초록

This study was carried out to investigate the effect, range of practice, and propriety for diagnosis of early non-pregnancies and reproductive disorders by dairy cows' milk progesterone analysis used EIA-kit of home products. The results were summarized as follows : 1. During 2 to 6 months after artificial insemination, the results of milk progesterone measurement by Home-kit and Auto ELISA reader-kit with pregnant dairy cows(152 heads) certified by rectal palpation were revealed, in Home-kit, 145 heads(95.4%) of positive reaction, 7 heads(4.6%) of quasi-positive, and 0 heads(0%) of negative among 152 heads and, in Auto ELISA reader-kit, 152 heads(100%) of positive reaction among 152 heads. 2. During 19 to 22 days after artificial insemination, the results of milk progesterone measurement by Home-kit, and thereafrer during 50 to 90 days after that, the results of pregnant test by rectal palpation were summarized as follows : 147 heads(82.1%) among 179 heads of positive reaction by Home-kit and 5 heads(31.3%) among 16 heads of quasi-positive were revealed pregnant cows by rectal palpation, and 42 heads(100%) among 42 heads of negative were non-pregnant. 3. During 19 to 22 days after artificial insemination, the results of milk progesterone measurement by Auto ELISA reader-kit, and thereafrer during 50 to 90 days after that, the results of pregnant test by rectal palpation were summarized as follows : 146 heads(86.9%) among 168 heads of positive reaction by Auto ELISA reader-kit and 6 heads(28.6%) among 21 heads of quasi-positive were revealed pregnant cows by rectal palpation, and 48 heads (100%) among 48 heads of negative were non-pregnant. 4. For the accuracy of the rectal palpation, Home-kit and Auto ELISA reader-kit were used in the cows of ovarian diseases. The results were following : in the cows of reproductive disorders expected negative milk progesterone, the accuracies of rectal palpation were the same 75.5%(40 heads among 53 heads) by Home-kit and Auto ELISA reader-kit, and in the cows of reproductive disorders expected positive milk progesterone, the accuracies of rectal palpation were 82.6%(19 heads among 23 heads) and 91.3%(21 heads among 23 heads) by Home-kit and Auto ELISA reader-kit, respectively, and the general accuracies of rectal palpation were 77.6%(59 heads among 76 heads) and 80.3%(61 heads among 76 heads) by Home-kit and Auto ELISA reader-kit, respectively.
