The culinary-medicinal oyster mushroom Pleurotus ostreatus, procured from local sources, was processed for hot water and methanolic extraction. Extracts obtained were subjected to proximate analysis to determine the amount of crude protein, crude fiber, ash, ether, and nitrogen-free extracts. These extracts were evaluated for immunomodulating and antiprotozoal effects against coccidiosis in a broiler. Cellular immune investigation revealed significantly higher (P < 0.05) lymphoproliferative response to phytohemagglutinin-P in groups administered P. ostreatus extracts compared with controls. Humoral immune investigation revealed higher immunoglobulin (total Ig, IgG, and IgM) titers against sheep red blood cells in treated groups compared with controls. However, nonsignificant (P > 0.05) findings were observed in investigations of lymphoid organs. Antiprotozoal studies revealed a significantly higher (P < 0.05) percentage of protection against coccidiosis in groups administered P. ostreatus extracts when compared with controls. Moreover, lesion scoring and oocysts per gram of droppings observed in the control group were significantly higher (P < 0.05) compared with those in groups administered hot water and methanolic extracts of P. ostreatus. Results concluded that hot water and methanolic extracts of P. ostreatus had strong immune-enhancing activities. Further, these extracts also had excellent antiprotozoal activities against coccidiosis in a broiler.
