Note: A indicates IFA positive piglets in total piglets in each group. B indicates average score of IFA signal in each group. IFA signal was scored for duodenum, jejunum, and ileum sections at ×10 magnification based on the following criteria: score 0 = no IFA signal was observed in villi; score 1 = a small amount of IFA signal was observed in villi; score 2 = a moderate level of IFA signal was observed in villi; and score 3 = a large amount of IFA signal was observed in villi. Average score for each group is shown.
