The NAAB Doak Graduate Fellowship is a unique opportunity for individuals planning to pursue a career in the bovine genetic improvement industry to earn a Master of Science degree in bovine genetics or bovine male reproduction physiology. This is intended for individuals who have long term aspirations in the genetic improvement industry as exemplified by Dr. Gordon Doak, who dedicated 42 years to developing NAAB programs.

CSS and APHIS renewed a Memorandum of Understanding (MOU) effective on April 23, 2020 that extends the unique private-public sector cooperation. This is a mutually beneficial relationship that recognizes the integrity of the CSS programs and demonstrates the close working collaboration with APHIS.

Prior to the April genetic evaluations, model changes were announced for both calving ease and stillbirth. These changes considerably improved the accuracy of the traits and improved the stability of the evaluations. A base change was applied for the calving traits as well; however, while PTAs for most traits decreased due to the base change, PTAs for the calving traits went up.
If we are making slow-but-steady genetic progress, why do you see higher PTAs for calving ease on your favorite bull? In fact, there are probably bulls that you have used frequently with no issues that have high PTAs for Sire Calving Ease (SCE). Why?

The April 2020 sire evaluation had more changes than usual. This is not coincidental. The most noticeable of changes was the genetic base change.
Because the genetic base change affects PTAs already, it’s beneficial to include others changes to models, traits and indices in the same evaluation. That way, the dairy industry isn’t hit with multiple large changes in a row but instead has one large “reset” and can then continue with a stable set of proofs. It can be confusing, however, to understand all the changes and how they affect the PTAs on familiar and new bulls.
This is a summary of all the changes to the genetic evaluation that were implemented in April 2020. While it is impossible to calculate what change caused what PTA to shift, the list below may give you an idea of why a certain PTA on a specific bull changed the way it did.

The National Association of Animal Breeders (NAAB) members report annual units for the categories of domestic sales, export sales, custom collected, imported units for dairy and beef breeds. With 95% of the US AI industry represented by NAAB members, these annual statistics give an unprecedented reflection of US cattle semen sales.
