title: Chemo-prophylaxis of turkey coccidiosis: Activity of clopidol with methylbenzoquate and amprolium with ethopabate against a mixed infection of Eimeria meleagrimitis and Eimeria adenoeides.
abstract: A comparison has been made between the use of clopidol-methyl benzoquate and amprolium-ethopabate mixtures for the prophylactic control of Eimeria adenoeides and Eimeria meleagrimitis in turkeys. Twenty four poults were randomly allocated to each of the following treatments: non contaminated non treated; contaminated non treated; contaminated treated with 100 ppm + 8.35 ppm clopidol methyl benzoquate; contaminated treated with 200 ppm + 16.70 ppm clopidol methyl benzoquate; contaminated treated with 125 ppm + 8 ppm amprolium ethopabate. The amprolium-ethopabate mixture only partially controlled an infection with 50,000 sporulated oocysts of E. adenoeides and 200,000 oocysts of E. meleagrimitis. The clopidol-methyl benzoquate mixture completely controlled such an infection at the higher concentration (200 ppm + 16.70 ppm) and almost completely controlled it at the lower concentration (100 ppm+ 8.35 ppm). Drug withdrawal studies showed that the clopidol-methyl benzoquate mixture is coccidiostatic for the two species studied.
