The efficacy of toltrazuril and amprolium was evaluated in experimentally induced caecal coccidiosis in broiler chicken.It was found that toltrazuril prevented the establishment of caecal coccidiosis by degeneration and disintegration of first generation of schizonts. However, in the amprolium treated birds, few intact first and second generation schizonts and also micro and macrogametocytes were noticed on microscopic examination. Occasionally oocysts were also found. It was concluded that toltrazuril has a coccidiocidal effect whereas amprolium is coccidiostatic in nature based on histopathological studies.
