The impacts of feeding time on the performance of broiler chicks at 28,35 and 42 days has been proceeded.

A total 120 one day old broiler chicks (Ross 308) were reared on feed having 21.8% protein and 3049 kcal metabolizable energy/kg for 14 days.

At the beginning of the third week, the chicks were assigned to four treatments through four grops.

Each group contains 30 chicks and have three replieates.

The first group (T1) was fed ad libitum and considered as control, while the second group (T2) was fed at 3.30 pm (once daily for 1 hour).

The third group (T3), was fed at 8.30 pm (once daily for 1 hour) and the fourth group (T4) was fed at 3.30 and 8.30pm.

Four chickens had been slaughtered (2 male and female) aged 28, 35 and 42 days for each replicate in each treatment.

Per slaughter live weight, the weights of the carcass and weights of each of the breast, thigh, wings, heart, liver and gizzard and finally the legs were taken away proportion of dressing, breast, thigh, wings, heart, liver and gizzard and attributed to the weights of the carcass and extract Alenci percentage legged forgotten weight to the neighborhood.

The result revealed that no significant differences were noticeable in the final body weight, carcass weight and dressing proportion at 28<35 and 42 day of age.

At, 35d, group 2had superior (P≤0.05) breast proportion yields and control had superior (P ≤0.05) heart Percentage.
