  1. The score is based on a combination of intestinal hyperplasia, inflammation and L. intracellularis antigen and distribution of the pigs in each group into normal (score 0), mild (score 1, 2 or 3), moderate (score 4, 5 or 6) or severe (score 7, 8 or 9).
  2. aDifferent superscripts (A,B) indicate a significant different weight gain (P < 0.05) among groups during a time period.
