Background Baicalin and probiotic cocktails are promising feed additives with broad application prospects. While known to enhance intestinal health, the potential synergistic impact of combining baicalin on gut health broiler chickens remains largely unexplored. Therefore, this study aims investigate influence combined administration composition ileal cecal microbiota in elucidate underlying mechanisms responsible for health-promoting effects. Results A total 320 1-day-old male Arbor Acres broilers were divided into 4 groups, each 8 replicates 10 chicks per replicate. Over a period 42 d, birds fed basal diet or same supplemented 37.5 g/t (BC), 1,000 (PC), combination both BC (37.5 g/t) PC (1,000 g/t). The results demonstrated that + exhibited positive effects, enhancing morphology, immune function, barrier function. This was evidenced by increased VH/CD ratio, sIgA levels, upregulated expression occludin claudin-1 ( P < 0.05). 16S rRNA analysis indicated potentiated effects BC, particularly ileum, where significantly α-diversity microbiota, altered its β-diversity, relative abundance Flavonifractor 0.05), flavonoid-metabolizing bacterium. Furthermore, positively correlated chicken ileum crypt depth had limited effect structure, group very similar microbial PC, suggesting at distal end overshadowed those BC. Conclusions We enhancement regulation cocktails. Probiotic enhanced accelerated metabolism thereby influencing structure. elucidates interaction mechanism between plant extract within host microbiota. These findings provide compelling evidence future development additive combinations.

Metabolic disorders in maternal generation during the late egg-laying period have adverse effects on neonatal development. The study was conducted to clarify of feeding hawthorn-leaf flavonoid (HF) microbial community and intestinal development chicks. Breeder hens were fed a basic corn-soybean diet, while treatment groups supplemented with 30 or 60 mg/kg HF. offspring chicks divided into CON, LHF, HHF according treatments.

The study investigated the effects of dietary probiotic dual-strain Bacillus subtilis on production performance, intestinal barrier parameters, and microbiota in broiler chickens. In a randomized trial, male chickens were allocated into 3 groups, control group (basal diet), BS300 diet with 300 mg/kg B. subtilis), BS500 500 subtilis). inclusion significantly reduced feed conversion ratio by 4.55% during starting phase. Both supplementation increased jejunal villus height (by 17.89% 24.8%, respectively) decreased crypt depth 27.2% 31.9%, day 21. addition elevated gene expression occludin 35. Moreover, enhanced cytokine levels immunoglobulins both serum mucosa.

In this study, we investigated the effects of supplemental Glycyrrhiza polysaccharide (GCP) on growth performance and intestinal health weaned piglets. Ninety piglets at 28 days age were randomly allocated to three groups with five replicates per treatment. Piglets fed following diets for days: (1) CON (control group), basal diet; (2) G500, + 500 mg/kg GCP; (3) G1000, 1000 GCP. The results showed that supplementation GCP increased average daily gain (ADG) decreased feed-to-gain ratio (F/G) (P < 0.05).

Abstract Multiple factors, including genetics, nutrition, and health, influence the vertical transmission of microbiota from mothers to their offspring. Recent studies have shown that avian can be passed next generation via eggshell egg albumen. However, it remains unclear whether these microbial communities are regulated by nutrition how they associated with host genotype. Chickens, controlled rearing conditions stable genotypes, provide a promising model for investigating microbiome in birds. This study aims determine genotype‐associated bacteria vertically transmitted between generations, maternal nutritional intervention soyasaponin modulates this transfer, thereby shaping chick intestinal development informing effective strategies. We established across various anatomical sites breeder hens, chicken embryos, chicks. Avian gut reproductive tract both found chicks at developmental stages.
