Effects of incubator oxygen and carbon dioxide concentrations on hatchability of fertile eggs, some blood parameters, and histopathological changes of broilers with different parental stock ages in high altitude.

ABSTRACT: The effects of incubator carbon dioxide (CO₂) and oxygen (O₂) concentrations with parental stock age (PSA) on embryonic deaths (ED), hatchability of fertile eggs (HFE), some blood parameters, and the tissue development of broilers were investigated. Four consecutive repetitions following the similar materials and methods were carried. From 3 different aged ROSS 308 broiler parental flocks 7,680 hatching eggs were obtained and classified as young (Y; 29 wk), middle (M; 37 wk) and old (O; 55 wk) as regards PSA, and randomly distributed. Four different incubator ventilation programs (IVP) as control (C; 0.67% CO₂ and 20.33% O₂), high CO₂ (HC; 1.57% CO₂ and 20.26% O₂), high O₂ (HO; 0.50% CO₂ and
