CRV Genomic Evaluation

gNZMl, gBW are quoted for bulls whose breeding values are calculated using CRV Ambreed genomic evaluation systems combining parentage, progeny, genomic and Interbull information.

gNZMI uses the same weightings for the traits that are used for NZMI. gBW uses the same Economic Values for traits as BW.

Based on the latest data, genomic biases have been adjusted for, but additional, non-quantifiable biases are present that make direct comparison With BW or LIC's gBW estimates invalid.

Within Breed breeding values

'Within Breed' breeding values are presented relative to a breed specific base animal. The base animal is the average of bulls born 1996-2005 inclusive. All breeding values have been recalculated against this new base with the exception of calving difficulty and the Breeding Worth. Calving difficulty and Breeding Worth are presented on an across breed scale.
