The effects of in vitro maturation and sperm treatment condition on the in vitro fertilization (IVF) and developmental capacity of bovine oocytes were investigated and the development of embryos was compared under the 2 different co-culture system, with GC or BOEC. The cultured embryo to 16 cell or morula wre transferred into recipients or frozen by 2 different freezing method. The results obtained were summarized as follows; 1. In vitro maturation rates of vovine follicular oocytes cultrued in TCM199 with 10% FCS or ECS were 64.0% and 72.7%, but the case of addition of 10% FCS or ECS to TCM199 co-cultured with granulosa cells were 81.3% and 84.0%, respectively. IVM rate of three TCM199 added to granulosa cells was higher than that of media without granulosa cells. 2. When bovine follicular oocytes were matured in TCM199 with 10% FCS and GC and then fertilized in vitro by sperm treated with caffeine, embryo developments of bovine oocytes co-cultured with BOEC were 38.4% and 51.4%, respectively. But those of bovine oocytes co-cultured with GC were 52.2% by sperm treated with caffeine-heparin. 3. Cleavage rates of bovine oocytes cultured with 10% FCS alone and fertilized in vitro by sperm treated with caffeine-heparin was 33.0%. 4. When bovine follicular oocytes were matured in TCM199 with 10% FCS and GC, embryo developments of bovine ooctyes co-cultured with BOEC of GC were 46.0% and 50.2%, respectively. 5. When bovine follicular oocytes were matured in TCM199 with 10% ECS and GC, embryo developments co-cultured with BOEC or GC were 45.2% and 51.4%, respectively. 6. When Korean Native cow's follicular oocytes matured in TCM199 with 10% FCS and GC, embryo developed co-cultured with BOEC or GC were 45.2% and 51.4%, respectively. 6. When Korean Native cow's follicular oocytes matured in TCM199 with 10% FCS and GC, embryo developments of the bovine oocyte co-cultured with BOEC and GC were 41.8% and 60.1%. But with FCS 10% those of the bovine oocytes co-cultured with BOEC and GC were 42.0% and 48.4%, respectively. 7. When Holstein's follicular oocytes were matured in TCM199 with 10% ECS and GC, embryo developments fo the bovine oocytes co-cultured with BOEC and GC were 50.0% and 57.7%, but with ECS 10% those of the bovine oocytes co-cultured with BOEC and GC were 52.2% and 56.5%, respectively. 8. The viability of frozen-thawed embryos ranged from 60~80% and those of frozen-thawed embryos from vitrification was lower than that from conventional metiod. 9. The selected fresh embryos were transferred nonsurgically to 7 recipients but did not result in pregnancy.
