한우 태아 섬유아세포 유래 체세포복제수정란 이식으로 임신된 수란우가 분만예정일이 도래하였으나 분만징후가 없어 수정란이식 후 272일째에 dexamethasone 20 mg을 근육주사하고 24시간후 PG 25 mg과 estradiol 20 mg을 근육주사하여 분만유도를 실시하였다. dexamethasone 투여후 48시간만 분만징후를 나타내었으며, dexamethasone 투여후 50시간째에 40 kg의 수송아지를 견인에 의해 정상적으로 분만시켰다. 그러

This study was performed to produce Hanwoo-fetal fibroblast cell clone transferred to Holstein recipient. It was coming on the parturition but didn't show parturition signs until 272 days from the embryo transfer. For the induction of normal parturition, dexamethasone (20 mg) were injected with IM on 272 day and PG (25 mg) plus estradiol (20 mg) was injected with IM after 24hrs. Forty-eight hours after dexamethasone injection, we could find parturition signs and delivered healthy male of offspring (40 kg) about 50 hrs after it's injection. However the recipient was showed retention of afterbirth.h.
