  1. a,b,cMeans in the same column followed by different letters differ significantly by the Tukey test, P < 0.05. Results are presented as mean ± standard error, SE. Each bird was considered an experimental unit, n = 6
  2. dExpressed as nmol of carbonyl groups/mg of protein
  3. eTAC = total antioxidant capacity, expressed as percentage, %
  4. fCatalase activity, expressed as the amount of hydrogen peroxide, H2O2 consumed per minute per milligram of protein
  5. gSOD = superoxide dismutase activity, expressed as SOD unit/mg of protein
  6. hUC = unchallenged broilers
  7. iEC = Eimeria-challenged broilers
  8. jNS = non-supplemented diet
  9. kdl-Met = diet supplemented with free methionine (dl-methionine 99%)
  10. ldl-MMet = diet supplemented with methionine dipeptide (dl-methionyl-dl-methionine 95%)
