Collecting Performance Data

Canadian Angus Association members and their commercial customers, in our 2019 survey, identified traits that were important to them in their own operations.

We currently do not have genetic evaluations for these traits. It is evident that our genetic evaluations have to evolve to include traits that are important to our members and their customers. In order to generate EPDs for these traits, we need to collect data on these traits. Herds that collect and submit data on these traits will receive EPDs for these traits.

New traits include high immune response, mature cow weight, height, and body condition score, claw set score and foot angle score, and teat and udder score, residual average daily gain, and docility.
