  • Maple Syrup and Bacillus velezensis based Supplement: in Vivo Study of the Impact on Growth Performance, Microbiota Composition, and Metabolic Activity in Weaned Piglets.

    Gautier Decabooter, Luca Lo Verso, Frederic Guay 他 · Current microbiology · 2025

    Post-weaning piglets often face digestive challenges and growth setbacks due to gut microbiota imbalances and increased susceptibility to infections and diarrhea. Various alternatives to antibiotic growth promoters have been proposed, including synbiotic supplements. Maple syrup is a source of prebiotic compounds, while Bacillus velezensis FZB42 is a nonpathogenic microorganism with probiotic pote…

  • L-theanine as a sustainable feed additive: Evaluating impacts on animal health and production efficiency.

    Shengjun Wu, Xiaona Cui · Microbial pathogenesis · 2026

    The non-protein amino acid L-theanine derived from Camellia sinensis may enhance animal productivity. Its elevated bioavailability and rapid metabolism address contemporary animal husbandry challenges. In the central nervous system, it regulates neurotransmission and promotes alpha-wave activity, which is associated with relaxation. It diminishes glutamatergic excitability and enhances gamma-amino…

  • Dietary Supplementation of a Multi-Strain Probiotic Increases Muscle Mass in Pigs.

    Shu-Hua Hsu, Ting-Yu Lee, Chao-Wei Huang 他 · International journal of molecular sciences · 2026

    Pork production is closely linked to skeletal muscle growth and anabolic processes. This study investigated the effects of dietary supplementation with a multi-strain probiotic (Lactiplantibacillus plantarum, Streptococcus thermophilus, and Bacillus subtilis) on the growth performance, carcass traits, gut microbiota, and potential signaling pathways in growing pigs. A total of 144 weaning piglets …

  • Multi-omics analysis reveals that puerarin modulates the gut-liver axis to improve hepatic health in aged laying hens.

    Xubin Du, Dong Zhao, Yuchen Zhang 他 · BMC genomics · 2026

    Age-related hepatic metabolic dysfunction significantly impairs the health and productivity of laying hens. Puerarin (Pue), a natural isoflavone, exhibits diverse pharmacological activities relevant to liver and gut health. Our previous work demonstrated that dietary supplementation with Pue improved laying performance and egg quality, while reducing the feed conversion ratio in aged laying hens. …

  • Appetite gene expression and gut microbiota in broiler chickens with varying body weights: a new perspective on flock uniformity.

    Janghan Choi, Doyun Goo, Woo Kyun Kim 他 · Poultry science · 2026

    Flock uniformity is critical in the broiler industry to ensure consistent processing yields, optimize feed efficiency, and reduce economic losses associated with size variation. The purpose of this study was to investigate differences in appetite-related gene expression and microbiota in broiler chickens with different BW. On D 18, birds were categorized into three BW groups within a flock: small …

  • Perinatal short-chain fructo-oligosaccharide supplementation to sow affects colostrum quality, and consequently microbiota composition and performances of progeny.

    Cindy Le Bourgot, Jeroen Degroote, Agathe Roméo 他 · Journal of animal science · 2026

    Perinatal nutrition of the sow plays a decisive role in controlling gut bacterial primo-colonization in the offspring and, thereby, is an important driver of the development of piglets. Since short-chain fructo-oligosaccharides (scFOS) are known to positively modulate the gut microbiota composition and its fermentative activity, our study aimed at evaluating the effects of such supplementation to …

  • Gut health in broiler chickens fed a mixture of Hermetia illucens and Tenebrio molitor meals: does it have a key role in shaping bird performance?

    Ilaria Biasato, Talal Hassan, Davide Buzzanca 他 · Poultry science · 2026

    Insect meals are promising sustainable protein sources for poultry, but comprehensive insights into their effects on gut health and growth performance are lacking. This study is the first to elucidate relationships between gut health parameters and performance in broilers fed Hermetia illucens (HI) and Tenebrio molitor (TM) meals at 5% or 10% inclusion levels, singly or in a 1:1 combination. A 37-…

  • Effects of recombinant Xylanase Xyn1m on growth performance, Intestinal morphology, and bacterial community structure in broilers.

    Mengjian Liu, Tingting Fu, Shaohua Zhai 他 · Poultry science · 2026

    This study evaluated the effects of recombinant xylanase Xyn1m, derived from Fibrobacter succinogenes and expressed in Pichia pastoris, on growth performance, intestinal morphology, and gut microbial characteristics in broilers. A total of 144 one-day-old broilers were randomly allocated to three treatments with 12 replicates per treatment (4 birds per replicate): a control group (basal diet), a l…

  • Effects of dietary tannins and compounds from fermentation of Saccharomyces cerevisiae on intake, productive performance, enteric methane emission, and rumen microbial diversity of lactating dairy cows.

    Amanda B Sant'Ana, Thierry Tomich, Polyana P Rotta 他 · Journal of dairy science · 2026

    The reduction of enteric methane emissions from ruminants is a central topic in research on sustainable livestock research. Feed additives targeting the rumen microbiome are among the strategies being explored to reduce methane emissions and improve nutrient efficiency. In this context, the aim of this study was to investigate the effects of an additive composed of condensed tannins and Saccharomy…

  • Intestinal microbiota-host crosstalk reveals mechanisms regulating residual feed intake in egg-type ducks.

    Zhiyu He, Xuli Chi, Shiying Ruan 他 · BMC genomics · 2026

    BACKGROUND: As an important economic trait in ducks, residual feed intake (RFI) may be influenced by the intestinal microbiota. However, the mechanisms underlying microbiota-host crosstalk remain unclear. RESULTS: We analyzed the total egg number (TEN), total egg weight (TEW), total feed intake (TFI), feed conversion ratio (FCR), and RFI of 1,370 ducks over a 32-day period. Within the high-TEW duc…
