Incubation Yield as a Function of Broiler Breeder Age

Abstract: The factors involved in poultry egg incubation include breeder hen age, which may influence both the external and internal quality of eggs. In this context, this study sought to determine incubation yield among eggs from breeder hens at three ages. A total of 1,728 eggs were obtained from Cobb broiler breeders at three ages (26 weeks, 32 weeks, and 53 weeks) and incubated. At the end of the incubation process, eclosion, hatchability, the percentage of infertile eggs, the time of embryo mortality, and chick wei… Show more

“…The high index of ENCH and EDE may be a factor in egg quality, which according to previous studies, can be influenced by the age of the layer (Araújo et al, 2017;Jabbar & Ditta, 2017;Silva et al, 2017;Okur et al, 2018;Gharahveysi & Kenari, 2018). Old layers produce thin egg shells, which easily crack.…”
