April 2020 Genetic Base Change

March 3, 2020

The US genetic evaluation system will have a genetic base change in April 2020. This is in accordance with global standards set by the International Committee for Animal Recording (ICAR). This ensures that everyone evaluates the genetics of their animals to an up-to-date average population. Every base change brings a considerable shift in PTAs even though the genetics of our breeding stock obviously don’t change overnight. The more genetic progress we make, the bigger the base changes are.

Why do we do this, what does it mean exactly and what will be the changes in April?

Is our U.S. A.I. industry OK?

January 2, 2020

It’s been nearly 75 years since the introduction of frozen semen for artificial insemination (A.I.) and 10 years since genomic selection. During those years, the U.S. has catapulted itself to the position of world leader in bovine genetics, which is a comfortable position to be in.

Semen sales are increasing each year; yet, if you’d ask anyone related to the industry how our business is doing (producer, scientist, A.I. rep, classifier, breeder), you are likely going to get a mixture of reactions. You may get anything from “on the verge of collapse” to “better than ever.”

The industry seems to be stirring, and it feels uncomfortable. Is our A.I. industry OK?
