Phenotypic Performance and The Characterization of Growth Hormone (GH|AluI) in Bangkok Chicken Breed

This study aimed to determine Bangkok chicken’sphenotypic characteristics and growth hormone genes using the PCR-RFLP method. The samples used were 50 chickens. Research in field is taking phenotypic traits data. laboratory carried out by DNA isolation, amplification, restriction. showed that DOC weight,body weight, bodyweight gain of DOC-1 month, 1-2 months, 2-3 months chickens significantly different (P <0.05) higher than female results molecular analysis isolation precise, then amplification GH gene fragment with a product length 997 bp restriction obtained ++ genotype. Allele frequencies genotypes chicken GH|AluI genesare monomorphic. Conclusion: average body weightgainof male was female. are
