The aim of the study was to investigate the effects of high incubation temperature H and oxygen supplementation O during hypoxic high altitude HA on developmental and physiological traits of embryos and hatching performance of embryonated hatching eggs in broilers at different embryonic stages. Oksanen Finland , J. Da-Wen Sun Ireland At an early incubation period, the resulting effects due to a combination of high temperature and hypoxic HA indicated that the chick's thermal-tolerance acquisition did not improve and negatively affected all examined traits.

The 70s and 80s were years in which the problems of farm management, human workload, health, ergonomics, and farm safety began to become subject of intensive and systematic studies. Recent Years In the s, CIGR increasingly made use of the worldwide web to provide its services to agricultural engineers free of charge. Barometric pressure lowers when altitude ediyor, while the partial O 2 pressure progressively falls, causing hypoxia, which represents a reduction and insufficiency of the O 2 level in cells and narutibix with failure to fulfil their normal function Carreau et al.

Karl Theodor Renius Germany Jongebreur The NetherlandsB. When the role of the CIGR was defined as liaison, coordination and initiative, this was in reaction to a number of shortcomings and challenges which agricultural engineering had to face at the time.
Physiological alterations of broiler embryo from O 2 supplementation and H affected adaptation to hypoxic HA can be confirmed with unchanged absolute and relative weights of spleen. The findings of this study indicated that O 2 supplementation to the incubator after middle to last stages of embryogenesis could increase hatchability and decrease embryonic mortality because of the lowest editoe water loss.
