【摘要】：本試驗旨在研究苜蓿草粉對波爾山羊生長性能的影響及經(jīng)濟(jì)效益分析。選取體重在24~28kg的波爾山羊母羊75只,采用完全隨機(jī)化區(qū)組設(shè)計分為5組,每組3個重復(fù),每個重復(fù)5只羊。對照組飼喂基礎(chǔ)飼糧,試驗Ⅰ組、試驗Ⅱ組、試驗Ⅲ組和試驗Ⅳ組在基礎(chǔ)飼糧的基礎(chǔ)上分別用10%、20%、30%、40%的苜蓿草粉等量替代花生秧。預(yù)試期為7d,正試期為60d。結(jié)果發(fā)現(xiàn),5組平均日采食量無顯著性差異(P0.05),但隨著苜蓿草粉替代量的增加,平均日采食量有逐漸降低的趨勢;試驗Ⅲ組和試驗Ⅳ組平均日增重顯著高于其他3組,隨著苜蓿草粉替代量的增加,平均日增重則表現(xiàn)出升高的趨勢;4個試驗組的料重比均低于對照組,其中試驗Ⅲ組和試驗Ⅳ組顯著低于對照組(P0.05),試驗Ⅳ組最低,為6.53。結(jié)果提示,波爾山羊飼糧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,苜蓿草粉替代量為40%時波爾山羊生長性能表現(xiàn)較好,但飼料成本增加。
[Abstract]:The purpose of this experiment was to study the effect of alfalfa meal on growth performance and economic benefit of Boer goat. A total of 75 Boer goat ewes weighing at 24~28kg were divided into 5 groups with 3 replicates in each group and 5 sheep in each replica using a completely randomized zone design. The control group was fed with basic diet, the experimental group 鈪，
