1999년 6월부터 2002년 4월까지 총 2년 11개월 간 전국에서 발생한 소 유조사산에 대한 임상학적 연구결과는 다음과 같았다. 1. 계절별 소 유조사산 발생은 여름에 다른 계절에 비해 많이 발생하였다. 이는 여름철의 고온 다습한 기후와 낮은 우군관리 집중도에 기인한다고 사료된다. 2. 임신우의 산차별 유조사산 발생 비율을 조사한 결과 산차가 낮은 소에서 많이 발생하였다. 이는 유조사산의 원인이 임신우의 산차수에 있기보다는 산차수가 높은경우 사육되는

영어 초록

The objective of this study was to investigate the clinical aspects on bovine abortion and stillbirth in Korea. Three hundred thirty eight bovine fetuses were collected from farms and submitted to the College of Veterinary Medicine, Seoul National University. Submitted fetuses were evaluated for season, parity and gestation stage on abortion during a 3 years period (June, 1999 to April, 2002). Out of four seasons, incidence of bovine abortion was significantly higher in summer than other seasons (P＜0.05) due to high temperature and humidity. After surveying of incidence of abortion according to parity, it was concentrated in low parity (1, 2 and 3 parity). However, this result was not caused by parity but because most of surveyed cow was low parity. For surveying the distribution of abortion incidence according to days of gestation, we divided the days of gestation into 3 stages including with early (0∼150 days), middle (151∼250 days) and late (251days∼term). Out of 319 aborted fetuses, incidences of abortion were significantly higher in the middle and late stage than early stage (P＜0.05). A high rate (75％) of stock farms did not vaccinate animals, therefore most of cows in Korea were found to have a high risk of becoming infected upon exposure to pathogens. Many of abortions occurred in stock farms where animals of other species were being bred. More studies will be needed to investigate possible linkages between bovine abortion and the breeding of other animal species.
