Mean values for each feature (± SEM) are presented. These measurements were compared with those of TDJuv and Juv birds, which are presented in Table 1. Features that showed statistically significant differences between groups are presented separately, along with the p-values and degrees of freedom (DF) for the Bonferroni-corrected pairwise comparisons.
