• Because the role of bone turnover during early to peak lactation in dairy cows is unclear, plasma levels of osteoclast- or collagen-specific bone resorption and osteoblast-specific bone formation markers from postpartum week 3 (W+3) to W+7 were compared with prepartum W-3 levels in multiparous (n=15) and primiparous (n=13) Holstein cows. The multiparous group showed a consistently low level of osteoclast-specific bone resorption markers, while collagen-specific resorption and osteoblast-specific formation markers decreased at postpartum W+7 and from W+5, respectively. In the primiparous group, the plasma levels of all three markers decreased from postpartum W+3. These results suggest that the calcium demand during the transition from early to peak lactation in dairy cows is less affected by bone turnover.
