Manipulation of nitrogen digestion by sheep using defaunation and various nitrogen supplementation regimens.
Five ruminally, duodenally, and ileally cannulated sheep (average BW 62 kg) were fed 65% roughage: 35% concentrate diets (CP = 15%) in a 5 x 5 Latin square design to study the applicability of using a combination of defaunation with N supplements (soybean meal [SBM], corn gluten meal [CGM], blood meal [BM], urea, and casein) with different extents of ruminal degradation to manipulate microbial ...
متن کاملDigestion of concentrates in sheep
I. Four sheep were given four diets containing proportions of rolled barley and soya-bean meal varied to provide 10.3, 13'3, 16.1 and 19.9 % crude protein in the dietary dry matter; the treatments were given according to a 4 x 4 Latin square design. The mean daily intake was 989 g dry matter. The apparent disappearance of protein, ash, ether extractives and carbohydrate before the abomasum, bet...
متن کاملReponses of sheep to a vaccination of entodinial or mixed rumen protozoal antigens to reduce rumen protozoal numbers.
Two rumen protozoa vaccine formulations containing either whole fixed Entodinium or mixed rumen protozoa cells were tested on Merino sheep with the aim of decreasing the number and/or activity of protozoa in the rumen. Negative control (no antigen) and positive control (Tetrahymena corlissi antigens) treatments were also included in the experiment. Blood and saliva were sampled to measure the s...
متن کاملEffects of cold exposure on digestion, microbial synthesis and nitrogen transformations in sheep.
I. Six closely shorn sheep were given brome grass (Bromus inermis) pellets at the rate of 59 or 98 g dry matter (DM)/h and maintained at ambient temperatures of 2-5' and 22-25' for 35 d. Measurements of digestion, rate of passage of digesta, and nitrogen transformations were made during the last 13 d of temperature exposure. 2. Cold exposure at the lower level of intake reduced the apparent dig...
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...
