Breed Improvement

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.

The Performance 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)

Benefits of the Performance Program include:

  1. Participating members receive adjusted birth, weaning and yearling weight reports that ratio and rank their cattle for in-herd selection
  2. Reduced fees for both registrations and transfers
  3. EPD reports and performance reports generated after data submitted (if herd is compliant)

Performance Program Requirements:

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.

Measuring and Recording Traits:

We record pedigree, performance, and genomic information for use in our genetic evaluations. Performance on traits recorded through the Performance Program include maternal traits, growth traits, and carcass quality traits. For detailed instructions on how and when to measure each trait please refer to the data collection guide.
