Milk production is one of the most desirable traits in livestock. Recently, the Toll-like receptor (TLR) has been identified as a candidate gene for milk traits in cows. So far, there is no information concerning the contribution of this gene in milk traits in sheep. This study was designed to investigate the TLR 4 gene polymorphisms in Barki ewes in Egypt and then correlate that with milk traits in order to identify potential single nucleotide polymorphisms (SNPs) for these traits in sheep.

Toll样受体4（TLR4）基因编码区的错义突变会影响Barki绵羊的乳性状。

牛奶生产是牲畜最可取的特征之一。最近，Toll样受体（TLR）已被确定为奶牛性状的候选基因。到目前为止，尚无有关该基因在绵羊乳性状中的作用的信息。本研究旨在调查埃及Barki母羊的TLR 4基因多态性，然后将其与牛奶性状相关联，以鉴定绵羊这些性状的潜在单核苷酸多态性（SNP）。
