摘要
利用湖北Ⅵ系继选育群1990~1997年生长和胴体性能测定资料,对湖北白猪生长及胴体性状的遗传参数进行了估计。结果表明:遗传力的估计范围内,生长性状各组分间表现为较强的相关关系(P<0.05或P<0.01)胴体性状各组分间表现为中到低的相关关系。通过相关关系分析得出生长性状应注重和6月龄重的选择,胴体性状表现为多基因或基因组控制且之间的交互作用大,应采取综合性状选择。
Based on the data of
growth and cacass performance of Hubei white pigs line measured during 19901997, the
genetic parameters of growth and carcass traits of Hubei white pigs line were estimated. The
results show that almost all estimated values heritability were within the reported range.
There was fairly strong correlations between the components of growth trait(P<0.05 or P<0.
01). Most correlations between the comonents of carcass trait were moderate or low. Using
correlation analysis we can know:The selection of growth trait should focus on the selection of
the body weight at 2 and 6 months; Carcass traits are controlled by polygene or the whole
genome and the interaction effects between components are large, synthetical traits
selection should be adopted.
