한국어 초록

본 연구는 제주도의 흑우에서 다배란을 유기한 후 발정기 동안 혈중 호르몬의 농도 검사, 혈액 생화학 검사, 체내 수정란 회수율 등을 관찰하였다. FSH를 4일간 8회 50 mg씩 주사하여 다배란을 유기하였다. 성호르몬의 측정은 radioimmunoassay (RIA)법으로 측정하였으며 혈액 생화학치는 자동혈청 분석기로 측정하였다. 인공 수정 후 7일에 수정란을 비외과적 방법으로 회수하였다. 본 연구의 결과는 다음과 같았다. 1. 혈중 호르몬의 농도를 측

영어 초록

The objective of this study was to determine changes in serum hormone concentrations, blood chemical values and recovery rate of in vivo embryos during the estrous cycle following super-ovulation treatments in Jeju black cows. Superovulation was induced by subcutaneous administration of FSH twice a day for 4 days. Serum hormones were assayed by radioimmunoassay (RIA) and blood chemical values were analyzed by blood analyser system. Embryos were collected from all treated black cows using nonsurgical technique on day 7 after artificial insemination (AI). The results of this study were summarized as follows: 1. The progesterone concentrations were at day -11 and at day 0 (Day 0 is the first day of AI). The estradiol concentrations were at day -11 and at day 0. The lowest level of progesterone was measured at day 0. The highest levels of estradiol was measured at day 0. 2. The blood chemical values of treated black cows were no significant differences in normal cow values. 3. Sixty two embryos were collected in 12 black cows. Among the collected embryos, 37 embryos (59.7%) could be transferred into recipients. These results would be used as the basic informations for changing patterns of hormonal level and blood biochemistry in Jeju black cow with superovulation.
