Hormone-sensitive lipase (HSL) is responsible for the decomposition of triglycerides in adipose tissue to release free fatty acids, and it is a key rate-limiting enzyme in the regulation of adipose tissue deposition and decomposition. The objective of this study was to evaluate the association between novel SNPs in the coding region of bovine HSL gene and carcass and meat quality traits of Chinese Simmental-cross steers. Two novel SNPs were genotyped and the 47 traits of carcass and meat quality traits were measured in the population studied. Statistical analysis revealed that the SNPs of HSL gene were associated with the carcass and meat quality traits. The individuals with TT genotypes of E1-276C>T showed significant higher dressing percentage, net meat rate, hind legs circumference, fat coverage rate, mesenteric fat and kidney fat (p < 0.05). E8-51C>T (P17S) also showed a significant association with the pH of beef and fatty acids content in Chinese Simmental cattle (p < 0.01). Our findings indicated that polymorphisms in HSL might be one of important genetic factors that influence carcass yield and meat quality in beef cattle, and it may be a useful marker for meat quality traits in future marker-assisted selection programs in beef cattle breeding and production.
