Effect of dietary nitrogen source on carbohydrate metabolism in the rumen of the young steer.
1. Steers, fitted with simple rumen and duodenal cannulas, were given diets of approximately equal parts of flaked maize and hay (A) (containing 16 g nitrogen/kg dry matter (DM) or diets of flaked maize and straw supplemented with decorticated groundnut meal (B), fish meal (C), or heated (D) or unheated (E) soya-bean meal (containing 24 g N/kg DM). Chromic oxide was given as a marker with the f...
متن کاملRumen Ammonia in Relation to Characteristics of the Diet and Parameters of Nitrogen Metabolism
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...
متن کاملUrease (EC 3.5.1.5) inhibition in the sheep rumen and its effect on urea and nitrogen metabolism.
The urease (EC 3.5.1.5) inhibitor, phenylphosphoryldiamidate (PPDA), was given by continuous infusion into the rumen of two sheep nourished by intragastric infusion and into either the rumen or abomasum of four sheep given a pelleted diet containing 119 g crude protein (nitrogen x 6.25)/kg dry matter. PPDA was given at 1 g/d in infusion sheep and 1.5 g/d in the normally-fed sheep. Measurements ...

متن کاملCitric acid metabolism in the bovine rumen.
Rumen microorganisms rapidly metabolize citric acid to carbon dioxide and acetic acid. The rate of metabolism varied between 0.00008 and 0.76 mumoles per g per min, the rate becoming higher as the citric acid concentration increased. The addition of potassium chloride to rumen contents decreased the rate of utilization. The results indicate that dietary citric acid is unlikely to accumulate in ...
