This study was conducted to investigate the effects of various factors of recipients such as recipient parity, body condition score(BCS), estrus type, corpus luteum, uterine size and uterine horn, on pregnancy and abortion after transfer of in vitro produced Korean Native Cow embryos. The pregnancy rate of nulliparous (43.5%) was significantly higher than that of multiparous (33.6%), but there were no difference in the abortion rates (122.6 vs. 7.5%). There were no difference in pregnancy among the groups of BCS treatment, but the abortion rate was significantly higher in the group of below BCS 2.0~3.0 (55.6%) than the group of BCS 3.0~3.9 (10.8%).
