摘 要:设计三种能量与蛋白质水平不同的配方日粮饲喂4月龄湖羊羔羊,为期60d。结果发现,三种配方日粮对公羔的日增重有显著影响,但对母羊的日增重无显著影响(P>0.05)。用配方Ⅱ和Ⅲ日粮饲喂的湖羊公羔,日增重极显著高于配方Ⅰ(P<0.01)。三种配方日粮饲喂羔羊,料肉比分别为2.15∶1、1.99∶1和2.09∶1;投入产出比分别为1∶1.54、1∶1.62、1∶1.55。这些结果表明,配方Ⅱ日粮(能量14.18MJ/Kg,粗蛋白16.53%)饲喂育肥湖羊的效果最佳;而配方Ⅰ日粮(能量13.41MJ/Kg,粗蛋白17.89%)和配方Ⅲ日粮(能量14.13MJ/Kg,粗蛋白17.87%)的效果次之。A feeding experiment was carried out for 60 days to investigate the effect of three different diets on fattening results for lambs of the Hu sheep aged 4 months The results showed that three diets have different effects on male lambs, but none on the females. The daily gain of the male lambs fed with diet Ⅱ and Ⅲ were remarkably higher than that of diet Ⅰ. The ratio of feed to body weight of both male and female lambs fed with three ingredients of diets were 2.15 : 1, 1.99 : 1, 2.09 : 1 ; and the ratio of input to output of three ingredients were 1 : 1.54,1 : 1.62,1 : 1.55. In conclusions, diet Ⅱ containing 14.18 MJ/kg of energy and 16.53% of crude protein was the best for fattening of Hu sheep , in comparison to di% et Ⅰ containing 13.41 MJ/kg of energy and 17. 89% crude protein and diet Ⅱ containing 14.13 MJ/kg of energy and 17.87% crude protein.
