AHDB (Dairy) provide the UK dairy genetic and genomic evaluations and host a web page dedicated to Jersey genetics. The dedicated page lists young genomic and daughter proven bulls available to the UK market to identify bulls you might like to use on your herd. All traits evaluated by AHDB are shown in these lists to ensure you are not breeding unfavourable genetics into your herd by checking the sire’s proof through AHDB before purchasing.
To see your own herd genetics and where you rank compared to other Jersey herds in the UK, you can fill in this form to access your Herd Genetic Report (you will need to be full milk recording).

Finally, for more background information on what goes into the various genetic indexes and how to use them the AHDB have put a number of short tutorial videos together which you can find here or you can read their Breeding Briefs guide here.
