This study was carried out to determine the effect of bovine follicular fluid(bFF), hormones, and fetal bovine serum(FBS) supplemented in the medium on the in vitro fertilization and development of bovine embryos. The ovaries were obtained from a local abattoir and placed in physiological saline kept at 30~32˚C and brought to the laboratory within 3~4 hours. The oocytes and follicular fluid were collected by aspiration from visible follicles, and the oocytes of grades I on the basis of the morphology of cumulus cells attached and the homogeneity of cytoplasmic granules were selected and used for maturation. The basal media used for oocyte maturation, fertilization and embryo development in vitro were Ham' F-10, TALP and TCM-199, respectively. The hormones supplemented in maturation medium were consisted of 35 pg /ml FSH, 10 pg /ml LH and 1 pg/mi estradiol-l7$\beta$. The bFF collected from 5~9 mm follicles was centrifuged, filtered and inactivated by heat-treatment at 56˚C for 30 min. FBS also was inactivated with the same method and kept at -20˚C until use. The embryos were co-cultured with the monolayer of bovine oviductal epithelial cells at 39˚C under 5% $CO_2$ in air for 9 days. The results obtained were summarized as follows: The fertilization rate of oocytes was found 87.4% from 10% FBS and hormones treatment for IVM, and 37.1% of these TVF embryos were developed to blastocyst stage in 10% FBS groups. Compared with this control system, the fertilization rate was decreased significantly(P<0.05) in the maturation without either FBS or hormones. These IVF embryos were developed to morula stage at the similar rate, but to blastocyst at significantly(P<0.05) lower rate in the embryo culture with or without FBS supplementation. The fertilization rate(82.9%) in hormones and 10% inactivated bFF was similar with 10% FBS and hormone groups(87.4%), but decreased significantly(P<0.05) in 20 or 30% bFF (61.0 or 66.0%), respectively. In vitro developmental competence to blastocyst stage in 10% FBS and 20% inactivated bFF(37.1% and 31.4%) was higher than in 10 or 30% inactivated bFF(20.0 or 19.2%) or 10, 20 and 30% fresh bFF(19.1, 21.0 and 17.5%) The results indicated that the in vitro fertillzation and development rate of the embryos should be improved in 10% FBS or 20% inactivated culture system and 20% inactivated bFF might be available economically for bovine oocyte maturation and embryo culture instead of fetal bovine serum.
