NZGE is New Zealands national across flock and breed evaluation to identify the best rams for economic traits. The NZGE analysis includes all SIL performance-recording flocks, but flocks also have to satisfy specific criteria for NZGE Leader List reporting purposes. These include having good genetic connections with other flocks. Rams from other flocks are listed if they have been used in connected flocks with sufficient progeny evaluated.
NZGE evaluations are made possible by genetic links between breeds: generated by breeders and the B+LNZ Genetics Central Progeny Test.
The following files can be downloaded as SIL formatted reports (pdf) or as comma delimited text files (csv) by clicking on the links below.
NZGE Analysis Information
Values displayed on nprove.nz and in the below tables are currently informed by the NZGEv5 analysis. More detail about NZGEv5 is available here.
Participants and flock connectedness table
This table lists flock type e.g. DP or TS

NZGEv6
From early April 2025 nprove.nz will be informed by the NZGEv6 analysis. NZGEv6 incorporates genotypes from both Terminal and Maternal breeds in one evaluation, increasing the accuracy of BVs and Indexes. The below percentile band tables are informed by NZGEv6 values.

NZGEv6 Sire Percentile Bands Table
NZGEv6 values are currently available from SIL and nProve Breeder and will inform nprove.nz from early April 2025. More detail about NZGEv6 is available here.
NZGE Sire Leader Lists
Leader Lists are no longer being published on this website. Customised Leader Lists can be created at nProve.nz by searching for animals that meet the desired Index, BV and animal criteria.
