Continuous Feeding of Low Concentrations of Sulfaquinoxaline for the Control of Coccidiosis in Poultry

NUMEROUS sulfa drugs have been found valuable in the prevention and treatment of coccidiosis in poultry. Also various methods of using these drugs have been recommended. It is the belief of the authors that the inclusion of the medication in the feed continuously over a sufficient period of time to allow immunity to develop from natural exposure would be the safest and most economical method for controlling coccidiosis. This procedure would call for controlled infection rather than complete prevention of infection in order that the desired immunity might be established. Work at this station (Delaplane et al. 1947, and Grumbles et al. 1947) has shown that sulfaquinoxaline is effective against both cecal and intestinal coccidiosis. In these experiments 0.05 percent sulfaquinoxaline, fed in mash intermittently, and 0.033 and 0.0125 percent, fed continuously in mash, gave good results. These studies also have shown that sulfaquinoxaline used thus did not prevent the . . .
