A small variation in diet influences the Lactobacillus strain composition in the crop of broiler chickens.

摘要: Abstract Feed composition has the potential to influence activities of bacteria that colonize digestive tract broiler chickens with important consequences for animal health, well being, and food safety. In this study, gut microbiota two groups raised in immediate vicinity but fed either a standard corn/soybean meal ration (corn–soy, CS) or high wheat middlings (high wheat, HW) was characterized. The findings revealed small variation feed did not distribution microbial species present community throughout tract. However, diet markedly influenced Lactobacillus strain crop. Most striking, dominant type birds on CS ( agilis R5), which comprised 25% isolates, detected HW diet. latter harbored different L. (type R1) significantly higher ratio than Several other strains were also specific particular conclusion, study showed chicken does result detectable differences can still have an impact become This finding relevance application probiotics direct-fed microbials poultry husbandry.
