Angus GROUP BREEDPLAN uses a multi-trait analysis procedure that takes
into account known genetic and non-genetic relationships (correlations)
between the various birth, growth, carcase and fertility traits. These
correlations have been calculated from the Angus database by researchers
at the Animal Genetics and Breeding Unit, University of New England,
Armidale. In some cases additional research data has been used to estimate
the correlations. These relationships are regularly re-estimated as additional
performance data and research results are obtained.
The following graphs illustrate some of the key genetic correlations
currently built into the Angus GROUP BREEDPLAN analysis. Additional
non-genetic (environmental) correlations are also used to assist
in the calculation
of Estimated Breeding Values for each trait.
