A study was conducted on twenty indigenous goat kids allocated into two different groups. All animals were offered ad libitum rice straw and berseem hay (40:60).

There was significant decrease in serum sodium (60.68 mEq/L), increase in serum potassium (34.50 mEq/L) and increased activity of AST (340.42 U/L) and ALT (164.96 U/L) was observed in kids of group T₂ in comparison to the controls (T₁). On histopathological examination mild degenerative changes in kidney of group T₂ with congestion in intertubular vessel, granular cytoplasm of the epithelial cells in PCT and DCT, necrosis and swelling of the epithelial cells, congestion of vessels and cloudy swelling was observed in PCT and DCT.
