Abstract

The relationship between embryo and corpus luteum was studied in an experiment on Barbari goats which were made unilaterally pregnant by embryo transfer 5 days after oestrus. Two embryos were transferred to each recipient whose luteal stage was coinciding with that of the donor. The site of transfer was either ipsilateral uterine horn (group I) or contralateral uterine horn (group II). The "ipsilateral uterine horn" refers to the horn on the same side as the corpus luteum; the "contralateral uterine horn" refers to the horn on the side opposite to the corpus luteum. In all 10 recipients (5 in each group) having unilateral ovulations were used. Two of the 5 recipients, where embryos were transferred in ipsilateral uterine horn conceived and delivered two normal kids. None of the recipients where embryos were transferred in contralateral uterine horn conceived. The results of the experiment indicate that a unilateral feto-ovarian mechanism is involved in maintenance of the CL in goat.

摘要

在一项针对巴巴里山羊的实验中，研究了胚胎与黄体之间的关系。这些山羊在发情期后5天通过胚胎移植实现单侧怀孕。向每个黄体期与供体一致的受体移植两个胚胎。移植部位要么是同侧子宫角（第一组），要么是对侧子宫角（第二组）。“同侧子宫角”指的是与黄体同侧的子宫角；“对侧子宫角”指的是与黄体相对一侧的子宫角。总共使用了10只单侧排卵的受体（每组5只）。在同侧子宫角移植胚胎的5只受体中有2只受孕并产下两只正常的羔羊。在对侧子宫角移植胚胎的受体无一受孕。实验结果表明，山羊黄体的维持涉及单侧胎儿 - 卵巢机制。
