Abstract

The present study evaluated the effects of exposure to different doses of sodium chlorate in 10-week-old pigs. Twenty pigs were divided into four equal groups and treated with different doses of sodium chlorate: 0, 125, 250 and 500 mg kg−1 body weight per day via the drinking water for 7 consecutive days. The results showed a significant decrease (P < 0.05) in red blood cell and white blood cell counts, packed cell volume, haemoglobin, blood urea nitrogen (P < 0.001) and creatinine levels, and an increase in aspartate aminotransferase and alanine aminotransferase (P < 0.05) activities in swine administered sodium chlorate at a dose of 500 mg kg−1body weight per day. The histopathological study revealed increased numbers of vacuoles in the convoluted tubules, tubular necrosis and degeneration of the renal tubular epithelial cells, depletion of nuclei and lobular necrosis of the liver in all pigs treated with sodium chlorate at 500 mg kg−1 body weight per day. Thus, 7-day administration of sodium chlorate at 500 mg kg−1 body weight per day to pigs affects the liver and kidney tissues as well as the haematologic and serum biochemical parameters.
