Al-Ghadi Journal of Animal and Plant Sciences JAPS 20182018/02/01 28 1 73-79 1018-7081 NA <p>We evaluated some natural products to compare their effects against a synthetic anticoccidial drug in an induced Eimeria spp. infection in broiler during the finisher stage. On day 15, a total of 200 birds (Ross 308) were randomly distributed into 10 treatments. Birds were infected with&nbsp;<em>Eimeria spp.</em> in the positive control and treatment groups. The results indicated that feed intake, body weight and feed conversion ratio (FCR) did not differ significantly (P&gt;0.05) between synthetic anticoccidial drug and natural products. Challenged birds had longer small intestines and heavier liver as compared to unchallenged birds. Lesion score and oocysts secretion increased significantly (P&lt;0.05) in the challenged birds, however, synthetic anticoccidial drug had no significant (P&gt;0.05) difference with the natural products. It was concluded from the present study natural products are very effective in comparison with anticoccidial drug to control coccidiosis in broiler chicken.</p> coccidiosis, broiler, drugs, natural products, control Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=2018-JAPS-10
