an increasing trendP = 0.068
At the genus level, there was an increasing trend in the relative abundances of Blautia ( P = 0.068) and Dorea ( P = 0.041) in the SA and SP groups at 65 days of age, however, unclassified_Clostridiales ( P = 0.037) and SMB53 ( P = 0.041) were decreased ( Figure 2I ) compared with the control and SS groups.
