摘　　要：[目的]探究奶水牛子宫脱垂的病因。[方法]选取53头奶水牛进行产前血浆钙、磷、丙二醛(MDA)和总抗(TAC)水平检测,根据分娩后是否发生子宫脱垂分为子宫脱垂组(M)和健康对照组(UM),并分析血浆中钙、磷及氧化/抗氧化水平与奶水牛子宫脱垂发生的关系。[结果]M组奶水牛产前1周和分娩当天的血浆钙、磷含量和氧化/抗氧化水平显著低于UM组。M组奶水牛TAC水平从产前3周到分娩当天均显著低于UM组,而MDA水平显著高于UM组。[结论]奶水牛产后子宫脱垂的发生与产前体内钙、磷水平不足和总抗氧化能力下降、过氧化产物积聚有关。[Objective] The research aimed to study the metroptosis etology of dairy buffalo.[Method] 53 dairy buffaloes were selected to detect the serum calcium,phosphorus,malondialdehyde （MDA） and the total antioxidant capacity （TAC） levels.Dairy buffaloes were divided into metroptosis group （M） and healthy control group （UM） according to the metroptosis situations of buffalo.The correlation between the content of calcium and phosphorus,oxidation/antioxidation level in plasma and the occurrence of metroptosis of buffalo was analyzed.[Resuit] The contents of calcium,phosphorus and oxidation/antioxidation level of dairy buffalo at the prenatal week and the delivering day in M group were significantly lower than that in UM group.TAC level of dairy buffalo in M group from the first three weeks to the delivering day was significantly lower than that in UM group.MDA level in M group was significantly higher than that in UM group.[Conclusion] The occurrence of postpartum metroptosis in buffalo was related with insufficient levels of calcium and phosphorus in prepartum buffalo,declined total antioxidant capacity and the accumulation of peroxide product.
