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.
