The objective of this study was to evaluate the zootechnical performance and yield of Ross 308 AP chickens according to different feeding programs. 2400 day old chicks were used, they were housed in a controlled environment, a randomized block design was used, with 4 treatments of 12 repetitions with 50 birds each. Treatment 1 corresponded to the program currently practiced by the company, treatment 2 was the program recommended by the genetic line, treatment 3 corresponded to a new feeding program, equivalent to the average of the suggested consumption for treatments 1 and 2, the treatment 4 control, food was supplied ad libitum. The evaluated performance characteristics were: Food consumption (gr), Weight gain (gr), feed conversion (g / g) and Mortality, weight of the birds and feed consumption was recorded on day 7, 14, 21 , 28. 35 and 41 of age, mortality was recorded daily for the respective consumption corrections. At the end of the productive cycle, the performance of the carcass, breast and leg was assessed. The data were subjected to analysis of variance and tukey test to observe difference between treatments. At day 41, the feed intake was significantly lower (P <0.05) for T1, however, in the other parameters evaluated there were no statistical differences. It is concluded that the increase of the daily food supply did not improve the zootechnical performance nor the performance of Ross 308 AP chickens.
