G1= Rabbit bucks supplemented with 1 mL inorganic commercial Se (100 mg/L) per liter drinking water, G2= Rabbit bucks supplemented with 0.5 mL synthesized NS (100 mg/L) per liter drinking water, G3= Rabbit bucks supplemented with 1.0 mL synthesized NS (100 mg/L) per liter drinking water, G4= control un-supplemented rabbit bucks.
