Urinary Nitrogen Excretion of Sheep Fed Nitrogen-free Diets
نویسندگان
چکیده
The urinary nitrogen excretion of sheep offered a low nitrogen diet was lower than when the sheep were fed a nitrogen-free mixture post-ruminally. This result is discussed in terms of Folin’s (1905) definition of endogenous nitrogen, and the nitrogen recycling and utilization which can occur in the rumen/reticulum of sheep. Reasons are given why post-ruminal feeding should give an endogenous nitrogen value near to the generally accepted inter-species mean.

Aspects of nitrogen metabolism in sheep-fed mixed diets containing tree and shrub foliages.
Data on N utilisation by sheep-fed diets containing foliages were analysed to develop prediction equations for N excretion in faeces (FN) and urine (UN), and to determine endogenous N excretion. Overall, 218 dietary treatments from forty-four publications were compiled in the database. This database was split into three subsets: without foliage in the diets (FL-0); foliage levels (FL) in betwee...
متن کاملEffect of Dietary Crude Protein Level on UT-B Expression and Nitrogen Efficiency in Growing Baluchi Male Lambs Fed Low or High Concentrate Diets
An experiment was carried out to evaluate how interactions between forage to concentrate ratio and dietary crude protein level may alter nitrogen efficiency and UT-B expression in growing Baluchi male lambs. Four Baluchi male lambs [30 ± 2 kg BW] were used in a 4 × 4 latin square design with 28-d periods and a 2 × 2 factorial arrangement of dietary treatments. The treatments fed forage: concent...

A study was carried out to investigate nitrogen metabolism in response to cecal ligation and colostomy in chickens. We used colostomized plus ceca-ligated chickens fed a low protein diet or a low protein diet supplemented with urea. When both types of diets were fed, nitrogen balance and utilization tended to increase by cecal ligation while total nitrogen excretion tended to decrease. Colostom...

Relationships between ammonia levels in rumen liquor and dietary nitrogen (N) intake, the N concentration in the diet, blood urea concentration and urinary N excretion were examined in sheep fed near ad libitum on diets varying widely in chemical composition and digestibility. Rumen ammonia was positively correlated with all measures but the best relationship was with the ratio of N to digestib...
