Changes in lying behaviour and activity during the peri-parturient period in primiparous and multiparous Holstein dairy cows

Extract
The peri-parturient period is unsettling for dairy cows as they move from the dry period, through parturition, cow-calf separation and into the milking herd. The changes in physiological state, environment and social grouping through this period are likely to be particularly manifest in primiparous cows. Lactating dairy cows may be expected to spend up to 13.8 hours/day lying (Tucker and Weary, 2007), this has been shown to alter through the peri-parturient period (Huzzey et al (2005). The mean lying time for healthy cows at this farm was 11 hours day (Blackie et al, 2008).
The aim of the present study was to assess the changes in activity levels of first parity cows before and after calving as compared to their multiparous herd mates.
