摘要
本试验的目的是以肉脂兼用乌珠穆沁羯羊为试验动物,研究补饲不同剂量的稀土元素对肉羊增重的影晌,同时探讨其瘤胃内环境指标的作用效果。本次试验结果:补饲12mg/kg·d·w(试验Ⅱ组)为最佳投喂剂量。瘤胃内环境pH值各组无显著差异(P>0.05),试验Ⅱ组比对照组TVFA增高,但差异不显著(P>0.05)。可是,纤毛虫数量、C_2/C_3差异显著(P<0.05)。
The objective of this study is to investigate the effects of RE (Rare Elements) supplement on weight gain and rumen environmental index of meat-type sheep. The study showed: 12mg RE/kg.b.w/d)Group Ⅱ)is the best RE supplement dose There was no significant differencees in rumen) pH value between groups (P>0.05). Group Ⅱ is higher than control group in tVFA but the difference is not significant, the differences of protozoa number and C_2/C_3 ratio between those two groups were significant(P<0.05)
