Abstract: | Indonesia local chickens have genetic potency with high ecomonic value such as meat and egg production, adapted in tropic and strong immunity. The chicken growth hormone (cGH) gene has a crucial role in controlling growth and metabolism, leading to potential correlations between cGH gene polymorphism and economic traits. This study aimed to identify the cGH gene polymorphism and find out the variation of gene at several local chickens, the crossbred, commercial meat type and layer. Polymorphism in intron 4 of cGH gene was studied in 229 chicken blood samples consisted of kampung, pelung, sentul, commercial meat type, layer, merawang, commercial meat type x kampung, kampung x commercial meat type, sentul x kampung and pelung x sentul chickens. A specific primer set was used to amplify a fragment of growth hormone locus using PCR. PCR products were digested with MspI restriction endonucleases. The amplified fragment digested with MspI enzyme revealed 2 alleles A and B with the frequency of 0.88-0.96 and 0.04-0.12, except in layer chickens only had 1 allele A with the frequency of 1.00. The results showed that cGH gene in MspI locus at kampung, pelung, sentul, commercial meat type, merawang, commercial meat type x kampung, kampung x commercial meat type, sentul x kampung and pelung x sentul chickens were polymorphics, except the layer chickens was monomorphics. The population of Indonesia local chicken and the crossbred that was studied in this research had low heterozygosity value but it was still in the Hardy-Weinberg equilibrium. |
