Abstract: To explore the effects of resveratrol on reproductive performance，lactation performance of sows and immunity of piglets，48 healthy sows with the same parity in the late pregnancy stage were selected and randomly divided into 4 groups（12 sows per group）. The experimental period lasted from 7 days before delivery to 21 days after delivery.The control group was fed a basal diet，while the experimental groups were fed the basal diet supplemented with 100，200，and 300 mg/kg resveratrol（Resv‑1，Resv‑2，and Resv‑3 groups），respectively. The results showed that in terms of reproductive performance，compared with the control group，Resv‑2 and Resv‑3 significantly increased the number of live births by 12.67% and 12.31%，respectively，the number of healthy piglets by 14.57% and 13.53%，respectively，the litter birth weight by 14.31% and 11.88%，respectively，and decreased the number of stillbirths by 49.70% and 51.52%，respectively.In terms of lactation performance，compared with the control group，the milk fat rate of Resv‑2 and Resv‑3 groups was significantly increased by 5.91% and 6.12%，espectively，the milk protein rate was significantly increased by 18.61% and 18.30%，respectively，and the non‑fat solid content was significantly increased by 15.09% and 15.30%，respectively.Urea nitrogen content was significantly decreased 31. 51% and 31. 19%，respectively.For immunoglobulin content，compared with the control group，the IgG content of Resv‑2 and Resv‑3 groups was significantly increased by 10.14% and 8.74% in sows，and significantly increased by 25.03% and 24.22% in piglets，respectively. In terms of antioxidant capacity，compared with the control group，the glutathione peroxidase activity of piglets in Resv‑2 and Resv‑3 groups increased significantly by 25.80% and 22.67%，respectively，the superoxide dismutase activity increased significantly by 23.40% and 21.47%，espectively，the total antioxidant capacity increased significantly by 41.05% and 43.16%，respectively，and the malondialdehyde content decreased significantly by 24.70% and 23.36%，respectively. In terms of inflammatory factors，compared with the control group，the serum IL‑1β levels of piglets in Resv‑2 and Resv‑3 groups were significantly reduced by 13.96% and 15.08%，respectively.The IL‑6 was significantly reduced by 20.52% and 19.71%，respectively.The TNF‑α was significantly reduced by 16.31% and 20.31%，respectively，and the IL‑10 content was significantly increased by 35.22% and 35.52%，respectively.In conclusion，dietary supplementation of resveratrol for late pregnancy and lactation sows can improve their reproductive and lactation performance，enhance the antioxidant capacity and immunity of piglets，among which the supplementation levels of 200 mg/kg and 300 mg/kg exhibit relatively significant effects.

摘要： 为探究白藜芦醇对母猪繁殖性能、泌乳性能及仔猪免疫力的影响，选取48头胎次相同、妊娠后期健康母猪，随机分为4组（每组12头），试验期为产前7 d至产后21 d。对照组饲喂基础饲粮，试验组分别在基础饲粮中添加100、200、300 mg/kg白藜芦醇（Resv-1、Resv-2、Resv-3组）。结果表明，在繁殖性能方面，与对照组相比，Resv-2、Resv-3产活仔数分别显著提高12.67%、12.31%，产健仔数分别显著提高14.57%、13.53%，初生窝质量分别显著增加14.31%、11.88%，死胎数分别显著降低49.70%、51.52%。在泌乳性能方面，与对照组相比，Resv-2、Resv-3组乳脂率分别显著提高5.91%、6.12%，乳蛋白率分别显著提升18.61%、18.30%，非乳脂固体含量分别显著提高15.09%、15.30%，尿素氮含量分别显著下降31.51%、31.19%。对于免疫球蛋白含量，与对照组相比，Resv-2、Resv-3组免疫球蛋白G含量在母猪中分别显著提升10.14%、8.74%，在仔猪中分别显著提升25.03%、24.22%。在抗氧化能力方面，与对照组相比，Resv-2、Resv-3组仔猪谷胱甘肽过氧化物酶活性分别显著增加25.80%、22.67%，超氧化物歧化酶活性显著提高23.40%、21.47%，总抗氧化能力分别显著提升41.05%、43.16%，丙二醛含量分别显著降低24.70%、23.36%。在炎症因子方面，与对照组相比，Resv-2、Resv-3组仔猪血清白细胞介素-1β含量分别显著降低13.96%、15.08%，白细胞介素-6含量分别显著降低20.52%、19.71%，肿瘤坏死因子-α含量分别显著降低16.31%、20.31%，白细胞介素-10含量分别显著提高35.22%、35.52%。综上，妊娠后期及哺乳期母猪饲粮中添加白藜芦醇可改善其繁殖、泌乳性能，提升仔猪抗氧化力与免疫力，其中以200、300 mg/kg的添加剂量效果较为显著。
