Abstract
The purpose of this study was to determine the effect of bST treatment on embryo recovery and pregnancy rate following embryo transfer. Donor cows were superovulated with Folltropin-V and PGF$_2$$\alpha$ 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 mg, im) at insemination or estrus detection. Embryo collection of superovulated cows were flushed nonsurgical method at 7 to 8 days after artificial insemination. The percentare and Mean$\pm$S.E. of transferable embryo was not significantly different between control and bST treatment (72.8%/5.9$\pm$4.5 vs. 83.7%15.1 $\pm$ 1.6). The percentage and Mean$\pm$S.E. of transferable embryo in non-summer season was significantly higher than in summer (81.8%/5.4$\pm$2.1 vs. 68.7%14.774.6; P<0.05). The pregnancy rate after embryo transfer in bST treatment was significantly higher than in control (64.0 vs. 47.1%; P<0.05). There was no significant difference in pregnancy rate between summer and non-summer (51.6 vs. 61.5%; P>0.05). The results indicated that InST treatment in recipient cows could improve the efficiency of transferable embryo production and pregnancy rate after embryo transfer, and non-summer season may be better far superovulation treatment and embryo transfer.
