Urinary Purine Derivatives as Index for Estimation of Ruminal Microbial Nitrogen Production in Sheep and Goats
Microbial-N production in the rumen can be estimated by using urinary purine derivatives (PD) as an index. A series of experiments were conducted to establish the relationship between urinary PD (allantoin, uric acid, xanthine and hypoxanthine) and feed intake, endogenous PD excretion and recover...
