Effect of LZ on intestinal microorganisms in weaned piglets (n = 6). (A) Community abundance of P_Firmicutes, (B) community abundance of P_Bacteroidota, (C) community abundance of P_Campilobacterota, (D) community abundance of P_Actinobacteriota, (E) community abundance of P_Spirochaetota, (F) ratio of P_Firmicutes to P_Bacteroidota, (G) community abundance of g_Clostridium_sensu_stricto_1, (H) community abundance of g_Olsenella, (I) community abundance of g_Prevotella. CON = control group; LZ = lysozyme group. Values are means ± SEM. Statistical differences in mean values of all indices were evaluated by independent t-test. The asterisk (∗) means P < 0.05.
