Abstract

A total of 33 chickens was used; each chick was inoculated with approximately 12,000 to 15,000 sporulated Eimeria tenella oocysts. Chickens were used in nine groups, four treated with thiotepa, and four treated with 2.5 dichloro-2, 4 dinitro benzene sulfonanilide, while the remaining group served as a control. Groups, two, four, six and eight were given doses of thiotepa at levels of 1.54 mg/bird, 3.08 mg/bird, 6.16 mg/bird and 9.24 while groups three, five, seven and nine were given doses of 2, 5 dichloro-2, 4 dinitro- benzene sulfonanilide at levels of 1.54 mg/bird, 3.08 mg/bird, 6.16 mg/bird and 9.24 mg/bird. Both groups treated with both drugs showed a significant decreases in oocyst production with increase of drug concentration.
