BACKGROUND: Coccidiosis is recognized as the parasitic disease that has the greatest economic impact on poultry production. Modern poultry production is largely dependent upon anticoccidials.
OBJECTIVES: The aim of the present study was to determine and compare the efficacy of two chemical anticoccidials [Clopidol and Diclazuril] on oocyst shedding and their probable effects on growth performance and feed efficiency of broilers in experimental coccidiosis.
METHODS: One hundred and twenty Ross 308 one day old broilers were randomly assigned into 4 groups: CON+, infected with Eimeria mixed oocysts but not medicated; CON-, not infected and not medicated; CLO, infected and medicated with Clopidol; DIC, infected and medicated with Diclazuril. Chickens in all groups except negative control were inoculated by mixed sporulated oocysts of pathogenic Eimeria at the end of the 3rd week of age. Oocyst shedding was counted using a Mc Master counting chamber. Body weights, body weight gains, and feed conversion ratio were determined on weekly basis. CONCLUSIONS: It is reported that some anticoccidials reduce feed consumption and feed conversion. It seems that neither of the present synthetic anticoccidials is completely satisfactory in controlling coccidiosis economic losses and new strategies are urgently required.
