title: Evaluation of the effect of anticoccidial drugs on size of parasite population and its development in litters.
abstract: Evaluation of the number of oocysts present in liters and of their rate of sporulation is relatively easy in floor pens. We have observed that contamination varies considerably according to the anticoccidial drug present in feed. Despite a difference in effect on parasitic development, some identical performances were noted in all groups treated. Among the anticoccidial drugs studied, Monensin is the one which least reduces contamination of environment; Halofuginone is the one which reduces contamination the most.
