Abstract A floor-pen trial was conducted for assessing the efficacy of 0.3 and 0.4% concentration of two phytochemicals viz. IHP-250C and AV/CPP/12 against caecal coccidiosis caused by Eimeria tenella. Results of the trial indicated both the herbal anticoccidals were effective against clinical coccidiosis. IHP-250C 0.4% showed performance index (PI) 276 and average total oocyst production of 1.26 (million/bird). Weight gain record of uninfected-medicated group suggested that the drugs may have acted as growth promoters improving carcass characteristics. Histopathological finding revealed that drugs arrested the gametocytic stages of coccidia. This might be the cause of reduced oocyst output. The trial concluded that at higher (0.4%) concentration, both the drugs can be successfully used as a prophylactic in field conditions against caecal coccidiosis in broilers.
