Fig. 4

Effect of different sources of grains on functional prediction of bacteria in the stomach content of the weaned foals. “A” shows the histogram depicting the relative abundance of the first 35 functional bacteria predicted in the stomach content of the foals fed with three different diets. The vertical coordinates of the figure indicate the relative abundance of the predicted functions and the horizontal coordinates indicate the grouping, with c indicating the corn group, o indicating the oats group, and b indicating the barley group. The names of the functions indicated by letters in the figure are shown in the legend on the right. “B” compares the first 35 functional bacteria that were significantly different between the oats and barley groups by using t-test. The groupings indicated by the letters in the figure are shown in the legend at the top left. Orange and o indicate the oats group and blue and b indicate the barley group. “C” shows that the corn and oats groups were significantly different in the top 35 functional bacteria predicted using t-test. The groupings indicated by the letters in the figure are shown in the legend at the top left. Orange and c indicate the corn group and blue and o indicate the oats group
