Avian coccidiosis is considered among the infectious disease of high costs in the poultry industry. Herbal extracts are safe and reliable substitute anticoccidial drugs for chemical feed additives as they don’t sequel to drug resistance and tissue remnants. The purpose of the current study was to assess the anticoccidial effect of an herbal complex of 3 plants (Artemisia Annua, Quercus infectoria, and Allium Sativum) in broiler chickens in comparison with toltrazuril anticoccidial. One hundred twenty broiler chickens were used in this experiment and divided into 4 equally numbered groups. All the groups, except group (D), were experimentally infected whit mixed Eimeria spp. (E. Tenella, E. maxima, E. necatrix and E. brunetti) on day 14. Group (A), was treated whit an herbal mixture. Group (B), was treated whit Toltrazuril. Group (C), was experimentally infected with mixed Eimeria spp. But they didn’t have any treatment, this group was our positive control, as expected, this group had the poorest results and more mortality than other groups. Group (D), wasn't infected and was healthy all the experiment period, this was our negative control. Performance indices, fecal oocyst excretion, and intestinal lesion score were determined during the experiment. Treatment with an herbal complex significantly reduced the negative performance and pathogenic effects associated with Eimeria spp. at a level that was comparable with toltrazuril. In summary, the anticoccidial activity of the mentioned herbal complex recommends its use as an alternative anticoccidial agent to chemotherapeutic drugs for controlling coccidiosis. |
