摘要： 为减少产犊对母牛产后子宫健康和繁殖性能的影响,收集荷斯坦牛分娩及新生犊牛数据,分析上述因素与奶牛难产及子宫健康的相关性。结果表明,头胎、分娩体况评分<3.25或>3.75、死胎、公犊和犊牛初生重≥44.0 kg为难产风险因素;犊牛初生重≤34.0 kg和（或）死胎为胎衣不下风险因素;死胎和胎衣不下为产后子宫炎风险因素;死胎、产后子宫炎和分娩体况评分<3.25或>3.75为子宫内膜炎风险因素。

Abstract: This trial analyzed the risk factors of dystocia,retained placenta,metritis and endometritis in dairy cattle. Dystocia risk factors included heifers,cows with body condition score<3.25 and>3.75 at calving,stillbirths, bull calves and heifer calves with heavy birth weigh≥44.0kg.Rretained placenta risk factor included calf birth weight≤34.0kg,and stillbirth would add the risk.Metritis risk factors included stillbirth and retained placenta. Endometritis risk factors included stillbirth,postpartum metritis and body condition score<3.25 and>3.75 at calving.
