补充资料:胎衣不下
      胎儿产出后一定时间内胎衣不能排出的一种家畜产科疾病。各种家畜产后胎衣排出的正常时间为:马 1~1.5小时,牛12小时,羊4小时,猪1小时。胎衣不下主要发生于牛,奶牛的发病率约占健康分娩牛的 8.2%,饲养管理不善的奶牛场甚至可高达25~40%。此病一般虽不致引起死亡,但常可引起子宫内膜炎和不孕,迫使有些母牛被提早淘汰。
  
  牛胎盘组织的构造型式是常发本病的原因。牛的胎盘组织多属上皮绒毛膜和结缔组织绒毛膜混合型,胎儿胎盘和母体胎盘联系紧密,当产后子宫收缩无力时,二者不能分离,就导致胎衣不下。引起产后子宫收缩无力的因素有妊畜运动不足、过度肥胖,饲料中缺乏钙盐等矿物质或维生素,胎儿过多或过大引起子宫过度扩张,以及由难产导致的子宫肌疲劳等。流产后孕酮含量仍高、雌激素不足且胎盘组织联系仍紧密,也易引起此病。此外,胎盘受到感染,胎儿胎盘和母体胎盘发生愈着,也是胎衣不下的原因。
  
  常见的全部胎衣不下病例(有一部分胎衣挂在阴门外面)较易作出诊断;部分胎衣不下因未排出的这一部分残?粼谧庸?,从外部不易发现,较难诊断。保守疗法是用胶囊把抗菌药(如氯霉素或土霉素0.5~1.0克的胶囊剂)放进子宫粘膜和胎衣之间,隔日 1次,共1~3次,防止胎衣腐败,等待自行排出,这样对以后的受胎率影响不大。手术疗法是用手伸进子宫内,轻柔地从母体胎盘上剥下胎衣;在子宫颈尚未缩小的情况下可试用此法。
