Experiments was carried out to determine the effect of protein level on the egg production of Japanese quails. The first phase was carrying on the 3-weeks old quails. The total number of 720 quails containing an equal number of male and female were divided into 5 groups and 4 replications per group. Each replication contained 18 males and 18 females and allotted into 5*2 Factorial in CRD. The mixed formula feed varying protein content as 20, 22, 24 and 26 percent were used for feeding of each small group during the age of 3-6 weeks respectively. The completed formular feed which contained 23 percent protein was used as a standard formula feed. the results obtained that the group which was fed which was fed with 26 percent protein feed showed the best feed conversion ratio and the average daily gain was 2.7 gram per day. It was also found that the female quails showed better average daily gain (ADG), feed conversion ratio (FCR) and cost of production than the male quails significantly (P0.01). The second phase was continuing on the 270 female quails of 6 weeks old. The group was allotted into CRD and divided into 5 groups according to the same 5 rations of the first phase. All quails were fed with the mixed feed containing 20 percent protein and 3,000 Kcal/kg or ME. After 6 to 12 weeks, the results obtained that the birds prefed with 26 percent protein feed showed the best average number of egg, percentage of egg production, feed conversion ratio and cost of production.
