| Abstract | ||
| This study was established to investigate the influence of phytogenic supplementation on fertility and hatchability percentages for Broiler breeder flock. A total of 500 females and 55 males Ross 308 broiler breeders were allotted into two groups; the first received one cm of Activo@ * (specific formulation of essential oils) per liter of drinking water for five successive days each month throughout the experimental period (six months of production), while the second was a control one. 64,320 eggs were used for investigating fertility and hatchability traits throughout three production stages; the first one extended from the 6th to the 13th week, the second was extended from the 14th to the 21st week and the third stage extended from the 22nd till the 29th week of laying. Phytogenic supplementation significantly improved fertility and hatchability percentages (scientific and commercial) as well as the weight of hatched chick. Uunhatched and culled percentages were significantly declined especially those of early stages of production. Meanwhile there was none significant influence on embryonic mortality, piped live and dead percentages. Supplementation of essential oils to broiler breeders' flocks during early stages of production is recommended. | ||
