Dairy semen code of advertising

The Dairy Semen Code of Advertising aims to ensure that UK farmers are provided with clear, relevant, up-to-date and easily comparible data when making their breeding decisions. 

The code is a voluntary scheme which breeding companies promoting bulls to UK dairy farmers can sign up to. 

This is achieved through companies abiding by the Dairy Semen Code of Advertising, where a full list of companies participating in the scheme can be found.
