This year’s Physiology & Endocrinology Program Committee selected a symposium focusing on Pregnancy Losses in Livestock for the 2020 ASAS-CSAS-WSASAS Virtual Annual Meeting. The symposium was developed to highlight the challenges faced with maintaining pregnancies in cattle and pigs. Methods are available to maximize fertilization success in livestock, but little information exists detailing ways to minimize embryonic and early fetal losses. The magnitude of pregnancy losses during the initial periods of embryo development is extensive in beef cattle and pigs, and the symposia speakers discussed the etiology of these losses, provided insights into the economic consequences of pregnancy losses, proposed developmental mechanisms that...

家畜妊娠损失：2020 年 ASAS-CSAS-WSASAS 虚拟会议生理学和内分泌学研讨会概述。

今年的生理学和内分泌学项目委员会为 2020 ASAS-CSAS-WSASAS 虚拟年会选择了一个专注于家畜妊娠损失的研讨会。该研讨会旨在强调维持牛和猪妊娠所面临的挑战。有多种方法可以最大限度地提高牲畜的受精成功率，但很少有信息详细说明如何最大限度地减少胚胎和早期胎儿损失。在肉牛和猪的胚胎发育初期，妊娠损失的严重程度在肉牛和猪中很普遍，研讨会发言人讨论了这些损失的病因，提供了对妊娠损失的经济后果的见解，提出了……
