摘要
测定4月龄波尔山羊、南江黄羊、波尔山羊×南江黄羊F1代羔羊在当地饲养水平下的采食量和日增重差异.结果表明:3个品种羔羊的每周和全期青饲料日干物质采食量差异不显著(P>0.05);而在正式试验期第1周南江黄羊平均日增重显著高于波尔山羊×南江黄羊F1代(P<0.05),在第2周南江黄羊平均日增重却显著低于波尔山羊×南江黄羊F1代(P<0.05);在第3周3个品种平均日增重水平差异不显著(P>0.05),全期各品种平均日增重差异也不显著(P>0.05).说明在湘西当地饲养水平下,三品种山羊羔羊的生长性能相近,波尔山羊的杂交优势不显著.
Feed intake and daily weight gains of four-month-old goat kidlets from Boer, Nanjiang Yellow and Boer x Nanjiang Yellow F1 were studied. The results showed that daily feed intake within each week and the overall feed intake did not differ significantly among the strains （P 〉 0.05 ） ;average daily weight gains of Nanjiang Yellow kids were significantly higher than hybrid kids of Boer x Nanjiang Yellow F1 in the first week （P 〈 0.05） ;average daily weight gains of Nanjiang Yellow kids were significantly lower than hybrid kids of Boerx Nanjiang Yellow F1 in the second week （P 〈 0.05）;but in the third week average daily weight gains had no difference among the strains （P 〉 0.05）, and the overall daily weight gains had no significant difference among the strains （ P 〉 0.05 ）. The study showed that growth performance was comparable among the three strains, and the heterosis from Boer goats was not observed.
