Abstract

This study aims to examine the impact of adding chitosan and probiotics to the diets of broilers oon the carcass characteristics of broilers. A total of 144 broiler chicks from Ross 308 were used in this study. They were of average weight (43 g). They were divided into 6 treatments with 3 replicates (8 per treatment). The first treatment was without any addition (control treatment), the second was adding 1 g/kg of probiotic, he third was adding 0.5 g/kg of chitosan, the fourth was adding 1 g/kg of chitosan, the fifth was adding 0.5 g/kg of chitosan plus 1 g/kg of probiotic and the sixth was adding 1 g/kg of chitosan plus 1 g/kg of probiotic. The foundation of this studywere significant differences (P≤ 0.05) in the percentage of carcass refining and superiority of the third treatment, but there were no significant differences in the relative weight of the main cuttings and the relative weight of the secondary cuttings of carcass. For the internal organs (heart, gizzard and liver), there were significant differences (p ≤ 0.05) in the relative weight of the heart, and the superiority of the fifth treatment. As for the relative weight of the gizzard, the third treatment was significantly superior (p ≤ 0.05). The fourth treatment was significantly superior (p≤0.05) to the rest of the treatments for the relative weight of the liver. There were no significant differences in the relative weight of uneaten viscera.
