Removing of Japanese Quail Males in Heat Stress Conditions

M. Yerturk, M. Avci and O. Kaplan    

Abstract: This experiment was carried out to determine the fertility performance and duration of fertility in the eggs laid after removing of male from cage reared under heat stress in the Japanese quails. In the study, 24 male and 72 female quails at 6 weeks of age were randomly divided into two groups (control and trial). Trial group was kept at high ambient temperature (33-42°C) and control group propagated in a 17-25°C environmental condition. The effects of heat stress on feed consumption, feed efficiency, egg production, egg weight were decreased. Also fertility ratio of the eggs laid after third day of removing of male were reduced (p<0.01). However, hatchability of fertile eggs and embryonic mortality were not statistically significant. As a result, the eggs laid after fourth day of removing of male in a high environmental temperature should not be incubated because of low fertility ratio.
