Twin pregnancies are an economically unwanted phenomenon in dairy cattle, not only because they increase pregnancy losses, but also because antibiotics usage and culling rate of the dam are also dramatically increased due to them, furthermore animal welfare issues are also affected through them. In cattle, under field conditions using an early pregnancy determination tool, the first accurate diagnosis from the pregnancy status is available from around day 28, although further confirmations of pregnancy are required. Twin pregnancy diagnosis is available either by rectal palpation or ultrasonography. The measurement of pregnancy specific proteins are also available to determine gestation, but there is still a long way to go to properly identify twin pregnancies. In this commentary, we compared our own results with the literature data in this field with a special emphasis on the clinical practices.
双胎妊娠在奶牛养殖中是一种经济上不受欢迎的现象，这不仅是因为它们会增加妊娠损失，还因为它们会大幅增加抗生素的使用量以及母畜的淘汰率，此外还会影响动物福利问题。在牛群中，在田间条件下使用早期妊娠诊断工具，大约在第28天可首次准确诊断妊娠状态，不过仍需要进一步确认妊娠情况。双胎妊娠诊断可通过直肠触诊或超声检查进行。测量妊娠特异性蛋白质也可用于确定妊娠，但要准确识别双胎妊娠仍有很长的路要走。在这篇评论中，我们将自己的结果与该领域的文献数据进行了比较，特别强调了临床实践。
