  1. aCP(FJ6) (C8-1): Clostridium perfringens type G strain (FJ6)(C8-1)
  2. bE.n(G): Eimeria necatrix Guangdong strain
  3. cCTL: control group
  4. dDietary factor: maize-based diet containing 60% fishmeal (1:1)
  5. eNE case is defined by lesion score reaching 2 or above
  6. f01 chicks died as early mortality in the group CTL and Eimeria, dissimilar letters indicate a significant difference compared with CTL group at 95% confidence level (independent t-test)
  7. *Means highly significant (P < 0.01)
