  1. 1 Feeds administered to uninfected (0) and infected (HE) turkeys in weeks 1–4 and 5–8, contained DLM and the equivalent amount of MHA at two levels: low (L) - 0.55, 0.45, and high (H) - 0.78, 0.65, respectively [% as fed]
  2. 2SEM- standard error of the mean
  3. 3nd – not detected: no significant infection x dose, infection x source, dose x source or infection x dose x source interactions
