Pregnancy success represents a major issue for the economic income of cattle breeders. Early detection of pregnant and non-pregnant animals, as well as the prediction of early pregnancy failure, can influence farm management decisions. Several diagnostic tools for pregnancy are currently available. Among these, pregnancy-associated glycoproteins (PAGs) have been shown to be useful for identifying the presence of vital embryos and for pregnancy follow-up monitoring. This review presents an overview of the PAGs' functions, their pregnancy trends, and their use as a tool to improve reproductive management in bovine and other dairy livestock, such as small ruminants and buffalos.
妊娠成功率是影响养牛户经济收入的一个主要问题。早期检测怀孕和未怀孕的动物,以及预测早期妊娠失败,会影响农场的管理决策。目前有几种用于检测妊娠的诊断工具。其中,妊娠相关糖蛋白(PAGs)已被证明可用于识别有活力胚胎的存在以及进行妊娠后续监测。本文综述了PAGs的功能、它们在妊娠期间的变化趋势,以及它们作为一种工具在改善牛和其他奶牛类家畜(如小型反刍动物和水牛)繁殖管理方面的应用。
