Immunotherapeutic effects of some sugar cane (Saccharum officinarum L.) extracts against coccidiosis in industrial broiler chickens

► Oral administration of aqueous and ethanolic extracts of sugar cane enhances the natural immunity in chickens. ► After artificial infection with Eimeria spp. (local isolates; E. tenella, E. acervulina, E. necatrix), less severe outcomes in chickens administered with sugar cane extracts. ► Elicited humoral response against Eimeria spp. ► Decreased oocysts per gram of droppings and higher weight gain in chickens. ► Decreased mortality and lesion scoring.
