Abstract
- Abstract Background The Chinese pig breed Bamei faces numerous challenges, such as antibiotic abuse, feed shortages, weaning stress, low immunity and disease resistance after weaning. Probiotic-fermented feed is an ideal profile that can improve the intestinal microbiota, promote the digestion and absorption of nutrients, and improve immunity. However, the combined effect of long-term intake of probiotic-fermented feeds on the intestinal microbiota, intestinal metabolic profiles, and immunity in pigs is not well understood. Here, we investigated the effects of feeding basal feed, Lactiplantibacillus-fermented feed, Bacillus subtilis-fermented feed, mixed-fermented feed, and antibiotic-added feed for 100 days on the gut microbiota, immunity, and metabolism of Bamei pigs after feeding five different fermented feeds by using 16S rDNA high-throughput sequencing, enzyme-linked immunoassay, and untargeted metabolomics, respectively. Results 16S rDNA sequencing revealed that after the piglets were fed five different feeds for 50 days, the structure of the intestinal microbiota of the Bamei pigs was significantly altered, and feeding the mixed Lactiplantibacillus (L.) plantarum and Bacillus (B.) subtilis-fermented feed not only increased the α-diversity of the intestinal microbiota and the relative abundance of Lactobacillus, but also suppressed the growth of the conditional pathogens, Clostridium and Streptococcus. The Sobs and Shannon indices were significantly lower (p
