April 2019 – Holstein Canada Genetic Evaluations

For the April 2019 – Holstein Canada Genetic Evaluations, an updated Holstein Pro$ and LPI formula come into effect. The genetic base for Pro$ was also updated so that the units and scale of expression remain correct over time. This means that there will be an observed average Pro$ decrease of $420 for the top proven Holstein sires due to the genetic base update. Since this is the first genetic base update for Pro$ since it was introduced in 2015, this translates to an annual genetic base of $105 per year. Going forward, at the time of the April evaluation each year, CDN will automatically update the Pro$ formula and apply a genetic base update similar to the process for production traits. See the Summary Table for the April Evaluation HERE!
