Fetal mummification is an uncommon condition in most domestic species. While most often seen in multiparous and polytocous species like swine, it is also observed in monotocous species when the fetus is retained for a long time. The low prevalence of the condition may help explain the scarcity of information in the literature. To further complicate the study of this phenomenon, the physiological mechanisms that maintain pregnancy vary between species, implying different pathways for the condition. The exact outcome of early fetal mortality is unpredictable, and is influenced by several factors, including the cause of fetal mortality, differences in pregnancy between species, stage of gestation at fetal death, and number of fetuses. Based on our current knowledge of natural fetal mummification events, there are a number of prerequisites for the process of fetal mummification to occur. Examining the circumstances associated with fetal mummification can help scientists better understand the etiology and clinical situation in different species. The objective of this article is to review fetal mummification in the major domestic species: cattle, goats, sheep, horses, swine, dogs, and cats. This paper discusses the clinical situation, the most common and important etiologies, and the treatment approaches for restoring future pregnancy in the female, and where applicable, herd fertility.
胎儿干尸化在大多数家养动物中是一种不常见的情况。虽然最常出现在多胎和多产的物种如猪身上，但当胎儿长时间滞留时，在单胎物种中也会观察到。这种情况的低发生率可能有助于解释文献中信息的稀缺。使对这一现象的研究更加复杂的是，维持妊娠的生理机制因物种而异，这意味着该病症有不同的发病途径。早期胎儿死亡的确切结果是不可预测的，并且受多种因素影响，包括胎儿死亡的原因、物种间妊娠的差异、胎儿死亡时的妊娠阶段以及胎儿数量。基于我们目前对自然胎儿干尸化事件的了解，胎儿干尸化过程发生有许多先决条件。研究与胎儿干尸化相关的情况可以帮助科学家更好地理解不同物种的病因和临床情况。本文的目的是综述主要家养动物（牛、山羊、绵羊、马、猪、狗和猫）中的胎儿干尸化情况。本文讨论了临床情况、最常见和重要的病因，以及恢复雌性动物未来妊娠的治疗方法，以及在适用情况下提高畜群繁殖力的方法。
