Comparative study between chemical anticoccidial medication and natural prepared products on experimentally infected broiler chickens

This study was conducted in order to compare well established used chemical anticoccidial medication (diclazuril) against natural prepared safe alternative products of garlic extract (GE),Moringa oleifera (MO) leaves extract, onion extract (OE), in order to control experimentally infected withEimeria tenella species in chickens. Performance parameter in form of average body weight (ABW) and feed conversion rate (FCR) were studied together with biochemical parameters (malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT), mortality rate, oocyst count in addition to total white blood cell (WBCs), lymphocytes and heterophils counts. Histopathological examination of intestinal tract in all test groups was studied. Results revealed that the lowest mortality rate was found in group treated with MO leaves extract. All challenged herbal extract treated groups revealed ABW and FCR lower than diclazuril treated infected group. All treated groups were lower in both average lesion score and average oocyst count two weeks post challenge when compared with control positive group indicate positive impact of all studied therapies either chemical or herbal products but with variable degrees as best effect was diclazuril followed by MO group, followed by GE group and finally group treated with OE. Experimental infection of chickens withE. tenella oocysts significantly increased MDA concentration when compared with control negative non-treated group (P <  0.01). However, i...
