Many of these malformations are reported sporadically, but a few are common, and several have important clinical implications. One example is schistosomus reflexus, which is always a challenge for veteran clinicians and often baffling to inexperienced obstetricians. The recent finding that early palpation of the amniotic vesicle can cause intestinal atresia in calves is extremely significant for dairy practitioners. Finally, there is the ethical question in breeding animals--repairing defects that are thought to be genetic, such as atresia ani, scrotal hernia, and umbilical hernia.
这些畸形中有许多是散发性报道的，但也有一些较为常见，还有几种具有重要的临床意义。一个例子是脊柱裂外翻胎儿，这对经验丰富的临床医生来说始终是一项挑战，对缺乏经验的产科医生来说常常令人困惑。最近发现，早期触诊羊膜囊会导致犊牛肠道闭锁，这对奶牛从业者极为重要。最后，在动物繁殖方面存在一个伦理问题——修复被认为是遗传性的缺陷，如肛门闭锁、阴囊疝和脐疝。
