Summary: | We investigated the effect of body condition loss from the dry to near calving periods on the subsequent body condition change, the occurrence of postpartum diseases, the serum metabolic parameters total cholesterol, triglyceride, glucose, and urea nitrogen and the number of days to first breeding after calving in Holstein dairy cows. Body condition scoring (using a 5-point scale with quarter-point divisions) was performed on 67 pregnant Holstein dairy cows. Cows were scored once for body condition during the dry period (prepartum day 35±16), near calving (postpartum day 5±4), and subsequently at months 1 (±day 4), 2 (±day 5), 3 (±day 5), and 4 (±day 4) of lactation. At the same time, blood samples were collected to evaluate serum total cholesterol, triglyceride, glucose and urea nitrogen concentrations. Cows were categorized based on body condition loss from the dry to near calving periods into two groups: the moderate condition loss group (0–0.75 points,
n=41), or the marked condition loss group (1.0–1.5 points,
n=26). Regular reproductive health examination was conducted by the same investigator once a week. The marked condition loss group lost more body condition (
