Quantitative 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 کاملLiquefied Wood as a Partial Substitute of Melamine-urea- Formaldehyde and Urea-formaldehyde Resins
Maritime pine (Pinus pinaster) sawdust was used to produce liquefied wood by the polyhydric method with acid catalysis. The process was optimized to produce the highest amount of liquefied wood. Wood liquefied at 160oC for 90 min was used in the adhesion tests. The bond strength of veneer glued with ureaformaldehyde and melamine-urea-formaldehyde resins and several mixtures of liquefied wood wi...
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 کاملNitrogen metabolism of growing lambs fed coastal bermudagrass as influenced by formaldehyde treatment and glucose.
Six abomasally-cannulated wethers (average initial weight 18 kg) were used in a split 3 X 3 Latin square design experiment with a crossover to determine effects of glucose (G) administered orally (O) or infused (I) into the abomasum on nitrogen metabolism and forage fiber digestion. Basal diets were Coastal bermudagrass (CBG) or CBG treated with 1% formaldehyde (F-CBG). Individual treatments we...
