Abstract

The objectives of this study were (1) to determine the optimum in vitro culture conditions for in vitro fertilized bovine embryos among culture methods and (2) to investigate whether bovine fertilization and embryo development would occur in simulated microgravity conditions in vitro. In the first part of this study, the result showed that the microdrop method was the optimum culture method among groups; however, FBS supplementation did not significantly affect the bovine preimplantation embryo development in vitro. In the second part of this study, the result showed that bovine in vitro fertilization did not occur in simulated microgravity conditions. Moreover, none of the presumptive zygotes and 2-8 cell stage embryos were able to develop to further stages, while embryos cultured in standard microdrop method culture conditions developed normally.
