An experiment was conducted to evaluate the impact of different levels of commercial Y-MOS yeast on performance, carcass characteristics and meat quality of broiler chickens. The Complete Randomized Design was used. A total of 300, unsexed one- day old (Ross 308) broiler chicks were randomly divided into four dietary treatments. The treatments contain 0, 1.0, 1.5 and 2 kg Y-MOS/ton of feed. Each treatment was sub-divided into three replicates; with each having 25 experimental birds. All diets were formulated according to (NRC) to meet the nutrient requirements of the broiler chickens. The results showed that all parameters values of performance (body weight, feed intake, body weight gain and feed conversion ratio) were not affected significantly (P>0.05) by the Y-MOS yeast supplementation to diets fed to broiler chickens throughout the experimental period. The results revealed that there were no significant (P>0.05) differences in dressed carcass, muscle: bone ratio, commercial sale cuts (breast, thigh, drumstick and wing) and none-carcass components among treatment groups of broiler chickens. However, results showed that there was significant (P<0.05) differences among all treatment groups in chemical composition and physical properties of broiler breast meat.
