Experimentally, ochratoxicosis and coccidiosis were induced singly and in combination in 6 groups of broilers each consisting of 25 chicks. Ochratoxicosis was induced by feeding with dietary ochratoxin A (OA) at a concentration of 0.5 and 1 ppm tor 23 days. Coccidiosis was induced by inoculating 50,000 sporulated oocysts of E. tenella as 14th day.

Pathological changes observed as early as week 2 in 30 ppm level clarified the toxic effects of endosulfan in broiler chicken at a lower dose itself. Lymphoid depletion observed in the spleen and bursa indicated the immunosuppressive effect by endosulfan. Further studies to elucidate the mechanisms of toxicity of endosulfan in broiler chicken are needed.
