Recumbency in Holstein Calves

Researchers at Penn State University have been collaborating with colleagues at USDA's Agricultural Research Service to study a new genetic defect in Holstein cattle. This defect is characterized by otherwise healthy animals that are unable to stand.

This condition, currently called calf recumbency, has proven to be more complex than other known genetic defects. Considering the animal welfare aspect of this defect, the development of a reliable diagnostic tool is very important to consumers, farmers and the dairy genetics industry.

The industry position
The industry acknowledges that this defect must be addressed quickly. The priority is to provide access to accurate diagnostic tools with transparent and wide communication of carrier statuses of affected males and females. 

Commercial gene tests are currently available and the AI Total bulls are actively being tested. At this time, you will not see an indication of carriers or non-carriers in the sire directory or website. Once the industry has a plan to display this information, we will share that with you. We want to be transparent with our clients and provide what information we have with you, so that you can make the best decisions for your herd. Below you will find the most current results. Please check back regularly as this list will be updated frequently.
