It is an offence for an occupier to permit a bull to be at large in a field or enclosure crossed by a public right of way except where:
The recognised dairy breeds are: Ayrshire, British Friesian, British Holstein, Dairy Shorthorn, Guernsey, Jersey and Kerry.
The Health and Safety Executive (HSE) regularly investigate incidents involving cattle and members of the public on rights of way and report that most arise when suckler cows and calves are at large in fields. The HSE provide a summary report and guidance for the public and for farmers in the HSE Agriculture Information Sheet.
The guidance also includes useful information as to the form and contents of signs that could be used to indicate the presence of animals.
