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.
