  1. a,b,c,d Means within the same column with different superscripts differ significantly (P < 0.05)
  2. eNE = Co-challenged with Eimeria spp. and Clostridium perfringens; −, without NE challenge; +, with NE challenge
  3. fsIgA = secretory immunoglobulin A
  4. gAll values represent the means with subtracted background OD490nm. Sera were diluted at 1:50 for the C.perfringens antigen detection, respectively, using ELISAs. Each sample was assayed in duplicate
  5. hIAP = intestinal alkline phosphatase, μmol/mg protein
  6. iSEM, standard error of the mean
  7. jP-values represent the main effect of the diet, the main effect of NE challenge, and the interaction between the dietary treatments and NE challenge
