There are currently two different selection indexes calculated for New Zealand Angus animals. These are:

• Self Replacing Index
• AngusPure Index

Each selection index describes a different production/market scenario and relates to a typical commercial herd in New Zealand that is targeting the following specifications.

Self Replacing Index – Estimates the genetic differences between animals in net profitability per cow joined for a self replacing commercial herd, targeting the production of grass finished steers. Steers are assumed marketed at 525 kg live weight (280 kg carcase weight and 10 mm fat depth) at 16 months of age.

AngusPure Index – Estimates the genetic differences between animals in net profitability per cow joined for a self replacing commercial Angus herd, targeting the production of grass finished steers for the AngusPure programme. Steers are assumed marketed at 525 kg live weight (280 kg carcase weight and 10 mm fat depth) at 18 months of age with a significant premium paid for marbling.
