초록

본 연구는 총 4두의 삵에서 발정기와 비발정기, 임신기와 비임신기 동안의 분변에서 steroid metabolic materials를 추출한 후, TR-FIA kit를 이용하여 estradiol과 progesterone의 농도를 측정하였다. 발정기간 (2월) 중 estradiol 농도의 최저는 평균 $4.02{\pm}1.9$ng/g 이었고, 최고는 평균 $86.01{\pm}35.2$ng/g (dry fecal weight) 이었다. 비발정기(11월)의 최저는 평균 $4.42{\pm}1.32$ng/g 이었고, 최고는 평균 $15.62{\pm}6.84$ng/g 이었다. 임신기 (3월) 중 progesterone농도의 최저는 평균 $427{\pm}24.49$ng/g 었고, 최고는 평균 $1490{\pm}265.27$ng/g 이었다. 비임신기 (11월)의 progesterone의 최저는 평균 $71.25{\pm}29.61$ng/g 이었고, 최고는 평균 $291.75{\pm}90.30$ng/g 이었다. 위의 결과에 따라 삵에서 TR-FIA에 의한 분변내 steroid hormone 의 측정은 발정과 임신에 관련된 난소활동을 비 침습적으로 평가하기 위한 적절한 방법으로 판단되었다. 본 연구는 삵과 같이 접근이 어렵고 멸종위기에 처한 야생동물의 사육관리의 효율화와 번식계획의 수립에 도움이 될 것이다.

This study, conducted with four leopard cats (Prionailurus bengalensis), used time-resolved fluoroimmunoassay (TR-FIA) to analyze estradiol and progesterone concentrations in fecal samples. We measured fecal samples taken during estrus period, diestrus period, pregnancy and non-pregnancy period. During estrus (February), the mean minimum estradiol concentration was $4.02{\pm}1.9$ng/g, and the mean maximum was $86.01{\pm}35.2$ng/g (dry fecal weight). During diestrus (November), the mean minimum estradiol concentration was $4.42{\pm}1.32$ng/g and mean maximum was $15.62{\pm}6.48$ng/g (dry fecal weight). Midgestation (April), the mean minimum progesterone concentration was $427{\pm}24.49$ng/g and the mean maximum was $1490{\pm}265.27$ng/g. During non-pregnancy (November), the mean minimum progesterone concentration was $71.25{\pm}29.61$ng/g and the mean maximum was $291.75{\pm}90.30$ng/g. These results suggest that steroid hormone analysis of feces using TR-FIA is a valid method for noninvasively determining ovarian activity associated with estrus and pregnancy in leopard cats. This study will contribute to building breeding management and reproductive plans for endangered species.
