Various aspects of this process of finding selection criteria that are widely accepted and implemented are reviewed and scientific principles can be used to ensure that the outcome best meets both the perceptions and needs of the users while remaining as close as possible to the technical economic optimum.

Using the choice experiment method in the design of breeding goals in dairy sheep.

The purpose of this paper is to present an example of the use of a choice experiment (CE) in the estimation of economic weights for sheep traits for the design of breeding goals and reveal unobserved preference heterogeneity for fertility, adaptability to grazing and resistance to disease.
