Evaluation of the efficacy of maduramacin ammonium in combination with roxarsone and avoparcin in caged broiler chickens.
1. The anticoccidial activity of maduramicin ammonium (5 mg/kg food) administered alone or with roxarsone (50 mg/kg food) and/or avoparcin (10 mg/kg food) was evaluated in battery-reared broilers artificially challenged with recent field culture mixtures containing Eimeria acervulina, E. maxima and E. tenella or E. mivati, E. necatrix and E. brunetti. 2. Maduramicin ammonium exhibited a high degree of anticoccidial activity and the addition of roxarsone and/or avoparcin in food at recommended concentrations did not adversely affect the activity.
