The basal diet served as a control (C), and different levels of herbal feed additives were supplemented to the basal diet as follows: 0.5% bilberry leaves (E1) and 1% walnut leaves (E2). All data are reported as mean values ± standard deviation (SD) and statistical significance, where ns: p > 0.05; * p ≤ 0.05; ** p ≤ 0.01; *** p ≤ 0.001; (n = 10); n: number of replicates.
