摘　　要：文章旨在研究不同种类青干草对湖羊生产性能的影响,试验选择40只4月龄阉羊为试验动物,在冬春季节分别补饲紫花苜蓿、带穗青玉米和白三叶,试验为期4个月,然后测量各组湖羊生产性能,结果表明,与不使用青干草的对照组相比,饲喂青干草的试验组日增重、料肉比、屠宰率、出肉率、胴体内的肌肉率差异显著(P<0.05),而在3组青干草中苜蓿组的差异最显著,青玉米的效果最差(P<0.05)。说明3种青干草中苜蓿的补饲效果最好,白三叶草次之,青玉米再次之,但也远高于麦草秸秆。The purpose of this study was to investigate the effects of different types of green hay on the production performance of Hu sheep.Forty 4-monthes-old ewes were selected as experimental animals and fed with alfalfa,green corn with ears,and White Clover during the winter and spring seasons.The experiment lasted for four months,and then the production performance of each group of Hu sheep was measured.The results showed that the experimental group fed with green hay had daily weight gain,feed to meat ratio,slaughter rate,meat yield,while compared with the control group without using green hay.The difference in muscle percentage within the carcass was significant(P<0.05),while the difference in alfalfa group was the most significant among the three groups of green hay,while the effect of green corn was the worst(P<0.05).The results showed that among the three types of green hay,alfalfa had the best supplementary feeding effect,followed by white clover and green corn,but also was significantly higher than wheat straw.
