Study of the influence of light on the egg production of the female Japanese quails was conducted. Three hundred Japanese quails of 3 weeks old were randomly allocated to five groups, and four replicates for each group. All quails were fed with the same completed feed which contained 24 and 20 percent protein for birds aged 3 to 5 and 6 to 46 weeks respectively. Each group received the day length at different levels 24, 21, 18, 15 and 12 hours per day. The results indicated that the supplement of light at 21 hours per day showed the best performance, the average number of egg per quail was 241 egg, egg production was 86 percent the feed conversion ratio (FCR) was 2.1 and feed cost per egg 1 kg was 19.8 bath respectively. The other groups that received the light supplement at level 18, 15, 24 and 12 hours per day show the lower performance respectively.
