摘　　要：羔羊依靠出生后吸收初乳中的免疫球蛋白获得被动免疫力,成功建立被动免疫是降低羔羊哺乳期患病率和死亡率,获得良好生长性能的重要保障。随着羊产业规模化推进和母羊产羔数提高,被动免疫失败导致羔羊死亡率升高、患病率增加和生长性能降低已成为羔羊健康培育的瓶颈问题。本文从羔羊被动免疫建立过程、影响因素和检测方法 3个方面进行综述,为通过提高羔羊被动免疫成功率保障羔羊哺乳期健康提供指导。Because of the special placental structure of ewes, lambs cannot obtain antibodies from their mothers. Obtaining immunoglobulins from colostrum is an important guarantee for establishing passive immunity, resisting diseases and obtaining good growth performance during lactation. In this paper, the establishment process, influencing factors and detection methods of passive immunization of lambs were reviewed, aiming at providing guidance for improving the success rate of passive immunization of lambs to ensure the health of lambs during lactation.
