Feed-additive probiotics accelerate yet antibiotics delay intestinal microbiota maturation in broiler chicken

Background: Reducing antibiotics overuse in animal agriculture is one key in combat against the spread of antibiotic resistance. Probiotics are a potential replacement of antibiotics in animal feed; however, it is not clear whether and how probiotics and antibiotics differ in impact on physiology and microbial ecology of host animals. Results: Host phenotype and fecal microbiota of broilers with either antibiotics or probiotics as feed additive were simultaneously sampled at four time points from birth to slaughter and then compared. Probiotic feeding resulted in a lower feed conversion ratio (FCR) and induced the highest level of immunity response, suggesting greater economic benefits in broiler farming. Probiotic use but not antibiotic use recapitulated the characteristics of age-dependent development of gut microbiota in the control group. The maturation of intestinal microbiota was greatly accelerated by probiotic feeding, yet significantly retarded and eventually delayed by antibiotic feeding. LP-8 stimulated the growth of many intestinal Lactobacillus spp. and led to an altered bacterial correlation network where Lactobacillus spp. are negatively correlated with 14 genera and positively linked with none, yet from the start antibiotic feeding featured a less-organized network where such inter-genera interactions were fewer and weaker. Consistently, microbiota-encoded functions as revealed by metagenome sequencing were highly distinct between the two groups. Thus, "intestinal microbiota maturation index" was proposed to quantitatively compare impact of feed additives on animal microecology. Conclusions: Our results reveal a tremendous potential of probiotics as antibiotics' substitute in poultry farming.

“…This also led to a significant classification of HN group with other groups in PCoA analysis. The HNST group had the highest abundance of genus Lactobacillus , which can improve the growth performance of broiler chicken and resist S. Typhimurium infections as probiotics ( Jahromi et al., 2016 ; Park et al., 2016 ).…”

“…The chyme provided nutrients for the growth of the microbiome in the gut, and the microbial metabolism can provide nutrients for the intestinal epithelial ( Fang et al., 2019 ). Studies have shown that improving the dietary nutrition level can improve the relative abundance of Lactobacillus and increase the expression of the intestinal epithelial tight junction proteins of claudin-1 and occludin ( Jahromi et al., 2016 ; Park et al., 2016 ). Reducing protein level can increase the relative abundance of Proteobacteria phylum and promote the gene expression of NF-κB associated with intestinal inflammation ( Mukhopadhya et al., 2012 ).…”

Salmonella Typhimurium ( S. Typhimurium) infection in broiler chickens threatens public health and livestock production. In this study, we explored the effects of highly nutritious (crude protein 21.8%, metabolizable energy 3.16 Mcal/kg) and lowly nutritious (crude protein 18.1%, metabolizable energy 2.98 Mcal/kg) diets on S. Typhimurium infection by altering the intestinal morphology and environment in broiler chickens. The highly nutritious diet significantly increased the body weight gain and reduced feed conversion ratio on day 1 to 21 ( P < 0.01). The highly nutritious diets promoted the intestinal villus height, crypt depth, and their ratio to improve the intestinal epithelial maturation ( P < 0.05). Highly nutritious diets significantly increased the expression of claudin-1, occludin, and NF-κB genes in the intestinal epithelium on the days of 14 and 21 ( P < 0.05). S. Typhimurium activated the expression of TLR4 , MyD88 , and NF-κB genes to cause an inflammatory response. The S. Typhimurium can increase the activity of myeloperoxidase, which cause an inflammatory response. The S. Typhimurium significantly reduced the diversity indexes of the ileal microbiota ( P < 0.05), increased the abundance of Cyanobacteria which can synthesize toxins. The highly nutritious diet group challenged with S. Typhimurium can increase the abundance of Lactobacillus in the ileum, which lead to improved intestinal health ( P < 0.05). It is concluded that increasing the nutritional level of dietary is beneficial to improve the resistance to S. Typhimurium infection by altering the intestinal bacterial community.
