It is now a standard feature on any bull evaluation page: the genotype for beta casein, better known as A2. Despite not being a trait, nor a genetic defect, the A2A2 genotype has grown to become an undeniable marketing tool.

Determining the effectiveness of genetic evaluations for stillbirth in additional U.S. dairy breeds was the research focus for Council on Dairy Cattle Breeding (CDCB) intern Anil Sigdel in summer 2021.

One current discussion suffering from disconnect is the growing use of beef bulls on dairy cows. The beef x dairy practice is a frequently addressed topic, but in many cases the information presented, while potentially important and insightful, is conveyed from a single perspective.

The national genetic index, Net Merit, was updated with the genetic evaluations on Aug. 10, 2021 – delivering an improved tool to breed profitable and feed-efficient cows.

Inbreeding in dairy cattle remains a struggle for the dairy industry, and with the intensive use of genomics; inbreeding is growing faster than ever in many breeds. Increases in inbreeding lowers production and has a detrimental effect by increasing stillbirths, reducing cow fertility, reducing disease resistance, and shortening herd life.
