Abstract

Milk progesterone were taken from dairy cows in Chiang Mai province on days 22, 42 and 64 postbreeding. Milk progesterone concentration was measured by radioimmunoassay (RIA) method. The milk samples were obtained from cross-bred cows (Native x Holstein-Friesian) with Holstei- Friesian blood ranging from 50 to over 80 percent. Mean milk progesterone concentration of nonpregnant cows on days 22,42 and 64 after insemination were 4.25, 3.70 and 3.58 ng/ml respectively. Among pregnant groups, the average milk progesterone levels were 9.76, 11.47 and 11.08 ng/ml on days 22, 42 and 64 after insemination respectively. Accuracy of nonpregnant and pregnant forecast on days 22,42 and 64 after breeding were 90.9 and 82.8,50.0 and 96.4, 100 and 92.3 percent respectively. Reproductive efficiency of the cows, in terms of pregnancy rate, were 67.3 percent. This study confirm that the use of RIA provides great potential in pregnancy diagnosis and increase reproductive efficiency in dairy cows.
