Nature and potential functions of chemical signals involved in the process of pregnancy recognition in cattle are discussed. The array of prostaglandins, steroid metabolites, and proteins produced by the conceptus and endometrium are described and collated with histological and physiological responses of the uterus and ovary that lead toward maintenance of the corpus luteum. Advances during the last 10 yr partially have identified the conceptus-endometrial-ovarian signal sequence that is associated with maternal recognition of pregnancy in cattle. Final evaluation of the control system should permit investigators to improve embryo survival and augment further the impact of embryo manipulation to improve genetic merit of the cattle population.
本文讨论了参与母牛妊娠识别过程的化学信号的性质和潜在功能。描述并整理了由孕体和子宫内膜产生的一系列前列腺素、类固醇代谢物和蛋白质，并将其与子宫和卵巢的组织学及生理反应进行对照，这些反应有助于维持黄体。过去10年的研究进展已部分确定了与母牛母体妊娠识别相关的孕体-子宫内膜-卵巢信号序列。对该控制系统的最终评估应能使研究人员提高胚胎存活率，并进一步增强胚胎操作对提高牛群遗传品质的影响。
