The behavioural development of Holstein-Friesian cows and calves in different housing systems was examined. There were no significant differences in calving ease between cows housed with different areas per cow and in groups or individually. 32-45% of the cows housed in groups separated themselves from the group just before calving. In the cow-calf relationship, the sensitive period in the cow was expressed for 6 hours after the first calving and increased following the next calving. This behaviour of the cow could help the new-born calf to obtain colostrum in time. The early sensitive period of the calves developed in the first 10 days after birth. Calves that had more human care during this period became easier to manage.
