AbstractThe effects of timing, the amount and the frequencies of feeding on the performance of broiler breeders(Ross 308) at the age of 31-38 weeks were studied. The broiler breeders were randomly assigned to eachof 15 treatments (T). These included once a day feeding, in which birds were fed once at 04:00 h(T1=control), twice (T2 to T7), thrice a day (T8 to T13) and four (T14 and T15) times per day. The dailyfeed allotment was divided into different ratios with different time schedules. The nutritional compositionof all experimental groups was similar. Eggs were collected at 8 a.m., 10 a.m., 2 p.m. and 4 p.m. Theresults obtained showed that feeding schedule resulted in significant differences (p<0.05) in eggproduction (% hen), as well as the fertility and hatchability. Results obtained in our study suggest thatallocation of restricted feed 2 times a day, in a 75:25 ratio (4 a.m. and 12 o’clock) improved eggproduction, fertility and hatchability.
