The objective of this study was to compare the effect of enramycin in broilers by evaluating the productive parameters and intestinal morphometry. A total of 800 1-day-old male chickens were used, divided into 4 treatments of 200 animals, each treatment had 8 repetitions: T1: Negative control; diet without growth promoter; T2: T1+ Bacitracin methylene disalicylate (BMD) 1kg/tn (110 ppm) for the start and 0.5kg/tn (55 ppm) for growth and finishing; T3: T1 + Enramycin 8% (Product A, 10 ppm); T4: T1+ Enramycin 8% (Product B, 10 ppm).No statistical difference was found at 42 days between the groups in any of the productive parameters under evaluation. When evaluating histomorphometry in the duodenum, no significant differences were found with respect to villus height, villus width, or area, however, the treatment where no growth promoter was used obtained a greater crypt depth compared with chickens fed with enramycin (T3). On the other hand, T3 obtained a better intestinal index. In the jejunum, the villus height was lower in the animals that were given enramycin (T3 and T4), in addition there was no statistical difference for the villus width, crypt depth, area, or the height/depth ratio. In the ileum, the height and area of villi was lower in the animals that were given enramycin (T4). The treatments with enramycin (T3 and T4) had a lower crypt depth. It is concluded that the inclusion of the enramycin did not affect the productive parameters and positively influenced the crypt depth and the height/depth ratio in the duodenum, while enramycin reduced the height of the villi in the jejunum and ileum.
