Abstract: To investigate the effects of adding fermented Chinese herbal medicines（Codonopsis pilosula，Lycium barbarum，Astragalus membranaceus，Atractylodes macrocephala，Poria cocos） to the diet of lactating sows on the growth performance，blood biochemical indexes，immune function and antioxidant capacity of lactating sows and suckling piglets，and to explore its application effects in lactating sows and suckling piglets，27 Hexi black sows with similar parity，farrowing time and litter size were randomly divided into 3 groups with 3 replicates per group and 3 piglets per replicate.The control group was fed a basal diet，while experimental groups Ⅰ and Ⅱ were supplemented with 1.5% and 2.0% fermented Chinese herbal medicines in the basal diet，respectively.The experimental period was from the date of delivery of sows to the end of weaning day of piglets at 25 days post partum.The results showed that compared with the control group，the weaning body weight per individual and average daily gain of experimental group Ⅰ were significantly increased by 11.16% and 12.53%，respectively.The diarrhea rates of the two experimental groups were significantly decreased by 67.60% and 85.73%，respectively.In experimental group Ⅰ，the activities of alanine aminotransferase，aspartate aminotransferase and blood urea nitrogen content in the blood were significantly decreased by 35.36%，40.11% and 24.96%，respectively.The contents of glucose in experimental groups Ⅰ and Ⅱ were increased by 65.06% and 94.58%，respectively.The contents of IgG，IgA and IL⁃6 in blood of group Ⅰ were significantly increased by 28.33%，44.95% and 24.68%，respectively.The levels of IL⁃1β and IL⁃6 in group Ⅱ were significantly increased by 35.44% and 33.73%，respectively. The activity of superoxide dismutase in the blood of group Ⅰ was significantly increased by 22.32%，and the content of malondialdehyde was significantly decreased by 32.61%.In summary，adding 1.5% fermented Chinese herbal medicines to the diet of lactating sows can effectively improve the growth performance of suckling piglets，reduce diarrhea rate，and optimize some blood biochemical and immune antioxidant indicators.

摘要： 为研究泌乳母猪饲粮中添加发酵中草药（党参、枸杞、黄芪、白术、茯苓）对泌乳母猪和哺乳仔猪生长性能、血液生化指标、免疫功能和抗氧化能力的影响，探讨其在泌乳母猪和哺乳仔猪上的应用效果，将产仔胎次、时间及数量相近的27头河西黑猪分为3组，每组3个重复，每个重复3头，其中对照组饲喂基础日粮，试验Ⅰ组、试验Ⅱ组分别在基础日粮中添加1.5%、2.0%的发酵中草药，试验周期为母猪分娩之日至产后25 d仔猪断奶当天。结果表明，与对照组相比，试验Ⅰ组断奶个体质量、平均日增质量分别显著提高11.16%、12.53%，2个试验组的腹泻率分别显著下降67.60%、85.73%；试验Ⅰ组血液中谷丙转氨酶活性、谷草转氨酶活性、尿素氮含量分别显著下降35.36%、40.11%、24.96%；试验Ⅰ组和试验Ⅱ组葡萄糖含量分别提高65.06%、94.58%；试验Ⅰ组血液中IgG、IgA 及IL-6 含量分别显著提高28.33%、44.95%、24.68%，试验Ⅱ组IL-1β和IL-6水平分别显著提高35.44%、33.73%；且试验Ⅰ组血液中超氧化物歧化酶活性显著提高22.32%，丙二醛含量显著下降32.61%。综上，在泌乳母猪饲粮中添加1.5%发酵中草药，能有效通过母体改善哺乳仔猪的生长性能、降低腹泻率、优化部分血液生化与免疫抗氧化指标。
