제주마의 번식과정에 있어서 혈중 Steroid Hormone수준변화에 관한 연구 Ⅰ : 성성열과 발정주기중의 혈중 Estradiol-l7β, Progesterone수준변화 = Studies on the Blood Steroid Hormone Levels during the Reproductive Stage in Cheju Pony Mares Ⅰ. A Study on the change of estradiol-17β and progesterone levels in the plasma

다국어 초록 (Multilingual Abstract)

This study was conducted to find out the changes of estradiol-17 β and progesterone levels in the plasma occurrenoe of their puberty and during estrus cycle with 9 heads of Cheju ponies.
The estradiol-17 β and progesterone in the plasma samples were assayed by radioimmunoassay methods.
The results are as follow ;
1. The estradiol-17 β levels showed 45.4-93.6 pg/ml during 6-10 months of puberty, however it reached at peak of 162.6±73.77pg/ml at 13months with onset of estrus.
2. The progesterone levels during puberty of fillies reached peak levels of 8.28±4.52ng/ml at 14months and 0.01~0.36ng/ml during 6-10 months of puberty.
3. The estradiol-17 β and progesterone levels decreased to 75.1±27.26pg/ml and 1.96±2.25ng/ml respectively 16months o f puberty in the non-breeding season.
4. The estradiol-17 β levels during the estrus cycles showed a peak level of 107-145pg/ml at 1-7 days after the onset of estrus and decreased 66.1-91.9pg/ml at 11-17 days.
5. The progesterone levels during the estrus cyole showed less than Ing/ml at 1-7 days after the onset of estrus and a peak level of 7.5-7.7nglml at 11-15 days.
