  1. a, b, c, d Means within the same column with different superscripts differ significantly (P < 0.05)
  2. eEach value represents the mean of 6 birds per treatment (1 bird per replicate). Scores were given from 0 to 4 depending on the severity
  3. fNE = Co-challenged with Eimeria spp. and Clostridium perfringens; −, without NE challenge; +, with NE challenge
  4. gP-values represent the main effect of the diet, the main effect of NE challenge, and the interaction between the dietary treatments and NE challenge
  5. hSmall intestine values represent the average of duodenal, jejunal, and ileal scores
