Abstract

The present study was conducted to investigate the hazardous effects of lead on blood, liver and kidney of Lohi sheep. The adult Lohi sheep (n=48) were divided into treatment and control groups. The treatment group was administered lead acetate at a dose of 70 mg/kg live body weight daily for a period of 90 days orally. Six sheep from both groups were randomly selected and necropsied at day 0, 30, 60 and 90. The serum and tissue samples were collected and analyzed for Pb concentration by atomic absorption spectrophotometry. The lead has significantly decreased the values of RBC, Hb and PCV; whereas ALT, AST, ALP, urea and creatinine levels were found higher in the treatment group. It is concluded that the tissue damage in Lohi sheep was dependent on the accumulation of Pb residues in liver and kidney. This indicates that the lead intoxication could be harmful to sheep and ultimately poses threat to public health. This is a first long-term experimental study which correlates the effects of chronic Pb toxicity on blood and edible tissues of Lohi sheep.
