Performance Program

Participating in the Performance Program 

The Performance Program is a voluntary evaluation program designed to help breeders select animals that will propel them toward their breeding goals. The program is based on performance data submitted by breeders and genetic selection tools generated by the Canadian Angus Association.

The most powerful breeding tools used to evaluate cattle herds are Expected Progeny Differences (EPDs). EPDs are values that predict how the future progeny of an animal will perform relative to the progeny of other animals in the breed. EPDs allow for a fair comparison of animals in different herds, and even in different countries.

The Canadian Angus Association evaluates Black and Red Angus animals together in the AngusONE Genetic Evaluation. It is the single evaluation for all Canadian Angus animals which means that Canadian Black and Red Angus EPDs are directly comparable. AngusONE EPDs are also directly comparable to EPDs for Black Angus animals in the USA. Angus Genetics Inc. calculates EPDs for Canadian Angus animals monthly and includes genomic data for members who utilize Angus GS testing.


This program is based on whole herd reporting. This means every cow in the herd inventory must have either a calf or an action code reported. Members are required to complete their cow inventory, birth and weaning weight information every season.

While submitting yearling weights and ultrasound scanning data is optional, we encourage members to do so as it provides data to strengthen their EPDS.

All EPDs have a percentile ranking to summarize where in the breed the animal ranks.

The information provided through whole herd reporting contributes to:

  • Growth EPDs (Birth, Weaning & Yearling Weight)
  • Fertility Trait EPDs (Calving ease Direct and Maternal, Heifer Pregnancy, Stayability, Milk, Scrotal Circumference EPDS)
  • Carcass Trait EPDs (Rib Eye Area, Fat, Marbling, Carcass, Yield Grade EPDS)

Data Collection Guide

Benefits of the Performance Program include:

  1. Worksheets provided after herd inventory updated, birth, weaning and yearling weights submitted
  2. Reduced fees for both registrations and transfers
  3. EPD reports and performance reports generated after data submitted (if herd is compliant)
  4. Provides tools to manage herd more effectively

Any Performance Program members who do not submit all of their information will receive a request to submit missing information. If missing information is not submitted, non-compliance can result in suspension from the Performance Program and a reinstatement fee will apply.

Any performance data that is not submitted on Canadian Angus Association-generated worksheets will no longer be accepted by the Association. Data that is not submitted on proper worksheets is of limited value because there is often pertinent information missing resulting in processing delays and increased staff time to request missing information.
