Rectum SCFA and their relationships with ADG-related microbiota. A Concentrations of SCFA in HADG and LADG goats (6-month-old, n = 10 each group). Significant differences were tested by t-test. The bars represent SEM. B Correlations between the rectum SCFA and growth rate of all young goats (n = 76, Spearman’s correlation). C Spearman’s rank correlations between ADG-related microbiota (relative abundance > 0.1%) and rectum SCFA (n = 76). The color gradient (in B and C) represents the values of correlation coefficients. ^#P < 0.1, ^*P < 0.05, ^**P < 0.01
