Spring Calving Sires

Spring Calving Index (£SCI) - This category contains all sires across-breeds that are higher than £300 for SCI


The £SCI was introduced in August 2014 and has been . It provides UK farmers operating a spring block calving system, making extensive use of grass and targeting production of around 6,000 kgs/yr, with an across-breed evaluation to highlight bulls suitable for their system. 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.

The index has been developed to provide an initial screen tool to ensure bulls used on farm meet specific criteria. It is then recommended specific emphasis is placed on the management traits that require attention on individual farms*. The main updates introduced in 2018 are shown below.
