Alpha diversity of gut microbiota at genus level affected by Salmonella Typhimurium infection, intramuscular injection and feed withdrawal. a Alpha diversity of gut microbiota before the intramuscular injection (week 7 Salmonella Typhimurium post-infection). b Alpha diversity of gut microbiota after the induction of intramuscular injection (week 8 Salmonella Typhimurium post-infection). c Alpha diversity of gut microbiota before the feed withdrawal (week 7 Salmonella Typhimurium post-infection). d Alpha diversity of gut microbiota after the feed withdrawal (week 8 Salmonella Typhimurium post-infection). Alpha diversity was measured by Shannon index in Calypso software. For treatment group details, refer to Table 1
