*CON; energy-protein supplement without any feed additive (n = 14) - Probiotic; energy-protein supplement containing 2 g of probiotic/animal per day (n = 14). The probiotic was composed of Bacillus licheniformis and Bacillus subtilis (6.4 × 10⁹ CFU/g). 1Standard error of mean;2 P-value; The significance level was set at P ≤ 0.05, and 0.05 < P ≤ 0.10 was considered a tendency
