Welcome to DairyCo genetic evaluations homepage

DairyCo Breeding+ is the independent source for the latest UK genetic evaluation results, explanations of the indices and statistical analysis of all major breeds in the United Kingdom.

Since December 2012 DairyCo, along with our Genetics Advisory Forum which is made up of farmers, breed societies, breeding companies, scientists and milk recording companies, have been undertaking a review of the current Profitable Lifetime Index and considering the future genetic needs of the UK dairy industry. As of August 2014 this has resulted in the launch of a revised Profitable Lifetime Index (£PLI), click here for details, and the introduction of a new Spring Calving Index (£SCI), click here for details.

To ensure you use the genetics best suited to your business, please select from the correct index below to be directed to the relevant bull lists. Further details on each index can be found below via the links below.
