  1. PFT and PSP are the significant levels (GLM) for the effects of feeding time and species, respectively.
  2. *General linear model (GLM) analysis of variance with feeding time and species as fixed factors; where significant differences were detected (P < 0.05), a Tukey’s pairwise comparison or a t-test were applied.
  3. a–bDifferent superscript lowercase letters within each species and each parameter indicate significant differences (P < 0.05) throughout feeding time.
  4. A-BDifferent superscript uppercase letters within each feeding time and each parameter indicate significant differences (P < 0.05) between the species at the same feeding time.
