a
The experiment was repeated in two replicate trials, and the data were combined. Data are presented as means ± standard deviations, n = 24. Values in a column followed by different capital letters differ significantly (P < 0.05).
b
Total VFAs include acetic, propionic, butyric, isobutyric, valeric, and isovaleric acids.
