Abstract

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)
