Mean values (n = 3) in the same column with different superscripts differ significantly (). ^aTreatment groups having graded levels of protein, i.e., TCP20, 200 g/kg protein; TCP25, 250 g/kg protein; TCP30, 300 g/kg protein; TCP35, 350 g/kg protein; TCP40, 400 g/kg protein; TCP45, 450 g/kg protein. ^bSOD, superoxide dismutase activity is expressed as 50% inhibition of epinephrine auto-oxidation/mg protein/min. ^cCAT, catalase activity is expressed as nanomoles of H₂O₂ decomposed/min/mg protein.
