Parturition induces changes in brush use. (a) Latency to use the brush (mean ± SE) on days before and after calving (n = 26). (b) Duration of brush use (mean ± SE) on days before and after calving in primiparous cows (n = 26). Cows were progressively habituated to the testing routine potentially explaining the progressive decrease in latency and increase in brush use over the prepartum period. The baseline measures were obtained during the last brush test before calving. Data presented came from Experiment 1. An asterisk (*) represent a significant difference between day-7 and day 2.
