Iscan, O.
The aim of this study was to examine the effects of egg weight and extra oxygen (O2) addition into incubator at high altitude and the last stage on hatching results in turkeys. It was used 780 egg in investigation. All eggs were distributed randomly into two hatching cabinets (Çimuka Company) which were operated. The first cabinet was oxygenated at 25 % whereas no O2 added to the second cabinet between days 25 and 28 incubation and called control group. The number of chicks hatching was recorded day 28. At day 28 of incubation, all unhatched eggs were opened and examined macroscopically for the time of embryonic death. In the result of the study, albumin index an shell thickness in the egg quality characteristics, fertility (%) and hatching chick weight in hatching results, blood glucose level in hatching chicks was significantly affected by egg weight (p<0.05). Fertile hatchability (%), heart weight and (red blood cell) (RBC) in hatching chicks was significantly affected by adding oxygen in incubator at the last stage (p<0.05).
