This study was carried out to examine the effects of the diets containing 15.00%, 16.25%, 17.50% crude protein respectively on reproductive performance of force molted broiler breeder hens. A total of 750 Avian Ak-34 broiler breeder hens at 73 weeks old were induced to molt and fed with experimental diets between 76 to 116 weeks of age. Increasing the protein level of the diets increased egg production (%, hen-day) and daily chick weight significantly (p0.05), but not the hatchable egg weight and percentage of hatchable eggs (p0.05). Diet protein level had no significant effect on body weight and livability of hens during the experiment. Fertility and hatch of settable eggs decreased significantly (p0.01) when hens consumed more protein, while hatchability of fertile eggs were not influenced significantly (P0.05)
