The concentrations of soluble sulfide (S2−) and VFAs in the cecal content. a The concentration of soluble sulfide (S2−). b The concentration of VFAs. Error bars show one standard deviation, and the mean value was calculated from 30 replicates. The mean value is labeled above the error bars with different superscripts indicating a significant difference (P < 0.05). Hn: Hy-Line, Ln: Lohmann
