Abstract:
Traditional selection has led to remarkable differences in allele frequencies among various chicken breeds. Indigenous and broiler-type chicken populations were genotyped for polymorphisms in thyroid hormone responsive Spot14α , prolactin ( PRL ), IGF-binding protein 2 ( IGFBP2 ), and somatostatin ( SST ) genes in order to determine potential utilisation type-associated allele frequencies. Significant ( P 〈 0.05) differences were detected between Hungarian Yellow and broiler populations for Spot14α, PRL , and IGFBP2 allele frequencies, whereas the same SST allele (A) was fixed in both groups. In this study, the most significant associations ( P 〈 0.05) were found between the IGFBP2 genotypes and the measured traits (body weight, carcass weight, breast muscle weight with or without skin, breast muscle weight as a percentage of carcass weight) in the broiler population. The results can be applied for the evaluation of polymorphism effects in the analysed populations; however, contradictory allele effects in different breeds and hybrids indicate the need for cautious marker utilisation in selection programmes.
