  1. 1Diets fed to turkeys containing DL-methionine (DLML and DLMH) and the equivalent amount of DL-methionine hydroxyl analogue (MHAL and MHAH) at two levels: low (L) and high - (H)
  2. 2Low level - 0.55 and 0.45% and high level - 0.78, 0.65%, in weeks 1–4 and 5–8 of feeding
  3. 3Sources of methionine: DL-isomer (DLM) and DL- methionine hydroxy analogue (MHA)
  4. 4SEM, standard error of the mean
  5. 5Vit C: vitamin C, SOD: superoxide dismutase, CAT: catalase, LOOH: lipid peroxides, MDA: malondialdehyde
  6. a-bvalues differ significantly
