Heatmap of spearman’s correlation between intestinal microbiota and intestinal morphology. a, b and c were correlation results base on the relative abundances of 25 key phylotypes at genus level on d 3, 14 and 42 respectively. The colors range from blue (negative correlations) to red (positive correlations). Significant correlations are noted by 0.01 < P ≤ 0.05 *, 0.001 < P ≤ 0.01**, P ≤ 0.001***
