초록

The purpose of this study was to determine the effect of bST treatment on progesteron concentration, embryo recovery and pregnancy rate following embryo transfer. Donor cows were superovulated with Folltropin-V and PGF₂ α combination method and then inseminated with frozen semen 3 times 12 hrs interval. Donor and recipient cows were assigned to control and bST group, of which was given a single injection of bST (500 ㎎, sc) at insemination or estrus detection. Embryo collection of superovulated cows were flushed nonsurgical method at 7 to 8 days after artificial insemination. (omitted)
