Abstract

The present study was undertaken to examine the toxic effects of mercury on gross and histopathological changes in visceral organs of broiler chickens. Twenty four birds of either sex were evenly divided into two groups of twelve birds each. Group I birds were kept on standard feed and water and served as control, whereas Group II birds were given mercuric chloride @ 50 ppm/bird/day mixed with standard feed. After 45 days, all the birds were sacrificed and visceral organs collected for gross and histopathological examination. Group II birds fed with mercuric chloride revealed marked enlargement and haemorrhage in liver with dilatation of sinusoids, focal areas of fatty degeneration and necrosis of hepatocytes. Kidney showed swollen glomerular tuft and detachment of tubular epithelium. Cardiac lesions included severe haemorrhage, hydropericardium and necrosis. Lungs showed reddish brown discoloration, infilteration of mononuclear cells and thickening of alveolar septa. Histopathological section of the brain revealed congestion, vacuolar degeneration, perivascular cuffing and gliosis. In view of toxic effects induced by mercury, it is essential to periodically monitor the level of this heavy metal in poultry feed and water.
