Efficacy of arprinocid against coccidiosis of broilers in battery and floor-pen trials.

Abstract
Medication of broilers with arprinocid [9-(2-chloro-6-fluorophenylmethyl)-9H-purine-6-amine] gave protection against the effects of coccidiosis in both battery and floor-pen trials. In battery trials, efficacy was tested on single-species inoculations of Eimeria acervulina, E. mivati, E. necatrix, E. maxima, E. Brunetti, and E. tenella. Two strains of each species recently recovered from the field, were tested separately. In floor-pen trials, all six species, both field and laboratory strains, were used as a mixed infection. In batteries, 60 and 70 ppm essentially eliminated coccidiosis-induced mortality and weight depression. Effects of 50 ppm on weight gain were variable. The effectiveness of different medication levels varied between strains within a species. In floor-pen trials, 40, 60, or 80 ppm was effective in controlling mortality and weight depression, and increasing feel-conversion ratios. All levels were significantly as effective as monensin in protecting against coccidiosis. With severe exposure to coccidia, 60 and 80 ppm gave significantly lower lesion socres than did 40 ppm of arprinocid or 120 ppm monensin.
