Effects of environmental change on udder health of dairy cows.
Udder health in a herd, moved from an old long-standing cowshed to a new short stall cowshed and udder health in another herd, moved from an old loose house to a new one was investigated. The stall length was too short, the insulation of the stalls and the ventilation were poor causing risks to udder health in the long-standing cowshed. After the repair of these factors udder health improved in the tying stall. A bigger milking parlour in the new loose housing cowshed caused overmilking under the first weeks after the change, and the incidence of teat tip injuries and mastitis increased.
