Abstract :
Melanocortin-4 receptor (MC4R) gene has been known as a candidate gene for growth traits in livestock. This research was aimed to identify the polymorphism of MC4R gene and its association with growth traits in Sumba Ongole (SO) cattle. The growth traits data consist of body weight and body size. Eighty four blood samples were collected and used for DNA isolation. The results showed one SNP (g.1133C>G) resulting in two alleles (C and G) and three genotypes (CC, CG, and GG) in SO cattle. The frequency of G allele (0.59) was higher than C allele (0.41). The CG genotype had the highest value of genotype frequency (0.48). The allele and genotype distributions followed the Hardy-Weinberg equilibrium. The single nucleotide polymorphism (SNP) g.1133C > G revealed having no significant association with growth traits in SO cattle. In conclusion, the SNP g.1133C > G may not useful as selection tool in Sumba Ongole cattle. It can be suggested that the future study is needed to find out the effect of the MC4R gene in Sumba Ongole cattle in different locus.
