Ameliorative Effect of Pomegranate Peel Powder on the Growth Indices, Oocysts Shedding, and Intestinal Health of Broilers under an Experimentally Induced Coccidiosis Condition.

Coccidiosis stands as one of the most prevalent enteric parasitic diseases in broilers. While antibiotics have traditionally been used for the control of coccidiosis, concerns related to drug residues and the emergence of resistance in chickens have prompted consumer apprehensions. In this study, 600 Ross 308 broiler chicks were randomly divided into five groups: a control group without specific treatments (NC), broilers deliberately exposed to Eimeria tenella (positive control), broilers challenged with E. tenella but dosed with antibiotics (AT), and two groups experimentally exposed to E. tenella while simultaneously receiving pomegranate peel powder (PPE) at dosages of 3 g/kg (3PPP) and 6 g/kg (6PPP). The results revealed that all Eimeria -treated birds exhibited significantly worse growth performance compared to the NC. Notably, a marked improvement was observed in birds infected with E. tenella when supplemented with 6PPP. Both 3PPP and 6PPP supplementation significantly reduced lesion scores, mortality, and oocysts per gram (OPG). Furthermore, histological examination of the cecum indicated that the villus dimensions were restored by PPP supplementation in infected birds. In conclusion, Eimeria -infected birds supplemented with 6PPP experienced an enhanced growth rate, lowered lesion scores, alleviated oocyst shedding, and improved intestinal histological dimensions.
