Abstract

The aim of the current research was to evaluate a comparison of the effects of ASRI1, ASRI2 and Optifeed (commercial growth promoter) and prebiotic lactose (0 and 1 kg/ton of diet) on performance and small intestinal morphology of broiler chickens. A total of 750 Arian chicks were used in a completely randomized designed as 3*2 factorial including six treatments, five replicates and 25 birds per each pen (mixed of male and female). Diets was formulated for three periods of 0-14 d, 14-28 d and 28-42 d. The result showed that herbal growth promoters and prebiotics could not effects on body weight and feed intake. FCR and the weight of burs fubresius were significantly decreased in ASRI2 compared to other two growth promoter. prebiotic reduced the carcass percentage, neck and back and increased the abdominal fat. The main effects of growth promoter, prebiotic and their interaction on the relative weight and length of intestine tracts and morphological were not significant. There was not difference between ASRI1, ASRI2 and Optifeed, so commercial imported growth promoter can be substituted by ASRI1 and ASRI2 products.
