This comprehensive review explores the complex processes of reproduction, pregnancy establishment, and pregnancy diagnostic methods in cattle, sheep, goats, swine, horses, and camelids. It provides an overview of the history of pregnancy detection and an in-depth exploration of the physiology of pregnancy in livestock. The detection of conceptus tissue and fluids, conceptus-produced hormones, and maternal responses to conceptus signals, crucial for pregnancy diagnosis, are also discussed in detail, as are emerging methods for pregnancy diagnosis in livestock species. Overall, this review emphasizes the direct impact of pregnancy diagnosis and efficient pregnancy management for profitability of livestock enterprises.
这篇综述探讨了牛、羊、山羊、猪、马和骆驼科动物的繁殖、妊娠建立及妊娠诊断方法等复杂过程。它概述了妊娠检测的历史，并深入探讨了家畜妊娠的生理学。对于妊娠诊断至关重要的孕体组织和液体、孕体产生的激素以及母体对孕体信号的反应的检测也进行了详细讨论，家畜物种妊娠诊断的新兴方法同样如此。总体而言，这篇综述强调了妊娠诊断和高效妊娠管理对畜牧企业盈利能力的直接影响。
