The objective of this study was to evaluate the embryonic development ability and the appearance of blastocysts of bovine in vitro fertilized oocytes cultured in different culture media, and also to evaluate survival rate after thawing of frozen embryos by using 1.5 or 1.8M ethylene glycol(EG) with sucrose or trehalose. Fertilized oocytes were divided into three groups; i ) monolayer of cumulus /granulosa cell prepared by TGM 199+5% calf serum(TGM199), ii)GRlaa+5% CS, iii)SOF+5% CS, and they were cultured after insemination for 9 days, at 39˚C, under 5% $CO_2$ in air, but SOF+5% CS was cultured at 39˚C, under 5% 02, 5% GO2, 99% N2. Blastocysts derived from GRlaa + 5% CS on day 7~8 after insemination were frozen by using 1.5M EG or 1.8M EG with/without 0.2M sucrose or O.1M trehalose. The development rate of blastocysts on day 7 after insemination in SOF+5% CS was significant higher than in TCM199 or CR1aa(P<0.05). The appearance rate of blastocysts on day 7-8 after insemination was higher than in TCM199, when fertilized oocytes were cultured in GRlas or SOF. The survival rate of frozen blastocysts after thawing tended to increase, when blastocysts were frozen by using 1.8M EG with 0.2M sucrose or O.1M trehalose. These results indicated that SOF or CRlaa media with amino acids was superior to TCM199 with monolayer in terms of blastocyst development in culturing of in vitro fertilized bovine nocytes, and sucrose or trehalose was supposed to prevent embryos from the freezing shock.
