초록

본 연구는 도축된 제주마의 난소를 이용하여 초음파 유도난포란 채취 기술을 확립하고자 난소, 난포 및 황체의 크기를 초음파상과 육안적 측정치를 비교하고자 하였다. 초음파상 측정치와 caliper를 이용한 실제 크기의 측정치 비교에서는 통계학적 차이는 보이지 않았다. 배란 직전의 난포를 조사한 결과, 초음파상에서 관찰한 것은 난소 한 개 당 평균 0.83개와 평균 크기는 2.86 m였으며, 육안으로 관찰된 것은 난소 한 개 당 평균 0.75개와 평균 크기는 2.3 cm였다. 난소 한 개 당 평균난포 수는 초음파상에서는 4.25개와 육안에서는 4.38개였다. 제주마 난소의 난포 크기 및 수를 초음파상과 육안으로 조사하였던 바, 유의적인 차이가 나타나지 않았다. 이러한 결과로 차후 초음파를 이용한 OPU와 말에서 번식 기술과 관련된 연구에 기초 정보가 제공되리라 사려된다.

The purpose of the present study was to set up basic information of size and status of ovaries by using ultrasonography to retrieve in vivo matured oocytes with ovum pick- up method. Ovaries were collected from the abattoir in Jeju in May and June which is breeding season. When the size of ovaries on ultrasonography was compared with real size measured by caliper, no significant difference was shown (p<0.05). The number of preovulatory follicles (>21mm) was investigated with ultrasonography and naked eyes. Ultrasonography group had 0.83 preovulatory follicles per ovary and naked-eye group had 0.75 preovulatory follicle per ovary and their average size was 2.86 cm and 2.34 cm, respectively. The average number of follicle was 4.25 with ultrasonography and 4.38 with naked eyes. There was no significant difference considering the size of follicle and number of follicle between ultrasonography and actual size except for the size of preovulatory follicle, suggesting that information of ultrasonography is able to use for OPU or other reproductive technology of mare.
