Abstract EN
This experiment was conducted at Kharabo farm, Faculty of Agriculture, University of Damascus.
A total of 252 chicks of Japanese quail breeder females were distributed on the first day of life into two groups, Gicks in G1 were reared from 1-28 days of age under ideal required temperature according to their age, while chicks in G2, were subjected to heat stress from 8 am to 5 pm at 42 °C from the first day of hatching until 28 day of age and to the ideal required temperature from 5 pm until 8 am.
Chicks of each group were distributed into three subgroups, with three replicates per subgroup.
Vitamin C was added to the drinking water for replications at the concentrations of 0 (the control subgroup), 10, 20 g/L in order to study the impact of heat stress and vitamin C supplementation on fertility and hatchability.
Results indicated that heat stress during rearing period led to significant differences in the percentages of fertilized eggs and hatching between stressed and non-stressed birds when vitamin C was added at a concentration of 10 g/L.
in favor of stressful group (16,7 and 25%, respectively).
It was also found that there were significant differences between the two groups regarding fertility and incubation percentages in favor of unstressed birds (9.4%, 13.4% respectively.
Adding vitamin C with 20g/L.
led to a significant difference in the fertility percentage with greater value showed by unstressed birds (6.6%).
