Values are mean of triplicates (n=3) and presented as mean ± SD.
The determined dietary PA levels were 16, 107, 226, 317 and 424 mg kg^–1 for P0, P100, P200, P300 and P400, respectively.

Different superscripts in each column indicate significant differences (p < 0.05).
PA, pantothenic acid; B cell, blasenzellen cell; F cell, fibrillar cell; R cell, resoprtive cell; ANOVA, analysis of variance.
