新疾病：母羊生殖应激及其综合征

母羊的生殖应激主要包括母羊主动应激、母羊被动应激以及胎羊宫内应激。适当的生殖应激是正常发情、维持妊娠、发动分娩、顺利哺乳的重要生理基础。但长期或过度的生殖应激，将引起母羊代谢紊乱、免疫功能损害、生殖障碍以及胎羊或羔羊发育受阻等，这一系列能造成母体健康损害的疾病和临床表现，被定义为“母羊生殖应激综合征”。本文对母羊生殖应激及母羊生殖应激综合征进行了定义，并对生殖应激理论的综合临床应用进行了探讨，为预防和治疗生殖疾病(如妊娠期毒血症、产后乏力、子宫内膜炎等)提供了理论依据。

New Disease: Ewe’s Reproductive Stress and Its Syndrome

The reproductive stress of ewes mainly includes active reproductive stress, passive reproductive stress, and fetal intrauterine stress. Appropriate reproductive stress is an important physiological basis for normal estrus, maintenance of pregnancy, initiation of parturition, and smooth lactation. However, long-term or excessive reproductive stress causes metabolic disorders, immune function damage, reproductive disorders, and fetus or lamb development retardation. This series of diseases and clinical manifestations that can cause maternal health damage has been defined as “ewe’s reproductive stress syndrome”. This paper defines ewe’s reproductive stress and ewe’s reproductive stress syndrome and discusses the comprehensive clinical application of the reproductive stress theory, which provided a theoretical basis for preventing and treating reproductive diseases (such as toxemia during pregnancy, postpartum anestrus, endometritis, etc.).
