为研究青贮蚕豆秸秆对山羊生产性能和饲养经济效益的影响，本试验选用80头健康育肥公羔（波尔×黄淮），随机分为4组，每组2个重复，每个重复10只公羔，对照组饲喂基础日粮，试验1、2、3组分别以青贮蚕豆秸秆代替20%、40%、60%的稻草-玉米秸秆粗饲料，试验期60 d。结果表明，与对照组相比，试验第2组育肥公羔日增重提高了18.23%（P＜0.01），料重比降低了11.72%，经济效益提高了27.21%；试验3组育肥公羔日增重提高了7.39%（P ＜0.01），料重比降低了5.50%，经济效益提高了8.26%。综上所述，以青贮蚕豆秸秆部分替代稻草-玉米秸秆能够改善育肥公羔的生产性能和提高饲养经济效益，替代量为40%效果最佳。%To study the effect of silage fresh been straw on growth performance and raising economic benefit of goats. A total of 80 fattening goats (Boer×Huanghuai) were chosen and randomly divided into 4 groups with 2 replicates of 10 each.The control group was fed with the basal diet,and group 1,2,3 were fed with the basal diet of 20%,40%,60%straw-corn stalks roughage replaced by silage fresh been straw.The experimental period lasted for 60 days.The results showed that,compared to the control group,the average body weight gain of group 2 was increased by 18.23%,feed con-version ratio was decreased by 11.71%,and economic benefit was increased by 27.21%;the average body weight gain of group 3 was increased by 7.39%,feed conversion ratio was decreased by 5.50%,and economic benefit was increased by 8.26%.In conclusion,silage fresh been straw instead of the straw-corn stalks roughage could improve the production per-formance and raising economic benefit of goats.The effect of 40%straw-corn stalks roughage replaced by silage fresh been straw was the best.
