子午岭野猪不同杂交组合生长性能比较研究

Comparative Study on Growth Performance of Different Hybrid Combinations Based on Ziwuling Boar

为对野猪资源的开发利用提供依据,笔者选用子午岭野猪为父本,杜洛克猪、长白猪、大白猪为母本,设置3个杂交组合。对各组试验猪的平均日增重和料肉比做了对比试验,试验结果表明:子午岭野猪与杜洛克猪、长白猪杂交一代的平均日增重明显高于子午岭野猪与大约克夏猪杂交一代的,3个杂交组合的料肉比差异不显著。

Three hybrid combinations were established selecting Ziwuling boar as male parent, three swine breeds Duroc, Landrace and Large White pig as female parent in order to develop boar resources. Average daily weight gain and feed gain ratio were measured, the results indicated that average daily weight gain of F1 from Ziwuling boar hybriding Duroc and Large White pig was significantly higher than Flfrom Ziwuling boar hybriding Landrace, feed gain ratio was nonsignificant difference.
