Percentile Bands Tables

Percentile bands tables provide a useful benchmarking resource for indexes and breeding values for connected flocks within the New Zealand Genetic Evaluation (NZGE). Each month, the percentile bands tables are produced from the most recent NZGE run for Maternal and Terminal traits.

From October 2025, a single set of percentile bands tables is available. This replaces the previous publication of two separate tables for young rams and sires. The change follows discussions with our Sheep Genetics Advisory Group (SGAG) and a thorough review of practices in other genetic evaluations.

By publishing a single set of Percentile Bands tables, we ensure that animals are assessed on a consistent scale over time, making it easier for breeders and farmers to track genetic merit and make informed decisions with confidence.
