Abstract

Toltrazuril, a triazinone anticoccidial drug, was evaluated for efficacy at 8 ppm against Maduramicin 5 ppm in feed under a commercial trial condition with natural coccidial exposure. The experiment was carried out in 6 trials. Trial 1 was a preliminary study with 1,000 chickens testing for Toltrazuril while 4,000 chicks were used to evaluate Toltrazuril and 3,400 for Maduramicin in trial 2 to 6. Necropsy and score lesion reading were performed. Subclinical coccidiosis of Eimeria acervulina and E. maxima exhibited in Toltrazuril treated group, and E. acervulian, E. maxima and E. tenella in Maduramicin group. Lesion scores were not substantially different. Infection in rainy season appeared to be higher than others. Oocyst per gram of feces was only slightly higher in Maduramicin group than Toltrazuril. The oocysts production reached peak in the 5th week.
