How to select your mating sires

When selecting bulls to use on your herd we recommend using only those with a £PLI, £SCI or £ACI greater than the below figures:

Index Breed Minimum for top 50%
£PLI Holstein 446

Ayrshire 173
Jersey 222
Guernsey 0
Shorthorn 0
Montbeliarde 115
Fleckvieh 100

This table will be updated following each full UK genetic and genomic evaluation run in April, August and December.  Current figures are calculated from August 2020 young genomic and daughter proven lists available from AHDB Dairy.
