Medication of feedlot calves infected with Eimeria spp. by a combination of sulfamonomethoxine and ormetoprim.
Feedlot calves naturally infected with Eimeria spp. were medicated by a combination of sulfamonomethoxine and ormetoprim (Ektecin). Calves, less than one year old and positive for coccidiosis, were administered with Ektecin (5, 10 and 20 ml/100 kg of body weight/day) and Daimeton (100% sulfamonomethoxine: 5 g/100 kg of body weight/day) for five days. No diarrhea were found on and after 3 days of medication in all the groups, and no oocysts were detected on and after day 5, 2, 1 or 3 from calves of the respective medicated groups. In samples from a group of calves administered with lowest dose of Ektecin, eimerian oocysts of 4 species were detected on day 0, and additionally 3 species (totally 7 species) were found on day 3 of medication.
