Chicken growth hormone and its receptor are considered one of the very important somatotropic hormones because of their crucial role on the body growth and cell proliferation. This work explain the important relation between molecular genetic and avian physiology, and the benefit of their interaction on the modern flocks selection program. This modern selection program lead to decreased time and funds throw early detection of the best genotype and isolate it. This technique is very important in avian artificial insemination throw using one or two males in artificial fertilization for hundreds of hens and get best results at less time. Finally the joining between molecular genetic and avian physiology lead to many advantage for breeders.
