摘要
Pro-opiomelanocortin (POMC) plays an important role on animal ingestive behavior and energy homeostasis. Genetic variation of POMC was detected by PCR-SSCP and DNA sequencing techniques in 480 individuals from seven cattle breeds (i.e., Qinchuan, Nanyang, Jiaxian Red cattle, Jinnan, Luxi, Angus, and Chinese Holstein), and association analyses were carried out to evaluate the effects of genotypes of the candidate genes on growth traits in Nanyang cattle. Three SNPs (811845 C>T, 811821 T>C and 811797 A>G, ref. NW_928357) in linkage were detected in P3 locus, which were located at the 3' flanking region of bovine POMC gene. The body weight at 6-month-old and the average daily gain of 0~6-month-old were higher in Nanyang cattle with the genotype BB than with the genotype AA (P<0.05).
