^†CDFM (United Animal Health, Sheridan, IN), all values are overall least square means of days 21 and 42 combined data, total AA were not reported in the distal colon due to insufficient sample size, n = 12 to 16 representative pigs per treatment, and n = 8 to 11 for Trp due to insufficient sample collection.

^a,bValues in a common row lacking a common superscript differ (P ≤ 0.05).

^x,yValues in a common row lacking a common superscript tend to differ (P ≤ 0.10).
