Fermented feed (FF) is widely applied to improve swine performance. However, the understandings of the effects of FF on the immune status and gut microbiota of lactating sows and whether probiotics are the effective composition of FF are still limited. The present study aimed to investigate the performance, immune status and gut microbiota of lactating sows fed with a basal diet supplemented with Bacillus subtilis and Enterococcus faecium co‐fermented feed (FF), with the probiotic combination (PRO) of B. subtilis and E. faecium and control diet (CON) as controls. Compared with the CON group, FF group remarkably improved the average daily feed intake of sows and the weight gain of piglets, while significantly decreased the backfat loss, constipation rate of sows and diarrhoea incidence of piglets. The yield and quality of milk of sows in FF group were improved. Besides, faecal acetate and butyrate were promoted in FF group. Additionally, FF increased the level of IgG, IgM and IL‐10 and decreased the concentration of TNF‐α in serum. Furthermore, FF reduced the abundance of Enterobacteriaceae and increased the level of Lactobacillus and Succiniclasticum, which were remarkably associated with growth performance and serum immune parameters. Accordingly, microbial metabolic functions including DNA repair and recombination proteins, glycolysis and gluconeogenesis, mismatch repair and d‐alanine metabolism were significantly upregulated, while amino acid metabolism was downregulated in FF group. Overall, the beneficial effects of FF were superior to PRO treatment. Altogether, administration of FF during lactation improved the performance and immune status, and modulated gut microbiota of sows. Probiotics are not the only one effective compound of FF.

枯草芽孢杆菌和粪肠球菌共同发酵饲料可调节泌乳母猪的生产性能，免疫状态和肠道菌群
发酵饲料（FF）被广泛应用于改善猪的生产性能。然而，关于FF对泌乳母猪免疫状态和肠道菌群的影响以及益生菌是否是FF的有效成分的了解仍然有限。本研究旨在研究以基础饮食补充枯草芽孢杆菌和粪肠球菌联合发酵饲料（FF）以及枯草芽孢杆菌和E的益生菌组合（PRO）喂养的泌乳母猪的性能，免疫状况和肠道菌群粪便并控制饮食（CON）作为对照。与CON组相比，FF组显着提高了母猪的平均日采食量和仔猪的增重，同时显着降低了仔猪的背脂损失，便秘率和腹泻率。FF组母猪的产奶量和品质得到改善。另外，FF组可促进粪便中乙酸和丁酸的分泌。此外，FF增加了血清中IgG，IgM和IL-10的水平，并降低了TNF-α的浓度。此外，FF减少了肠杆菌科细菌的丰度，并增加了乳杆菌和琥珀弹菌的水平，这与生长性能和血清免疫参数显着相关。因此，FF组的微生物代谢功能显着上调，包括DNA修复和重组蛋白，糖酵解和糖异生，错配修复和d-丙氨酸代谢，而氨基酸代谢则下调。总体而言，FF的有益效果优于PRO治疗。总之，在哺乳期施用FF可以改善母猪的生产性能和免疫状况，并调节其肠道菌群。益生菌不是FF的唯一一种有效化合物。
