Abstract
Decoquinate administered orally in a grain mix at dosages of 0.5, 0.538, 0.7 and 0.8 mg/kg of body weight suppressed oocyst discharge and bloody diarrhea in calves inoculated 3 days later with 100,000 oocysts of Eimeria bovis or with 100,000 oocysts each of E. bovis and E. zuernii. Doses of 0.1, 0.163, 0.243, 0.3 and 0.362 mg/kg of body weight gave only partial suppression of oocyst discharge and diarrhea. Clinical signs of coccidiosis did not recur for 23 days after the treatment was discontinued.
