ABSTRACT: 180 day- old broiler chicks were used in a study designed to evaluate the effects of different levels of feed restriction at the growing period on the physiological response and performance of broiler chickens under the humid tropical conditions of hot season. The experiment consisted of four quantitative feed restriction treatment groups, each in three replicates of 15 birds per replicate. The treatments indicate the proportion of total daily allowance of feed restricted and offered to groups: T1 (0%), T2 (15%), T3 (30%) and T4 (45%). The experiment was framed in a Completely Randomized Design and was conducted in the hot season (April, May and June). Feed was restricted during the third, fourth and fifth weeks of age. Blood samples were collected from three birds in each of the....
