Abstract: Measures of ileal digestibility (ID) are used routinely as estimates of amino acid (AA) bio-availability in pig feed ingredients. Values for ID may be expressed as apparent (AID), standardized (SID), or true (TID). Values for AID are calculated by deducting the total ileal outflow of AA (the sum of endogenous losses (IAA end ) and non-digested dietary AA) from dietary AA intake. The IAA end may be separated into basal losses, which are not influenced by feed ingredient composition, and specific losses induced…
