The collection of gametes from recently deceased domestic and wildlife mammals has been well documented in the literature. Through the utilization of gametes recovered postmortem, scientists have successfully produced embryos in 10 different wildlife species, while in 2 of those, offspring have also been born. Thus, the collection of gametes from recently deceased animals represents a valuable opportunity to increase genetic resource banks, obviating the requirement for invasive procedures. Despite the development of several protocols for gamete collection, the refinement of these techniques and the establishment of species-specific protocols are still required, taking into account both the limitations and the opportunities. In the case of wildlife, the optimization of such protocols is impeded by the scarcity of available animals, many of which have a high genetic value that must be protected rather than utilized for research purposes. Therefore, optimizing protocols for wildlife species by using domestic species as a model is crucial. In this review, we focused on the current advancements in the collection, preservation, and utilization of gametes, postmortem, in selected species belonging to Equidae, Bovidae, and Felidae, both domestic and wildlife.
从近期死亡的家养和野生哺乳动物中采集配子，这在文献中已有充分记载。通过利用死后回收的配子，科学家已成功在10种不同的野生动物物种中培育出胚胎，其中有2种还诞生了后代。因此，从近期死亡动物中采集配子是增加遗传资源库的宝贵机会，无需进行侵入性操作。尽管已经开发了几种配子采集方案，但仍需要完善这些技术并建立针对特定物种的方案，同时要考虑到局限性和机遇。对于野生动物而言，此类方案的优化受到可用动物稀缺的阻碍，其中许多动物具有很高的遗传价值，必须加以保护而非用于研究目的。因此，以家养物种为模型来优化野生动物物种的方案至关重要。在本综述中，我们重点关注马科、牛科和猫科家养及野生动物在死后配子采集、保存和利用方面的当前进展。
