摘要
Abstract
Objective:To investigate the relationship between the developing rate and the developmental capacity of goat in vitro fertilized embryos to lay the foundation for further exploration of the influencing factors of mammalian embryonic devel opmental capacity. Methods: The experiments were carried out by comparing the further developmental capacity of goat in vitro fertilized embryos overstepping the first cleavage and development-block stage at different time points. Results: It was more difficult to overcome the embryonic development-block for the 2-cells embryos formed after 42 h than that formed with in 36 h after co-incubating in vitro matured oocytes with sperms. And the morula formation rate of the embryos overstepping development-block stage within 78 h was significantly higher than that overstepping development-block stage after 84 h after co-incubating matured oocytes with sperms. Conclusion: The time of overstepping the first cleavage and embryonic develop ment-block stage has a very significant impact on the subsequently developmental capacity of goat in vitro fertilized embryos.关键词
