An experiment was conducted to evaluate the effects of Wheat, Sodium bentonite and Amet on pellet quality and broiler performance. Eight experimental diets were pelleted in a 2×2×2 factorial combination with two levels of wheat (0 and 10%), Sodium bentonite and Amet (each 0 and 1.5%) as pellet binder. In first experiment, to evaluate of pellet quality, pellet durability index was measured in six samples of each experimental feed pellet in feed factory and farm. In second experiment, 864 Ross-308 strain broilers from 11 to 42 days old were assigned in to eight treatments and three replicates to study their performance. In starter diet wheat increased, and Amet decreased significantly pellet quality in farm )P0.05(. Sodium bentonite in finisher diet decreased pellet quality in feed factory and farm, but Amet increased pellet quality in feed factory )P0.05(. Sodium bentonite improved significantly weight gain and feed conversion ratio and declined mortality rate in period of 11 to 21 days old )P0.05(. Sodium bentonite decreased percentage weight of gizzard and thigh, but Amet increased only on percentage weight of gizzard )P0.05(. It can be suggested to feed factory using 10 percentage Wheat, 1.5 percentage Sodium bentonite and 0 percentage Amet in pelleted feed, because it can improve pellet quality in farm, feed conversion ratio and weight gain.
