Evaluation of pomegranate (Punica granatum) pericarp aqueous extract on Eimeria spp. from Japanese quails (Coturnix japonica)

Antibacterial, anti-inflammatory and antiparasitic properties have been associated with the extract of pomegranate (Punica granatum) in several animals and conditions. The Japanese quail (Coturnix japonica), originated from North Africa, Europe and Asia, is used worldwide as an experimental animal and model for aviculture. The current study investigated the effects of the pomegranate pericarp aqueous extract on the shedding, viability and morphometry of three Eimeria spp. from Japanese quails, besides the weight gain and genotoxic activity. Although the pomegranate is recognized by multiple properties, including anti-coccidial, in the current study the results are contrary. The treated group shed greater amount of oocysts; the sporulation times and viability were similar in both groups; despite some morphometric differences, these were not expressive; weight gains were similar; and the pomegranate had insignificant effect genotoxic. Finally, these results suggest that the pomegranate pericarp extract did not influence on Eimeira spp. from Japanese quails; therefore, the pomegranate pericarp extract is not suggested in the prevention/treatment of coccidiosis in Japanese quails, or at least not using methods of preparation and administration applied in this study.
