This study was conducted to investigate the effects of lighting and feeding time management (at morning or afternoon) on productive and reproductive performance of Japanese quail in the hot summer of Assiut. Two hundred and forty unsexed one-day old chicks were reared in batteries and assigned to 4 groups (60 birds /each). The birds of first and second groups (C and T1), were exposed to light at the morning (1000 to 2200) and fed twice daily at 1000 and 1600 h as well as 2200 and 0400 h, respectively. The third and fourth groups (T2 and T3) were exposed to light at the afternoon (2200 to 1000) and fed twice daily at 1000 and 1600 h as well as at 2200 and 0400 h, respectively. All the other conditions were the same during the experimental period. Birds were supplied with clean water all the time. The results showed that change feeding and lighting time to afternoon significantly (P≤0.05) improved growth performance, body temperature, egg number, egg quality and fertility percentage. While, no significant differences (P≤0.05) existed in hatchability, egg weight and egg components. In conclusion, feeding Japanese quail at afternoon coincide with light is a good and economical managerial tool to alleviate the harmful effects of high temperature stress during the summer season at Assuit.
