摘要
用5头长白公猪与15头雅南母猪杂交的51头杂交后裔测定其血清蛋白含量及估计遗传力并分析其与经济性状的相关。结果表明:长白杂交猪血清白蛋白,α-、β-和γ-球蛋白的百分含量分别是:51.92±5.44、21.48±4.2、12.09±2.11和14.86±2.11和14.86±2.31。血清白蛋白与各经济性状除屠宰率外存在显著(<P0.05)或极显著(P<0.01)的表型相关。血清γ-球蛋白的遗传力为0.790±0.353(P<0.05),饲料报酬的遗传力为0.499±0.336,两者的遗传相关为0.367±0.365(P<0.05)。血清γ-球蛋白与其它经济性状间的遗传相关也较高,且准标误较小。因此,血清γ-球蛋白可作为遗传标记应用于猪育种。
Serum protein of 51 crossbreed pigs from 5 Landrace boars and 15 Yanan sows were tested. The penotypic and genetic correlation between the percentage content of serum protein and economic traits as well as heritabilities of serum protein were estimated. The results showed that the percentage contents of serum albumin, α-, β- and γ-globin were 51.92±5.44, 21.48±4.2, 12.09±2.11 and 14.86±2.31 resp. The penotypic correlations of percentage content of serum albumin with the econmic traits except dressing percentage were all significant (p<0.05 or p<0.01). The heritabilities both of percentage content of serum γ-globin and food utilization efficiency and their genetic correlation were 0.767±0.353 (p<0.05), 0.499±0.339 and 0.76±0.365 (p<0.05) respectively. It was found that the gen etic correlations of serum γ-globin with other economic traits were also high and the standard error of the genetic correlations were lower. Hence, the percentage content of γ-globin can be regarded as one of genetic markers for swine breeding.
