| 摘 要： | 在玉米秸为主的日粮中每头添加膨润土１６ｇ／ｄ和羟甲基尿素２０ｇ／ｄ进行羔羊快速育肥试验。结果表明，羔羊日增重由对照组的６５．００ｇ提高到试验组的１２０．６３ｇ，二者差异显著（Ｐ＜０．０５）。饲料转化效率提高４６．０１％。４０ｄ后羔羊瘤胃液ｐＨ值明显降低。膨润土能改善羔羊瘤胃消化代谢并促进羔羊生长。

| Abstract: | A lamb fast fatting traial with a diet dominated mainly by maize straw in which 16 g bentonite and 20 g hydroxymethylurea per day were supplied to each lamb has been conducted. The results showed that the 120.63 g live weight gains of lamb in experimental was much higher than that of 65.00 g in control (P<0.05),and the rate of feed conversion efficiency was increased 46.01% comparing with that of control. There was a obvious decreasing tendency in rumen pH after 40 days. This results showed that digestion and metabolism in rumen were significantly improved by supplementing the diets with bentonite, of which dominated mainly by maize straw. |
