For the great majority of British dairy farmers, cows graze outdoors during the summer and stay under cover during the winter. Some dairy cows stay indoors throughout the year.

Whatever system of housing is used, compliance with the Assured Dairy Farms (ADF) assurance scheme requires all dairy farmers to ensure that their buildings and management systems enable their cows to enjoy the Farm Animal Welfare Council's 'Five Freedoms' that define good welfare.
