摘要：The present experimental work was conducted to elucidate the pathological changes in broiler chickensafter ziram intoxication. For this study 120 apparently healthy broiler chicks were reared up to 2weeks of age and allocated randomly to two groups, i.e. sub-chronic toxicity (N=90) and control group(N=30). Toxicity was induced in broiler chicks by giving 1 mg/kg body weight per day for the studyperiod of 90 days in case of sub-chronic intoxication. At the end of the experimental period theinvestigations revealed depletion of lymphoid tissue from the lymphoid organs which were suggestiveof immunosuppressive and immunomodulatory effects of ziram in chicken.
