^a-cMeans in a column not sharing a common superscript were different (P < 0.05).

Abbreviations: Cha, Challenged with cocci; Noncha, Nonchallenged.

¹SEM = Standard error of mean, 0 = Normal, 1 = slight, 2 = moderate, 3 = severe lesion score.

²Means of nonsignificant interactions are not listed.

³Fisher's LSD test was not able to separate means of challenge effects on jejunum and ileum coccidial moderate lesions (score 2) so only P-values were listed in the table with superscripts.
