摘  要:
为了研究磷酸甘油酰基转移酶5(AGPAT5)基因与德系西门塔尔牛肉质性状的相关性,试验采用PCR-RFLP方法对AGPAT5基因的多态性进行检测,并利用SPSS软件对所检测到的多态性位点与德系西门塔尔牛的肉质性状进行相关性分析。结果表明:AGPAT5基因第3内含子上存在G→C突变;统计分析结果显示,该位点的多态性与德系西门塔尔牛的出栏重、宰前重、胴体重和净肉重呈显著相关(P<0.05),而对其他性状的影响差异不显著(P>0.05)。

摘  要:
To study the correlation between the polymorphism of AGPAT5 gene and meat quality traits in German Simmental cattle,the PCR-RFLP method was used to detect the polymorphism of AGPAT5 gene,and then the correlation between the locus containing polymorphism and the meat quality traits of German Simmental cattle was analyzed by SPSS software.The results showed that there was a single point mutation(G→C) in intron3.The statistical analysis showed that the polymorphism of the locus was significantly correlated with slaughter weight,before slaughter weight,carcass weight and meat weight of German Simmental cattle(P<0.05).While there were no significant differences in the other traits(P>0.05).
