The aim of this study was to investigate the association of the , and single-nucleotide polymorphisms (SNPs) of the bovine () gene with milk yield and quality traits in Holstein cattle. For this purpose, 166 Holstein dairy cows were genotyped for these three SNPs. Correlation analyses showed that the SNP was associated with 305-day milk yield ( < 0.05). Besides, SNP was found to be associated not only with 305-day milk yield but also with milk fat, milk quality traits, somatic cell score, electrical conductivity and pH ( < 0.05). The results of this study suggest that the and SNPs could be used in breeding for the improvement of milk yield and milk quality in cattle. Furthermore, based on its association with mastitis related traits, the SNP was considered as a potential indicator of mastitis susceptibility.
本研究旨在调查牛β-酪蛋白（CSN2）基因的rs10490955、rs41419388和rs13674855单核苷酸多态性（SNP）与荷斯坦奶牛产奶量和乳品质性状之间的关联。为此，对166头荷斯坦奶牛的这三个SNP进行了基因分型。相关性分析表明，rs10490955 SNP与305天产奶量相关（P<0.05）。此外，发现rs41419388 SNP不仅与305天产奶量相关，还与乳脂肪、乳品质性状、体细胞评分、电导率和pH值相关（P<0.05）。本研究结果表明，rs10490955和rs41419388 SNPs可用于牛育种，以提高产奶量和乳品质。此外，基于其与乳腺炎相关性状的关联，rs13674855 SNP被认为是乳腺炎易感性的潜在指标。
