Abstract :The effects of supplementing broilers` diets with fermented cottonseed meal insert ignore into journalissuearticles values(FCSM); on the broilers` performance, apparent digestibility, carcass traits, and meat composition were studied. A total of 180 yellow-feathered chickens of 21 days old were randomly divided into three groups insert ignore into journalissuearticles values(six replicates of 10 broilers each);: 1); a control group insert ignore into journalissuearticles values(Con);, 2); a treatment group of FCSM by Candida tropicalis insert ignore into journalissuearticles values(Ct);, and 3); a treatment group of FCSM by C. Tropicalis plus Saccharomyces cerevisiae insert ignore into journalissuearticles values(Ct-Sc);. Results showed that FCSM supplementation improved the average daily gain and gain-to-feed ratio from the 43rd to 64th and the 21st to 64th day, respectively insert ignore into journalissuearticles values(P < 0.05);. The dietary nutrient digestibility of dry matter, crude protein, and crude ash significantly increased insert ignore into journalissuearticles values(P < 0.05); with FCSM supplementation. The abdominal fat content was lower insert ignore into journalissuearticles values(P < 0.05); in Ct and Ct-Sc than in Con insert ignore into journalissuearticles values(21st to 42nd day);. The crude protein content was higher in the thigh muscles of treatment groups and breast muscles of Ct, and the crude fat insert ignore into journalissuearticles values(ether extract); in the breast muscles of Ct-Sc was higher than in Con throughout the entire duration insert ignore into journalissuearticles values(P < 0.05);. In conclusion, FCSM is beneficial for broilers as it positively affects their growth and digestibility in addition to altering their meat compositions.
