in cows (Verbic et al., 1990). This study refers to the relationship between PD excretion and the microbial nitrogen estimated according to recent protein systems for ruminants.
