Abstract

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 $3.0\~3.9\;(10.8\%)$. The pregnancy and abortion rates from the estrus type, corpus luteum, uterine size and uterine hem were not differ among treatment groups.

본 연구는 임상 조건하에서 수정란이식의 효율성 증대를 위하여 수란우 측면의 산차, 체점수(BCS), 발정 발현과 유도, 황체 형태, 자궁 크기 및 자궁각 위치가 체외수정란이 이식된 수란우의 임신과 유산에 미치는 효과를 검토하였다. 미경산우의 임신율$(43.5\%)$이 경산우$(33.6\%)$에 비하여 유의하게 높았으나, 유산율$(12.6\;vs.\;7.5\%)$은 유사한 경향이었다. BCS에 따른 임신율은 차이가 없었으나 유산율은 BCS 3.0 미만군$(55.6\%)$이 $3.0\~3.9$군 $(10.8\%)$에 비하여 유의하게 높았다. 수란우의 발정 발현과 유도 방법, 황체 형태, 자궁 크기 및 자궁각 위치에 따른 임신율과 유산율은 유사한 경향이었다.
