【摘要】 (目的)研究ACSL1基因在日本和牛与中国西门塔尔牛的杂交牛中对肉质性状的影响。(方法)采用PCR扩增测序检测得到不同基因型,同时检测个体的肉质性状,进行统计分析。(结果)在本群体中,基因型只检测到GG与CG型,其中GG型基因型频率为64.29%,CG基因型频率为35.71%,G的等位基因频率为82.14%,C的等位基因频率为17.86%。在不同基因型效应的影响下,阉牛与未阉公牛之间在弹性与咀嚼性上存在显著差异(P<0.5)。(结论)在ACSL1基因效应影响下阉牛与未阉公牛肉质存在差异。更多还原

【Abstract】 (Objective) the study aimed at analysis of effect of mutation of ACSL1 gene on meat quality traits in Chinese Simmental and wagyu hybrid cattle.(Method) the different genotypes were checked in cattle populations by sequencing, and phenotypic value on meat traits was got for statistic analysis.(Results) genotypes of GG and GC were detected, and genotype frequency of the former is 64.29%, the latter 35.71%.allele frequency of G is 82.14%, and C is 17.86%. Elasticity and chewiness were significantly different between bull and bullock(p<0.05).(Conclusion) meat traits based on effect on ACLS1 gene were significantly different between bull and bullock(p<0.05).更多还原
