【摘要】:本试验旨在研究苜蓿草粉对波尔山羊生长性能的影响及经济效益分析。选取体重在24~28kg的波尔山羊母羊75只,采用完全随机化区组设计分为5组,每组3个重复,每个重复5只羊。对照组饲喂基础饲粮,试验Ⅰ组、试验Ⅱ组、试验Ⅲ组和试验Ⅳ组在基础饲粮的基础上分别用10%、20%、30%、40%的苜蓿草粉等量替代花生秧。预试期为7d,正试期为60d。结果发现,5组平均日采食量无显著性差异(P0.05),但随着苜蓿草粉替代量的增加,平均日采食量有逐渐降低的趋势;试验Ⅲ组和试验Ⅳ组平均日增重显著高于其他3组,随着苜蓿草粉替代量的增加,平均日增重则表现出升高的趋势;4个试验组的料重比均低于对照组,其中试验Ⅲ组和试验Ⅳ组显著低于对照组(P0.05),试验Ⅳ组最低,为6.53。结果提示,波尔山羊饲粮中用苜蓿草粉替代花生秧可以提高平均日增重、降低料重比,苜蓿草粉替代量为40%时波尔山羊生长性能表现较好,但饲料成本增加。
