Breeding Blocks

Taking control of your breeding decisions is vitally important if you want to take full advantage of your farming system and milk contract.

The first and vital step is to understand the current status of your herd. Here you'll find the tools, resources and case studies from other farmers to start your breeding journey.

We'll help you select the right sires to meet your breeding goals and shape your future.

Herd Genetic Report

Our report enables you to see the genetic potential of your herd by providing the following information for the cows registered on your farm:

  • Milk (kg)
  • Fat and Protein (kg and %)
  • £PLI, £SCI or £ACI
  • Inbreeding level
  • Management traits - lifespan, SCC, fertility, mastitis and maintenance. Calf survival and lameness advantage are available in the Individual Reports.

The Spring Calving Index (£SCI) is an across-breed genetic ranking index designed for UK spring block calving herds. Find out what £SCI is, how it is calculated, when to use it and the weighting between a range of production and health traits.

1 January 2001

The Autumn Calving Index (£ACI) is an across-breed genetic ranking index for autumn block calving herds. Find out about the reasons for creating a specific index for autumn block calving herds, the components of the index and when to use it.
