Sulfadimethoxine in Prevention of Turkey Coccidiosis

Abstract

SULFADIMETHOXINE, N′-(2,6-dimethoxy-4-pyrimidinyl) sulfanilamide, since first synthesized by Bretschneider and Kloetzer (1955), and its antibacterial activity reported by Schnitzer et al. (1958), has stimulated a great deal of interest among the workers engaged in the field of experimental chemotherapy. In fowl, Mitrovic and Bauernfeind (1967) reported that sulfadimethoxine was therapeutically highly effective against all pathogenic species of Eimeria in chickens and turkeys. Mitrovic (1967) reported that sulfadimethoxine was also effective in therapy of fowl cholera in chickens and turkeys and infectious coryza in chickens. Since the chemoprophylactic efficacy of sulfadimethoxine in turkey coccidiosis has not as yet been investigated, the studies undertaken and completed are the object of this report. MATERIALS AND METHODS The chemoprophylactic efficacy studies were carried out in battery and floor pen trials. Battery trials and experimental design. Day old Broad Breasted White (BBW) turkey poults, obtained from a commercial hatchery, were kept in wire floored, . . .
