摘要/Abstract

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.

Abstract: Feed intake and daily weight gains of four-month-old goat kidlets from Boer,Nanjiang Yellow and Boer×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×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 Boer×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.

Key words: feed intake, daily weight gains, Boer goats, Nanjiang Yellow goats, Boer×, Nanjiang Yellow F1 hybrids
