Based on a completely randomized design, 240-day-old chickens were randomly divided into six experimental diets and four replications with 10 chickens each. Experimental diets consisted of corn-based diet (CBD) (T1), WBD with routine am ounts of vitamin A (9000 IU kg -1 ) (T2), T2 without vitamin A in premix (T3), T2 + 6000 IU kg -1 vitamin A (T4), T2 + 420 IU kg -1 xylanase (T5), and T2 + 6000 IU kg -1 vitamin A + 420 IU kg -1 xylanase (T6). For Feed Conversion Rate (FCR) between day 1 and 21 and between day 21 and 42 WBD supplemented with vitamin A and enzyme was less than CBD (p < 0.05). Also, supplementation of surplus vitamin A singly, and vitamin A and enzyme improved digestibility of crude protein (CPD) and crude fat (CFD) than WBD with routine amounts of vitamin A (p < 0.05). The villus (duodenum, jejunum and ileum) was longer (p < 0.05) in broilers fed on diet supplemented with vitamin A and enzyme than those with CBD. It may be concluded that enzyme and vitamin A supplementation to WBD may improve mentioned parameters. 2014 artículo científico 1806-2636 https://www.redalyc.org/articulo.oa?id=303132001007 en http://www.redalyc.org/revista.oa?id=3031 Acta Scientiarum.
