Background. To evaluate the biological response of the sows and their offspring with oral administration of Lactobacillus plantarum CAM6 in breeding sows, a total of 20 Pietrain breeding sows with three farrowings and their descendants were used, randomly divided into two groups of 10 sows each. Treatments included a basal diet (T0) and basal diet +10 mL biological agent containing 10⁹ CFU/mL L. plantarum CAM6 (T1). No antibiotics were used throughout the entire experimental process of this study. Results. The L. Plantarum CAM6 supplementation in sows’ feeding did not affect () the reproductive performance of the sows; however, the number of deaths for their offspring before weaning () decreased. In addition, the oral administration of Lactobacillus plantarum CAM6 in sows increased () the content of lactose, nonfat solids, mineral salts, and the density of sows’ milk, with a decrease in milk fat. Moreover, the probiotic feed orally to the sows improved the body weight () and reduced the diarrhea incidence of their offspring (). Also, the probiotic administration of sows changed () the serum concentration of Na⁺, pCO₂, and D-β-hydroxybutyrate and increased () the leukocytes, lymphocytes, and platelets in their piglets. Conclusion. Oral administration of Lactobacillus plantarum CAM6 in breeding sows improved body weight, physiological status, and the health of their offspring. And preparing the neonatal piglets physiologically is of great importance to the pig farming industry which could decrease the operational cost and medication (especially antibiotics) consumption of the pig producers.

口服植物乳杆菌 CAM6 菌株对妊娠-泌乳期母猪的影响及其对后代性能的影响

背景。为了评价母猪及其后代口服植物乳杆菌CAM6对种母猪的生物学反应，共使用20头Pietrain种母猪和3头产仔及其后代，随机分为两组，每组10头母猪。治疗包括基础饮食 (T0) 和基础饮食 +10 mL 含有 10 ⁹  CFU/mL植物乳杆菌CAM6 (T1) 的生物制剂。在本研究的整个实验过程中没有使用抗生素。结果。母猪饲喂中添加植物乳杆菌 CAM6 不影响 ()母猪的繁殖性能；然而，它们的后代在断奶前的死亡人数（)减少。此外，母猪口服植物乳杆菌CAM6 增加（)乳糖、脱脂固体、矿物盐的含量和母猪乳汁的密度，乳脂减少。此外，给母猪口服益生菌饲料可以改善体重（)并降低其后代的腹泻发病率 (）。此外，母猪的益生菌给药发生了变化（) ^{Na +}、pCO ₂和 D- β -羟基丁酸的血清浓度)仔猪的白细胞、淋巴细胞和血小板。结论。在种猪中口服植物乳杆菌CAM6 可改善其后代的体重、生理状态和健康。新生仔猪的生理准备对养猪业具有重要意义，可以降低生猪生产者的运营成本和药物（尤其是抗生素）的消耗。
