Signet Recording Scheme
Some of the EBVs are combined into an Index. In the case of Suffolk’s and other terminal sires, the index objective is to select superior animals to increase lean meat yield in the carcase whilst limiting any associated rise in fatness.
The Signet evaluations are analysed by Egenes at SAC and are supported with funding from Eblex, HCC and QMS levy boards.
