Why Jersey on Holstein?

• Reduction in Mature Size

• Improved Components

• Improved Reproduction

• Improved Calving Ability

• Improved Feed Efficiency

• Improved Productive Life

• A Large Genetic Base

In a study conducted by Select Sires comparing the published PTA values for the top-20 Select Sires Jersey bulls to the top-20 Viking Red bulls, the Jersey bulls averaged 149 higher CM$ than the Viking Red bulls. In addition, Jerseys have $109 higher value in the production traits coming from their advantage in fat production as well as their advantage in producing milk with higher component percents. The Viking Red bulls are higher for DPR, livability and have an advantage in somatic cell score. But, these are outweighed by Jerseys being much higher for overall Productive Life. The study clearly shows that Jersey bulls are a profitable option in a three-breed rotational crossbreeding system.

“Use of the best genetics available from each breed in the crossbreeding rotation is critical to success.”

Why Montbeliarde sires on the Holstein-Jersey crossbreds?

• Maintain Moderate Mature Stature

• Improved Reproduction

• Improved Body Condition

• Improved Feet and Legs

• Improved Mastitis Resistance

• Improved Productive Life

• Increased Pounds of Fat and Protein

• Increased Value of Dairy-beef Calves

• A Large Genetic Base

The SelectCROSS approach starts by using elite Jersey sires on purebred Holstein cows. The next step is to use elite Montbeliarde sires on the Jersey x Holstein cross offspring. Pictured are three-way-SelectCROSSes at New Heights Dairy ( daughters of 217MO01016 I TEMPLE JB).

“A good Holstein base, made by selecting high-quality Holstein genetics, is critical for crossbreeding success. When choosing Holstein sires, I choose the very best. You also have to use the best genetics available from each breed in the crossbreeding rotation after that. My favorite cross is the Holstein x Jersey x Montbeliarde three-way. This cross combines the high production of Holsteins, the high components and reproduction advantages of the Jersey breed and the reproduction of Montbeliardes. Purebred Montbeliardes can’t compete on their own from a production standpoint, but when you put the three together you get a well-rounded animal. We measure dollars of product produced per day, and the crossbreds consistently have the advantage.”
