Evaluation of nitrogen metabolites as indices of nitrogen utilization in sheep given frozen and dry mature herbages.
I . Twenty herbages at different stages of maturity containing from 0.77 to 5.23 g nitrogen/ 100 g organic matter were harvested, and green herbages were rapidly frozen and stored at 1.5’. Each herbage was offered at levels approximating to ad lib. to a group of three sheep, individually penned. Intake, digestion and retention of N were studied during a 10 d collection period after a 9 d prelim...
متن کاملQuantitative intestinal digestion of nitrogen in sheep given formaldehyde-treated and untreated casein supplements.
I. In two experiments, sheep prepared with a rumen cannula and with re-entrant cannulas in the duodenum and ileum were continuously fed on diets of dried grass, dried grass plus formalin-treated casein, or dried grass plus untreated casein. Paper impregnated with chromic oxide was given once daily via the rumen fistula. 2. In ten 24 h collections of digesta entering the duodenum and eleven 24 h...
متن کاملDigestion and nitrogen metabolism in sheep and red deer given large or small amounts of water and protein.
I. The interaction between nitrogen and water intake was studied in two ewes and two red deer hinds. They were given pelleted diets, at maintenance level, containing equal amounts of roughage but either rich or poor in nitrogen. The deer received 5 0 yo more food than the sheep. Water was given either in large amounts (sheep 5.0 1, deer 7.0 1 daily) or in small amounts (sheep 1.1 1, deer 2.4 1 ...
