In order to study the effects of feeding time (08:00 and 14:00 hours) and frequency (once a day, twice a day and once every other day) on the performances of broiler breeder hens, two experiments were conducted with 1,248 hens of Maniker strain during 24-42 weeks (Experiment 1) and 42-60 weeks (Experiment 2) of age. No significant differences were observed in hen- day egg production and feed conversion rate between feeding times or among feeding frequencies through the entire experimental period. Mean egg weight during the age of 24-42 weeks was significantly increased by feeding in the afternoon (P0.01). But it was not significantly affected by feeding time or frequency during 42-60 weeks of age. Fertility and hatchability of eggs at 36 weeks and 60 weeks of age were not significantly different among treatments. By feeeding in the afternoon egg breaking strength at 60 weeks of age were not significantly different among treatments. By feeding in the afternoon egg breaking at 60 weeks of age was significantly improved (P0.05), but not at 36 weeks of age. In diurnal distribution of egg production, hens fed in the afternoon produced more eggs in the afternoon than hens fed during the morning (P0.01)
