Trait economic weights for genetic improvement with SIL

Trait economic weights for genetic improvement with SIL

Proceedings of the New Zealand Society of Animal Production 60: 189-191

This paper outlines the construction of industry selection indexes for the SIL sheep genetic evaluation process. Traits of direct economic importance in New Zealand sheep production form goal trait groups with each goal trait assigned an economic weight for use in selection indexes. Goal trait group indexes are calculated as the sum of breeding values for each goal trait within the relevant group after multiplication by the relevant economic weight.
