Spring Calving Index £SCI

£SCI is an across-breed genetic ranking index designed for UK spring block calving herds.

The index is an initial screening tool to identify bulls that meet a specific criteria. 

Use our Herd Genetic Report to identify traits to improve in your herd through breeding.

£SCI value represents the additional profit a high £SCI bull is expected to return from each of its milking daughters over her lifetime compared to an average bull of £0 SCI. 

The index has been calculated on its own base and for a specific farming system; so comparison of bulls on the £PLI or £ACI list is not possible.

Why choose £SCI?

  • Promotes milk quality rather than volume
  • Has a strong emphasis on fertility
  • Selects for reduced maintenance costs
  • Improves udder and leg health
  • Places a strong emphasis on longevity
  • Promotes easier calving
  • Protects functional type - feet & legs and mammary 

Relative weighting of traits within £SCI

Four simple steps when selecting the right bulls for your breeding programme:

  1. Select bulls with a higher £SCI 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
  4. Selected calving ease for maiden heifers
