The objective of this study was to evaluate the effect of the relationship between yacon flour or dietary copaiba oil on performance and intestinal integrity in chickens inoculated with coccidian. A total of 120 one-day old male broiler chicks (500 Cobb) were distributed in four treatments, three replicates per treatment and ten animals per replicate. The dietary treatments were: T1, basal diet (no coccidiostat); T2 (basal diet + coccidiostat); T3 (basal diet + yacon flour (0.25%)) and T4 (diet basal + Copaiba oil (0.15 ml / kg)). The evaluation period was 21 days. At day 14 were all the animals were experimentally inoculated with Eimeria. Weight gain, voluntary feed intake, feed conversion were weekly determined until the third week. At the end of the trial six animals per treatment were sacrificed and small intestine samples were taken for measurement of villus height, crypt depth, number of caliciform cells and villus height: crypt depth ratio. Furthermore, stool samples were taken for counting of oocysts / g of feces. The results showed that none of the production parameters evaluated at 14 days were significantly affected (P> 0.05) by dietary treatments. On the other hand, as to the height of villi in different segments of the intestine (duodenum, jejunum and ileum) no statistical difference was found between treatments. As for the depth of crypt, the results indicated that the supply of oil copaiba greater crypt depth (P <0.05) in the duodenum was obtained. In the ileum was observed that treatment with yacon flour scored higher number of caliciform cells (P <0.05) compared to the other treatments. On the other hand, regarding the oocyst count did not show significant difference between treatments (P> 0.05). In conclusion, unlike the supplementation with yacon flour, supplementation with copaiba oil showed to have an effect on cellular regeneration in the intestine in chickens experimentally infected with Eimeria.
