Spring Calving Index - £SCI

A new economic breeding index for spring block-calving systems

The Spring Calving Index (£SCI) is an across-breed genetic ranking index developed in consultation with industry partners specifically for spring block-calving herds and expressed as a financial value.

Profitable Lifetime Index - £PLI

An economic breeding index for UK autumn block and all year round calving herds

The national Profitable Lifetime Index (£PLI) is published by DairyCo Breeding+ as part of its genetic evaluation service. The £PLI is a within-breed genetic ranking index developed for UK dairying conditions in consultation with industry partners and is expressed as a financial value.

Farmers Wish List

Lifespan is a recurring theme in the ‘Farmer Wish List’. When you use PLI as a selection criteria, 14.4% of the calculation is based on longevity. By selecting bulls with a higher PLI you reduce the risk of a poor longevity score.

Alongside lifespan, daughter fertility and geting cows back in calve quickly and easily is also high on a farmer’s wish list, with fertility making up 20.3% of the PLI calculation.

Select your individual criteria traits to be able to compare bull figures. Use PLI as a base selection criteria and then select your bulls from the top 100. Elite high genomic bulls will oen be in short supply, which will be reflected in a higher straw price. Look at the bulls that meet your selection criteria, but also represent value for money.
