Excretion of purines in the urine of sheep in relation to duodenal flow of microbial protein



Excretion of purines in the urine of sheep in relation to duodenal flow of microbial protein



Swedish Journal of Agricultural Research 19(1): 45-52



Duodenal flow of microbial nitrogen (N) was estimated in cannulated sheep of the Swedish landrace breed. Collections of urine were made to compare estimated duodenal flow of microbial N and excretion of purine metabolites. Diets were fed at three levels of intake in Experiment 1 and a two levels of intake in Experiment 2. Duodenal flow of organic matter, N and microbial N increased significantly (p < 0.05) with increasing feed intake. The urinary excretion of purines, allantoin and total purines, was significantly (p < 0.01) related to the duodenal microbial N flow in the two experiments.
