Each value is the mean value of 4 replicates.
PC, basal diet in animal welfare density; NC, basal diet in high stocking density; PT1, basal diet with PFA1 in high stocking density; PT2, basal diet with PFA2 in high stocking density; PT3, basal diet with PFA3 in high stocking density; PT4, basal diet with PFA4 in high stocking density; PT5, basal diet with PFA5 in high stocking density.
Means within column with different superscripts differ significantly (p < 0.05).
WBC, white blood cell; TNF-α, tumor necrosis factor-α; IL-6, Interleukin-6; PFA, phytogenic feed additives.
