  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 was applied.
  3. a–dDifferent superscript letters within the same sensory attribute indicate significant differences (P < 0.05) between the samples.
  4. A 1-9 scale and descriptive analyses with 12 semi-trained assessors were used.
