Growth Hormone Gene Polymorphism and its Relation to Quail Growth and Carcass

Abstract

In this study, it was aimed to determine the polymorphism of GH (growth hormone) gene in Japanese quails and the relationships between these genes and body weight and carcass traits. 3 genotypes (AA, AB and BB), 2 (A and B) alleles were detected by cutting the GH intron 1 region with restriction enzyme MspI. As a result of variance analysis, it was determined that the hatching weights of the animals with B allele and liver weights were higher. Thus, it is seen that GH gene and PCR-RFLP technique can be used in breeding studies.
