To help you breed the right cow to fit your system AHDB Dairy recommend the following four step plan when selecting bulls for your breeding programme:
  1. Select £PLI bulls with a higher value than your best cow
  2. Select fitness traits to maintain your strengths and address herd weaknesses (Fertility, Lifespan etc.)
  3. Match type to suit your herd
The main updates introduced in 2018 are shown below:

Relative weighting of traits within £PLI

The £PLI:

  • Promotes yield and maintains milk quality
  • Increases emphasis on fertility
  • Improves functional type – feet & legs and mammary
  • Increases emphasis on longevity
  • Reduces maintenance costs
  • Improves udder health
