The objective of this study was to investigate the relationship between body weight, body condition score (BCS), blood urea nitrogen (BUN), glucose, cholesterol and number of transferable embryos for the purpose of improving reproductive performance in Hanwoo donors. Seventy five cows, at random stages of the estrous cycle, received a CIDR together with injection of 1mg estradiol benzoate and 50 mg progesterone, and gonadotropin treatment begann. Four days later, the animals were superovulated with a total of 28AU FSH (Antorin, 2AU = 1 ml) administered twice daily in constant doses over 4 days. On the 3rd administration of FSH, CIDR was withdrawn and 25 mg $PGF_2{\alpha}$ was administered. Cows were artificially inseminated twice after estrous detection at 12 hr intervals. The cows received $100{\mu}g$ GnRH at the time of 1st insemination. Embryos were recovered 7 days after the 1st insemination. In conclusion, cows with body weight < 400, 400~450 and > 450kg had number of transferable embryos of $4.2{\pm}1.7$, $6.1{\pm}2.7$ and $4.8{\pm}2.6$, cows with BCS <2.25, 2.25~2.75 and ${\geq}2.75$ had number of transferable embryos of $4.6{\pm}1.6$, $5.7{\pm}2.4$ and $5.1{\pm}2.7$ respectively. These data indicate that a body weight and BCS for superovulation of CIDR-treated Korean native cows does not affect the embryo yield.
