- A study of the potential of using aqueous extracts of pawpaw (Carica papaya) roots, leaves and seeds as anticoccidia agents in chicken. By:-Anthony Annan-Prah
Abstract
This study sought to validate the use of pawpaw (Carica papaya) in some rural communities in Ghana to control of coccidiosis in chicken. To 5-week old Lohman Brown broiler chicken that had been artificially infected with sporulated oocysts of coccidia, various concentrations of aqueous extracts of pawpaw seeds, roots, were orally administered over an 8-day period. A commercial coccidiostat, Atlacox , and potable drinking water were also given for comparison and as control. Using the McMaster method, the faeces were assayed for coccidia oocyst production over the 8-day period. Results suggested that all the various concentrations of aqueous extracts of pawpaw parts reduced coccidia populations. Aqueous extract of pawpaw seeds (6.25%), pawpaw leaves (6.25%), roots (12.5%) and control commercial coccidiostat, Atlacox, reduced counts by 4.2 log10 ,1.46 log10, 1.6 log 10 and 1.4 log 10 respectively within a 4-day period. The aqueous extract of pawpaw seeds was, therefore, found to be most efficacious. Post-mortem inspection of the carcass of the slaughtered chicken did not show any visible lesions that warranted the meat being declared as unwholesome for consumption. The use of pawpaw parts, especially seeds, in some rural communities in the control of coccidiosis is suggested to be justified.
