Abstract/OtherAbstract:
|
Milk samples were collected from 91 dairy cows on days 18, 22, and 24 postbreeding. The progesterone values of these samples were assayed, using enzyme-immuno-assay for pregnancy diagnosis. These animals were classified by nonpregnant (low progesterone values, 5 ng/ml or less) and pregnant (high progesterone values, more than 5 ng/ml). The accuracy of diagnosis on days 18, 22, and 24 postbreeding were 56%, 78%, and 79% for pregnant cows and 90%, 93%, and 93% for nonpregnant animals. The sampling date had a significant effect on diagnostic accuracy (P less than 0.05). |
