Marbling is one of the most important beef quality traits. An association between a non-synonymous variant located in EGFLAM (EGF-like fibronectin and laminin G) and marbling in Hanwoo cattle has recently been published. We therefore investigated the association between this SNP (rs109436056 SNP) and marbling in Limousin cattle. A total of 355 animals were phenotyped for marbling and genotyped for this SNP. Significant association (p < 0.05) was observed, in which genotype CC exhibited higher marbling. This SNP could be used for the genetic improvement of marbling in Limousin cattle.
大理石花纹是牛肉最重要的质量特征之一。最近已经发表了位于 EGFLAM（EGF 样纤连蛋白和层粘连蛋白 G）中的一个非同义变异与韩牛大理石花纹之间的关联。因此，我们研究了该 SNP(rs109436056 SNP)与利木赞牛大理石花纹之间的关系。总共对 355 头动物进行了大理石花纹表型分析和该 SNP 的基因型分析。观察到显著的关联（p < 0.05），其中 CC 基因型表现出更高的大理石花纹。该 SNP 可用于利木赞牛大理石花纹的遗传改良。
