This experiment was conducted to investigate the histopathologic changes of heart, lung, liver and kidney of broilers under chronic heat stress. Fif teen birds (n = 15), twenty-one days old were kept at controlled temperature chamber ranged between 34 and 35°C for 20 days. At 41 days of age the birds were sacrificed for data collection. Under microscopic examination of heart, massive myofibrillar degeneration with hemorrhage, general fatty degeneration of myofibers and diffused myocarditis containing organisms were found in 10 out of 15 broilers (67%). The major histopathologic changes of lung were related to v.ein and arteriole massive congestion with interalveoli septum hemorrhage and edema. These changes were observed in 13 out of 15 broilers (87%). Almost all liver showed fatty degeneration with narrowed sinusoid. Congestion of liver central vein were found around 50% of samples, beside necrosis with heterophils and lymphocytes that was observed in some parts of the liver, especially in the portal region in 8 out of 15 broiler (53%). In the kidney, the most histopathologic changes was hidropic degeneration (70%), which largely found in renal tubular epithelia cells, beside hemorrhage and accumulation of heterophils in many inflammatory areas. • Keyword :Chronic Heat stress ;Broiler ;Histopathology of Heart, Lung, Liver and Kidney
