영어 초록

The study was conducted to investigate the comparison of pregnancy rate and transferable embryos produced by genetically superior Korean cows (Hanwoo) of livestock farms. Eighteen Hanwoo donors were superovulated with gonadotropin for 4 days combined with Progesterone Releasing Intravaginal. Embryos were recovered 7 days after the second insemination by flushing the uterus with embryo collection medium. No differences were observed in the efficiency of rate of superovulation in groups A (low nutrition) and B (highnutrition) it was observed to be 100.0% and 87.5%, respectively. The mean numbers of total embryos were 10.8±3.4 and 8.9±2.5, and transferable embryos were 7.5±3.3 and 4.0±1.5 in groups A and B, respectively. The pregnancy rates after embryo transfer were 23.5%, 20.0%, C 80.0% and 55.6% in farm A, B, C, and D, respectively. In conclusion, results suggest that superovulation could be used quite effectively to raise superior Hanwooembryos. However, physical and biological condition of recipients greatly affects the rate of pregnancy.
