It is generally accepted the gut microbiota have a profound effect on nutrition, health, and production in poultry. To deeply understand composition with dietary fiber level broilers, we evaluated cecal profiles feeding different alfalfa as additive Dahen broilers based 16S rRNA gene sequencing gas chromatography. As result, diversity was greatly accelerated level. The stimulated growth of many intestinal communities such Rikenellaceae RC9 group, Faecalibacterium, Prevotellaceae UCG 001 Ruminococcaceae 014, led to an altered microbial function Carbohydrate metabolism Genetic information processing. Meanwhile, found genera Anaerofilum Dielma were significantly correlated short chain fatty acids (SCFAs). All these results provide reference for changes key role may mediate beneficial effects broiler production, which also reflect substantial potential
