  1. Values are mean ± SEM (standard error of the mean).
  2. †, ‡, § Means within a row with different superscripts differ (P < 0.05).
  3. Effect of species: Means within a row are different between species (P < 0.001) for chymotrypsin and Elastase II.
  4. IU1: International Unit.
  5. %Δ: Difference between values: Adult values-Young values (Δ1) or Ruminant values- Milk-fed values (Δ2) expressed as % of “Young values” and “Milk-fed values” respectively.
