Fecal Microbial Species Diversity Analysis of Weaned Piglets In α diversity, the observed species in the feces of piglets in the CON group significantly increased compared to the 0.2% group ( p < 0.05, Table 2 ); and the chao1 index in the CON group showed an increasing trend compared with the 0.2% group ( p < 0.05, Table 2 ), while other diversity index showed no significant difference ( p > 0.05, Table 2 ). β diversity results showed that the microbial community composition of the 0.2% group was significantly different from that of the CON group and the 0.125% group ( p < 0.05, Figure 1 C,F). 3.3.
