ABSTRACT
Experiments were carried out in this work to study the effect of Robenidine and Spectinomycin, each alone and in combination on blood picture and histopathological findings of liver and kidneys. The hematological values of chickens, due to prolonged administration of Robenidine and Spectinomycin individually or in combination, showed a significant drop in red cell count, hemoglobin concentration, packed cell volume and lymphocytes. On the other h and, Robenidine causes increase in neutrophils and monocytes. The changes observed in chickens reared on Robenidine alone or in combination with Spectinomycin were confined to the liver and kidney and characterized by congestion, hemorrhages with mononuclear cell infiltration as well as degeneration and necrosis in focal areas. Meanwhile, the changes observed in chickens reared on Spectinomycin were confined only to the liver
