Dairy Breeding and Genetics

Breeding high quality cattle using good genetics is at the heart of profitable dairy farming.

Genetics can help build milk production as well as health and management traits into your herd and any decisions are cumulative, building over the generations.

Improved dairy genetics are estimated to have delivered £32.4 million of benefit across the British herd in 2018.

AHDB are the independent source for genetic evaluations, breeding indices and analysis for all major UK dairy breeds.
