The aim of the study is to conserve and characterize the Aseel germplasm, which is considered to be endangered. The birds were maintained on deep litter under a simulated backyard type of housing having night shelter and a free-range area. A total of chicks produced in the second generation from the flock collected from native tract in Andhra Pradesh was characterized for morphological, growth, production, and meat quality parameters. Aseel birds were characterized by multicolored plumage predominantly dark brown, black, golden, etc. The fertility and hatchability on total eggs were
Morphogenesis is a special process because the main organs of the chicken develop in a short time. Fertilization and early egg development in the hen The development of the chicken embryo occurs in the egg, partly in the body of the hen but mainly during the brood period after the lay. The proteins and lipids are synthesized in the liver of the hen before ovulation and are stored in layers in the egg yolk. Fertilization by the sperm of the cock can occur at that location during a short time period approximately in the first 15 minutes. Therefore, the sperm cells have to pass the whole way through the oviduct from the cloaca up to the infundibulum. The sperm cells can be stored temporarily in the vagina where selection is taking place.
