Abstract
This study was performed to find the effect of some natural products (Cozante, Norponin and Organimix) in comparison to standard anticoccidial drug (Elancoban) in experimentally induced coccidiosis in broiler. A total 200 birds (Ross 308) were randomly assigned to 10 treatments on day 15 after introduction of coccidiosis. The results indicated that feed intake and production efficiency factor (PEF) did not differ significantly (P>0.05) between Elancoban and natural products. However, treatment had a significant effect on BWG and FCR (P<0.01 and P<0.001, respectively), chicks which had received Elancoban had the highest BWG (327.9 g) and converted the feed to gain with highest efficiency (1.444 g: g). Challenged birds had longer small intestines and heavier liver as compared to unchallenged birds. Lesion score and oocysts secretion increased significantly in the challenged birds, however, Elancoban had no significant difference with the natural products. It was concluded from the present study that natural products could be effective in comparison with anticoccidial drug to control coccidiosis in broiler chicken.
