Supplementation of lactobacillus‐fermented rapeseed meal in broiler diet reduces Campylobacter jejuni cecal colonization and limits the l‐tryptophan and l‐histidine biosynthesis pathways

BACKGROUND Campylobacter jejuni (C. jejuni), a widely distributed global foodborne pathogen, primarily linked with contaminated chicken meat, poses a significant health risk. Reducing the abundance of this pathogen in poultry meat is challenging but essential. This study assessed the impact of Lacto...

Zusammenfassung:BACKGROUND Campylobacter jejuni (C. jejuni), a widely distributed global foodborne pathogen, primarily linked with contaminated chicken meat, poses a significant health risk. Reducing the abundance of this pathogen in poultry meat is challenging but essential. This study assessed the impact of Lactobacillus‐fermented rapeseed meal (LFRM) on broilers exposed to C. jejuni‐contaminated litter, evaluating growth performance, Campylobacter levels, and metagenomic profile. RESULTS By day 35, the litter contamination successfully colonized broilers with Campylobacter spp., particularly C. jejuni. In the grower phase, LFRM improved (P
