Abstract
Livestock Improvement Corporation is presently undertaking a major review of genetic and
production evaluations it provides to the New Zealand dairy industry.
The Animal Evaluation Review is investigating the use of a sophisticated method of
producing animal evaluations known as the Animal Model. The review is now looking into
methods of combining the individual trait outputs from the Animal Model into predictors of
animal genetic and productive performance. It intends to provide evaluations across breeds. The purpose of this paper is to look at the possible consequences of evaluating across breeds,
potential effects from appearing to rank one breed above (or below) other breeds, and to
provide some conclusions concerning the breed issue.
The objective of the animal evaluation system is to provide the industry with the tools to
choose the most appropriate animals for production and breeding use. The definition of "most
appropriate" requires definition. The breeding objective proposed for the Animal Evaluation
Review is to "maximise nett farm profit per hectare".
