Abstract
|
|
|
This study was carried out to evaluate khe accuracy of the early iliagnosis of pregnancy in dairy cows using EIK-kit of progesterone in milk and to compare the progesterone concentrations in milk with those assayed by radioimmunoassay.
1. The progesterone concentrations of the pregnant cows(2.07±0.54ng/㎖) were significantly higher than those of non-pregnant cows(1.04±0.19ng/㎖), and thereafter began to inerease and maintained high levels.
2. During 20 to 22 days after artificial insemination, the accuracy of pregnancy diagnosis from EIA-kit of progesterone were 93.7% for non-pregnant cows, and 91.6% for pregnant cows.
3. During 20 to 22 days after artificial insemination, the accuracy of pregnancy diagnosis from milk progesterone concentrations were 100% for non-pregnant cows (<2.7ng/㎖), and 92.9% for pregnant cows(≥3.2ng/㎖). The average overall accuracy of prediction for pregnant and non-pregnant cows were 96.5%.
4. Accordingly, the pregnancy diagnosis from EIA-kit of progesterone is thought to be recommendable because this early diagnostic means are simple with accurate result.
