Abstract: Coccidiosis is one of the major parasitic diseases of poultry. In this study, to compare the effects of coccidiostatic drugs on fecal oocyst shedding and body weight gain of coccidi-infected broiler chickens, 180 one day old Ross 308 broiler chicks were randomly assigned to four treatments. Each treatment contained 3 replicates of 15 chickens. Treatments 1 and 2 were fed diets supplem...
