The objective of the present study was to evaluate the effect of enramycin on carcass and breast yield, immunocompetence and intestinal integrity in broilers. In this experiment, 800 1-day-old male BB chickens were used, which were randomly distributed among 4 treatments with 8 repetitions each, the treatments used were: T1: basal diet, T2: T1 + Bacitracin Methylene Disalicylato (BMD)11% (1kg/MT (110 ppm) for the beginning and 0.5kg/tn (55 ppm) for growth and finishing), T3: T1 + Enramycin 8% (Product A, dose 125g/MT (10 ppm)) and T4: T1 + Enramycin 8% (Product B, dose 125g/MT (10 ppm)). The diets were supplied ad libitum, which were divided into three stages: AABB Start (1 – 21 days), AABB Growth (22 – 35 days) and AABB Finish (36 – 42 days). The samples to evaluate the yields of carcass, breast and immunocompetence were taken at 42 days and the samples for the evaluation of the intestinal integrity were taken at 35 and 42 days. Registered data were submitted to analysis of variance using a Completely Randomized Design and for mean comparison Duncan Test was employed. The results showed that the use of enramycin did not affect (P ˃ 0.05) carcass yield, breast yield and immunocompetence at 42 days. The use of enramycin influenced (P ˂ 0.05) the intestinal health score. Intestinal integrity parameters: cecum weight, intestine weight and intestinal length were not affected (P ˃ 0.05) by the use of enramycin at 35 and 42 days. In conclusion the use of enramycin did not affect carcass yield, breast yield, immunocompetence and intestinal parameters such as cecum weight, intestine weight and intestinal length.
