Stimbiotic supplementation may provide an innovative feed additive solution to accelerate the proliferation of beneficial fiber-degrading bacteria in the distal intestine and the utilization of dietary fiber. Optimal utilization of dietary fiber has multiple benefits for gut health and nutrient utilization. This study was conducted to evaluate the late gestation and lactation performance, the plasma, colostrum, and milk immunoglobulin (IgA, IgG, and IgM) concentrations, and the anti-inflammatory and antioxidant biomarkers in plasma of sows fed with or without a stimbiotic during the late gestation and lactation phase. A total of 40 sows were allocated to two treatment groups: control (CT) with no supplementation or 100 mg/kg stimbiotic (VP), with 20 sows per treatment. Sows were fed the treatment diets from d 85 of gestation to d 28 of lactation. In the results, the average daily weight gain of piglets during lactation was greater from sows fed in the VP group compared to that in the CT group ( < 0.05). The plasma concentrations of IgM at farrowing and IgG at weaning of the sows fed the diet with the stimbiotic supplementation were much higher than those in the CT sows ( < 0.05), respectively. In addition, the dietary stimbiotic increased the concentrations of IgM in the colostrum and of IgA and IgM in the milk at d 14 of lactation ( < 0.05). Plasma concentrations of malondialdehyde (MDA) on d 0 and d 28 of lactation tended to be lower in sows fed the VP diets compared with those of the sows fed the CT diets. Thus, our study indicated that stimbiotic supplementation could improve the daily weight gain of piglets and the immune function of sows in lactation.
添加合生元可能提供一种创新的饲料添加剂解决方案，以加速远端肠道中有益纤维降解细菌的增殖和膳食纤维的利用。膳食纤维的最佳利用对肠道健康和营养利用具有多重益处。本研究旨在评估在妊娠后期和哺乳期饲喂或不饲喂合生元的母猪的妊娠后期和泌乳性能、血浆、初乳和乳汁中的免疫球蛋白（IgA、IgG和IgM）浓度，以及血浆中的抗炎和抗氧化生物标志物。总共40头母猪被分配到两个处理组：不添加的对照组（CT）或100 mg/kg合生元组（VP），每个处理组20头母猪。母猪从妊娠第85天至泌乳第28天饲喂处理日粮。结果显示，与CT组相比，VP组饲喂的母猪所产仔猪在哺乳期的平均日增重更高（<0.05）。饲喂添加合生元日粮的母猪在分娩时的血浆IgM浓度和断奶时的IgG浓度分别远高于CT组母猪（<0.05）。此外，日粮中的合生元增加了泌乳第14天时初乳中IgM以及乳汁中IgA和IgM的浓度（<0.05）。与饲喂CT日粮的母猪相比，饲喂VP日粮的母猪在泌乳第0天和第28天的血浆丙二醛（MDA）浓度趋于更低。因此，我们的研究表明，添加合生元可以提高仔猪的日增重和母猪哺乳期的免疫功能。
