Ultrasound technology was used to measure live animal meat traits instead of true carcass meat traits for beef production and cattle breeding by an increasing number of institutions. In this study, we analyzed the association between genetic polymorphisms of proopiomelanocortin (POMC) and ultrasound measurement traits in Chinese cattle. Using direct DNA sequencing in 322 individuals of 7 different cattle subpopulation, 7 SNPs were identified for genotyping within 790bp region of intron 2 and exon 3 of POMC. 6586 T>G in intron 2 and 6769 C>T and 7216 C>T in exon 3 were significantly associated with ultrasound backfat thickness (UBF) (P<0.05) and ultrasound loin muscle area (ULMA) (P<0.01) in the total population; 6694 C>T, 6706 T>C, 6796 C>T and 6810 C>T in exon 3 were significantly associated with ULMA (P<0.0001) in the total population. These results clearly suggest that these SNPs of POMC be benefit for selection of individuals with good quality meat in Chinese cattle breeding program. Following validation in other populations and breeds, these markers could be incorporated into breeding programs to increase the rate of improvement in carcass and meat quality traits.
