To improve the efficiency of in vitro production of embryos with follicular oocytes in pig, the recovery rates, in vitro fertilization and development. The results obtained were as fellows: The number of oocytes recovered 37 ovary was 1,365 by aspiration, 1,884 by slicing and 3,830 aspiration post slicing, per ovary was averaged 103.5 aspiration post slicing than 30.7 by aspiration and 50.8 by slicing (P<0.05). The percentage of grade I and II oocytes recovered was 0.05∼0.2% and 1.7∼2.3% respectively(p<0.05). The fertilization rates of ejaculate and epididymis sperm was 83.0 and 83.1%. And cleavaged rate was 60.8 and 69.0% respectively(P<0.05). However, there were no significant differences between sperm sources. The clevage rates of fertilized oocyte was significantly(P<0.05) higher as B.O(92.8%) than TALP (90.1%) or mTBM (80.1%). And in vitro developed to blastocyst rates of mTBM media used for fertilization was significantly (P<0.05) higher as 12.4%, compared with the results using the media of TALP(1.6%) or B.O (0.0%). The embryos developed 2-cell stage after in vitro fertilization were co-cultured with or without POEC and BOEC in NCSU-23 and TCM-199 media. In vitro developed to blastocyst rates was NCSU-23 with POEC(2.3%) or BOEC(1.2%), but in vitro cultured in TCM-199 medium with POEC or BOEC was not developed to blastocyst. The percentage of embryos that developed to morula stage in 0, 50, 100, 200 and 250uM was 16.6, 22.0, 13.5, 19.0 and 22.0%, respectively.
