Efficacy of commonly used coccidiostats against experimental E. tenella infection in broiler chickens

摘要

Efficacy of three commonly used coccidiostats viz. maduramicin, salinomycin and lasalocid sodium was evaluated in experimentally induced E. tenella infection in broiler chickens. The efficacy was assessed based on percent weight gain, feed conversionratio, oocyst index, mortality percent and lesion score by using global index formula. Salinomycin showed good efficacy (85.5%) in E. tenella infected birds whereas limited efficacy (77.7 and 74.1%) was observed with maduramicin and lasalocid sodium.
