We carried out the image analysis of the ovary with the somascope, the progesterone concentration measurement and blood biochemical profile from postpartum to reopening estrus excitement regularly. Cows which showed heat within 60 days after childbirth were classified early recurrence cow group. Anestrus cows or heat recurred after 61st were recurrence delay cow group. And I weighed the test result of both crowds. As a result, glutamic oxaloacetic transaminase (GOT) was high, and the recurrence delay cow group showed the tendency that blood urea nitrogen (BUN), total cholesterol (TCHO) were low at the second week of postpartum. The days of reopening heat and a multiple correlation coefficient with BUN / TCHO / GOT were 0.49 at the second week of postpartum.
