The Effects of Turning Frequency in Incubatıon and Storage Duration on Hatching Results in Turkey Hatching Eggs

Abstract

The experiment was conducted to determine the influence of turning frequency in incubation and storage duration on hatching results in turkey hatching eggs. Hatching eggs from commercial turkey breeder farm were stored 7 d and 14 d at 17 0C and 75% RH. They were divided into turning frequencies of 12, 24 or 48 times daily. The albumen and yellow index decreased with the storage duration and was the highest in eggs stored for 7 d. The fertile hatchability (%) and the body weight of hatchling (g) decreased with the storage duration and was the highest in egg stored for 7 d. Turning frequency of 48 times daily exhibited significantly better early dead (%) The late dead (%) and the pips with dead embryo (g) increased with the storage duration and were the least in egg stored for 7 d. When the results of the study are generally evaluated, it can be suggested that hatching turkey eggs can be stored for 7 days and turned 48 times a day from 1 to 24 day of the incubation period.
