US Holstein

Product benefits

For decades, North America has been a major supplier of genetics. CRV has a very successful breeding program in the USA. As a result, the best American bulls with the highest breeding values are available for our clients.

In the USA, CRV is looking for bulls and bull dams that are interesting for North America as well as the international market.

To compare these bulls with the bulls of the Delta and Eurodonor breeding program, the American bulls are also tested on NVI base, next to their US TPI base.

On top of the 60 bulls that are tested in Europe, CRV is also selecting about 18 bulls per year in the USA. CRV selects all bulls based on high components, excellent health and good efficiency.


Proofs from around the world

In addition to the official US proofs such as $NM, CRV publishes an additional package of proprietary CRV traits of all US Holstein bulls.

This allows our customers to breed for traits such as Milk Urea Nitrogen, casein in milk, milking speed but also fertility corrected for sync protocols.


Better Life Figures

To support farmers in selecting the specific bulls they want, we have developed the Better Life Figures. These figures are proprietary to CRV and provide the most accurate way of breeding for health and efficiency.

Selecting the highest ‘Better Life Health’ bulls will lead to easier to manage (healthier) cows and selecting the highest ‘Better Life Efficiency’ bulls will lead to higher lifetime production with lower feed intake.

Our Better Life figures are published for all our US Holstein bulls.
