The significance (p-values) of the correlation between a cows’ physiological indexes and bacterial communities were assessed by permutating 2000 times using the method in the R VEGAN package. The goodness of fit statistic of RDA, the squared correlation coefficient (r²), which measures the correlation between cows’ physiological indexes and bacterial communities, is showed in this table. The abbreviations are the same as those shown in the footnote to Table 2.
