Role of rumen butyrate in regulation of nitrogen utilization and urea nitrogen kinetics in growing sheep.
Butyrate, a major rumen VFA, has been indirectly linked to enhancement of urea recycling on the basis of increased expression of urea transporter in the rumen epithelia of steers fed a rumen butyrate-enhancing diet. Two studies were conducted to quantify the effect of elevated rumen butyrate concentrations on N balance, urea kinetics and rumen epithelial proliferation. Wether sheep (n= 4), fitt...
متن کاملUtilization of Urea and Urease Treated Rice Straw by Indigenous Growing Cattle
The experiment was conducted to study the effect of treatment of rice straw with urea and a urease containing midden soil on the chemical composition of treated rice straw, feed intake of the animals, nutrients digestibility, body weight gain, feed conversion efficiency and overall economy of feeding for a period of 105 days. Twelve indigenous growing cattle (live weight 130.00±1.67 kg) were se...
متن کاملRelationship of whole body nitrogen utilization to urea kinetics in growing steers.
Urea kinetics were measured in 2 experiments, with treatments designed to change protein deposition by the animal. Our hypothesis was that increased protein deposition by cattle (Bos taurus) would reduce urea production and recycling to the gastrointestinal tract. Urea kinetics were measured by continuous intravenous infusion of (15)N(15)N-urea followed by measurement of enrichment in urinary u...
متن کاملThe net utilization of ammonium nitrogen by the growing rat.
While it is well known that ruminants (with the aid of rumen microorganisms) can utilize ammonium salts and urea in lieu of dietary protein,” 2 it has long been held that monogastric animals cannot.’ In view of the findings of Foster, Schoenheimer, and Rittenberg3 that dietary ammonium N15 is rapidly incorporated into rat tissue proteins, it seemed possible that the nitrogen of ammonium salts m...
متن کاملEnergy Utilization of Growing Chicks in Various Nutritional Conditions
For the last two decades, energy utilization of growing chicks has been studied more and more. This paper focuses on the energy utilization estimated by the metabolizable energy (ME) values and the efficiency at which ME is used for growth of chicks under various nutritional environment. Degree of saturation of dietary fats is responsible for nitrogen-corrected apparent metabolizable energy (AM...
