生殖浪费是所有畜牧生产效率低下的一个主要原因，其中胚胎死亡率占了大部分。因此，欧洲共同体委员会鼓励组织一次关于农场动物胚胎死亡率的研讨会，该研讨会于 1984 年 12 月 11 日至 12 日在布鲁塞尔举行。本书包含该研讨会上提出的论文、讨论和最终总结的文本。作为研讨会的背景，描述了农场动物胚胎丢失的程度和时间。然后特别考虑了迄今为止已知与妊娠建立有关的各种机制和信号，包括胚胎和子宫来源的信号。概述并讨论了胚胎死亡的可能原因，包括生理、内分泌、遗传和免疫学因素。最后的总结包含研讨会的一般结论以及对该主题未来研究工作的建议。 J.M.斯里南 M.G.

Reproductive wastage is a major inefficiency in all livestock production with embryonic mortality accounting for a major portion of this loss. Accordingly the Commission of the European Communities encouraged the organisation of a seminar on embryonic mortality in farm animals which was held in Brussels on the 11th and 12th of December 1984. This book contains the text of the papers, discussions and final summary presented at that Seminar. As a background to the Seminar, the extent and timing of embryonic loss was described for farm animals. Particular consideration was then given to the various mechanisms and signals, both embryonic and uterine in origin, that are so far known to be involved in the establishment of pregnancy. Possible causes of embryonic death including physiological, endocrinological, genetic and immunological components were outlined and discussed. The final summary contains general conclusions from the Seminar and recommendations for future research work on this topic. J.M. Sreenan M.G.
