Fig. 2From: Effects of tannic acid on the immunity and intestinal health of broiler chickens with necrotic enteritis infectionRepresentative picture of the coccidia oocysts in the feces at d 28. No coccidia oocysts were found in the feces of the NC group. The number of coccidia oocysts gradually decreased with an increase of tannic acid additive levels. NC: no tannic acid treatment or NE infection; PC: NE infection + 0 mg/kg tannic acid; PTA1: NE infection + 250 mg/kg tannic acid; PTA2: NE infection + 500 mg/kg tannic acid; PTA3: NE infection + 750 mg/kg tannic acid; PTA4: NE infection + 1,000 mg/kg tannic acid.
