Comparison of gut microbes among calves with bloody diarrhea, watery diarrhea, and normal stools. a Relative abundance (%) at the phylum level. b Relative abundance (%) at the genus level. c PCoA of gut microbes based on the Bray–Curtis distance. d α-diversity (Chao1 and Shannon index) of gut microbes. Boxes of α-diversity denote the interquartile range (IQR) between the first and third quartiles (the 25th and 75th percentiles, respectively), and the line inside denotes the median. Whiskers denote the lowest and highest values within 1.5 times and the IQR from the first and third quartiles, respectively
