Nitrogen Metabolism in the Ruminant: a Review
Current systems for the evaluation of protein-feeds for ruminants take account of two principal nitrogen (N) requirements. One is to satisfy the needs of the rumen micro-organisms in order to maximize. microbial protein yield this N can largely be provided in any form that will give rise to enough ammonia in rumen fluid. The other N requirement is for a dietary source of true protein that wi,ll...
متن کاملGlucose metabolism in the ruminant.
265 with the consequent induction of enzymes involved in fatty acid synthesis, and that any difference between the metabolism of fructose and glucose is comparatively unimportant as a factor determining the hyperlipidaemic effect of sucrose. T o conclude, I will return to the species with which I began. The few sucrose or fructose tolerance tests that have been conducted on human volunteers (Bu...
متن کاملAcetate Metabolism in the Ruminant.
Biochemists have long recognized the central role of acetate in the energy metabolism of most forms of life. But whereas for most organisms the supply of acetate, or rather its active form, acetyl coenzyme A, is almost entirely endogenous, ruminant animals have a large exogenous supply of acetate, which is produced in the rumen by microbial fermentation of ingested foodstuffs. In the ruminant, ...
متن کاملInfluence of the novel urease inhibitor N-(n-butyl) thiophosphoric triamide on ruminant nitrogen metabolism: II. Ruminal nitrogen metabolism, diet digestibility, and nitrogen balance in lambs.
Three lamb metabolism experiments were conducted to investigate the effects of chronic administration of the novel urease inhibitor N (n-butyl) thiophosphoric triamide (NBPT) on ruminal N metabolism, fermentation, and N balance. In Exp. 1, ruminally cannulated wethers (n = 28; 45.0 +/- .9 kg) were administered one of seven doses of NBPT (0 [control], .125, .25, .5, 1, 2, or 4 g of NBPT daily) a...
متن کاملRuminant Nutrition: Ruminal Metabolism
Cultivation of algae for biofuel would result in the production of significant amounts of post-extraction algal residue (PEAR). The economic viability of algae as source of biofuel is dependent on deriving value from PEAR. Livestock feed is an attractive option for PEAR because of the successful utilization of other co-products by ruminants. While sufficient quantities of PEAR were not availabl...
