The objective of this study was to evaluate the addition of alkaloids from plants of the Papaveraceae family (Sangrovit®) and Zinc Bacitracin in the diets of broilers from 1 to 21 days of age, on intestinal morphometry (height, width, depth of crypt and height/depth ratio of intestinal villi) and performance (weight gain, feed intake, feed conversion and mortality). For this, 120 male BB chickens of the Cobb500 line were used, distributed in three treatments with five repetitions and eight animals per experimental unit. The treatments evaluated were: T1, control diet (without Sangrovit® and without Zinc Bacitracin); T2, diet with Zinc Bacitracin (500 ppm) and T3, diet with Sangrovit® (100 ppm) and with Zinc Bacitracin (500 ppm). Two phases were used for the diets, starter (1 to 10 days) with 3072 Kcal ME/kg and 21.50% crude protein and grower (11 to 21 days) with 3008 Kcal ME/kg and 19.50% crude protein. The presentation of the food was in the form of flour, offered ad libitum together with water. Live weight, daily weight gain, feed intake, feed conversion, and mortality were recorded weekly. At 21 days, five animals per experimental unit were sacrificed to collect histological samples from the jejunum and subsequently intestinal morphometry measurements were made, height, width and depth of the crypt of the intestinal villi. Data were analyzed under a Completely Randomized Design using the ANOVA procedure and Duncan's test for comparison of means. The intestinal morphometry results showed significant differences (p<0.05) for the villus width variable, being lower in T3, compared to T1 and T2. No differences were found (p > 0.05) in performance. It is concluded that the inclusion of Sangrovit® and Zinc Bacitracin has an effect on the intestinal villus width, but not on the performance of 21-day-old broilers.
