Difference in serum immune parameters between HADG and LADG goats (6-month-old, n = 10 each group), and the relationship between these immune parameters and ADG-related rectum microbiota. A albumin (ALB), (B) globulin (GLB), (C) IgG, (D) the ALB to GLB ratio (ARG), significant differences were tested by t-test. The bars represent SEM. E Correlations between serum immune parameters and ADG-related microbiota, rectum SCFA of HADG and LADG (Spearman’s correlation). The color gradient represents the values of correlation coefficients. ^#P < 0.1, ^*P < 0.05, ^**P < 0.01
