摘要
采用全收粪(尿)法,进行消化代谢试验,研究生长猪饲粮中分别或同时添加半胱胺和酵母铬对饲粮养分的消化利用率影响。结果表明:生长猪饲粮中分别或同时添加半胱胺和酵母铬在一定程度上改善了饲粮干物质、无氮浸出物、粗蛋白质、总能、粗脂肪、粗纤维、钙和总磷等养分的表观消化吸收率,提高了氮的沉积率和表观生物学价值(P>0.05);酵母铬和半胱胺二者具有一定的协同作用。
Total collections of feces and urine were made to investigate the effect of varying quantity of cysteamine and chromium with separate or simultaneous addition in the diets of growing pigs. The results showed that cysteamine and chromium with separate or simultaneous addition in the diets for growing pigs, to some extent,improved the apparent absorption of dry matter, nitrogen-flee extract, crude protein, total energy, crude fat, crude fiber, calcium and total phosphorous. It also increased the retention of nitrogen and apparent biological value （P〉0. 05）. Yeast chromium and cysteamine had some synergistic effects.
