摘要: The objective of this study was to investigate the effect oxygen supplementation on broiler eggs in a hatchery at high altitude growth performance and ascites syndrome broilers reared low altitude. treatment groups were with no supplemented (LA-NOX); (HA-OX); (HA-NOX) group. Growth performance, heart weight, concentrations hormones, T3, T4, T3/T4, plasma haematocrit, haemoglobin, glucose parameters during growing period investigated. A total 243 one-day-old used for study. During period, excluding days 7, 28 35, did not affect live weight compared HA-OX HA-NOX groups. cumulative feed consumption determined be lower LA-NOX group same 42nd day. Between 21 42 old, had better conversion ratio (FCR) than Chick (CW), yolk sac (YSW) chick (CHW) higher At there differences between right ventricle (RV), left septum (LV+Sept.), (TV) RV : TV ratio. T3 level T4 levels others old. hypoxic conditions that occurred embryonic stage . which altered endogenous functions prenatal chicks affected several blood parameters, improved quality. However, it improve subsequent FCR chickens when they Keywords Breeder eggs, growth, altitude,
