•Oxidative stress was induced by fenvalerate and sodium nitrate exposure in buffalo calves.•Fenvalerate produced significant elevation in LPO and GPx, while decline in GSH, SOD and CAT.•Sodium nitrate produced significant elevation in LPO and NOx, while decline in GSH, SOD and CAT.•Combined exposure to fenvalerate and sodium nitrate produced appreciably more prominent elevation in LPO and decline in GSH.
The toxic effects of pesticides and minerals have been explored in different species, but still there is paucity of information regarding their combined toxicological effects. The present investigation reports oxidative stress induced by oral subacute exposure to fenvalerate (1 mg/kg) and sodium nitrate (20 mg/kg) alone, as well as in combination daily for 21 days in buffalo calves. Fenvalerate exposure produced significant elevation in lipid peroxidation (LPO), glutathione peroxidase (GPx), while it produced significant decline in blood glutathione (GSH) levels, superoxide dismutase (SOD) and catalase (CAT). No significant alteration was evidenced in nitric oxide (NOx) levels. Oral exposure to sodium nitrate produced significant inclination in LPO and NOx, while on the other hand significant depreciation in SOD and CAT with no significant change in GPx activity. Combined exposure to fenvalerate and sodium nitrate produced severe effects with an appreciably more prominent elevation in extent of LPO and decline in blood GSH levels.
