This research was carried out to investigate the effects of dietary selenium (Se) sources on hatchability traits in commercial female broiler breeders. The experimental treatment diets were: control (basal diet, none-selenium), basal diet + 0.5 mg sodium selenite (SS), basal diet + 0.5 mg Selenomethionine (S-Meth) and basal diet + 0.5 mg microencapsulated selenium (MS-Met) per kg diet. The total of 100 female and 20 roosters broiler breeder (Arbor Acres® Plus, 38 weeks of age) were considered for present experiment. Semen was collected from roosters by using abdominal massage. Incubation parameters (fertility, hatching, hatch of fertile egg, embryonic mortality, and A-grade chick) were evaluated at 44wk (younger) and 54wk (older) of age. The results indicated that the birds fed an organic sources of selenium (MS-Meth, S-Meth) the percentage of fertility and hatchability was increased (P<0.05) compared to inorganic selenium (SS) and the highest result were obtained in the birds received M-S-Meth diet. Also, the results indicated that embryonic mortality was reduced (P<0.05) in birds fed Se supplemented diet. In conclusion, the use of organic selenium supplementation in diet of could be recommended for improving of hatchability traits in commercial broiler breeders.
