Because Great Cows Start with Great Genetics: The 6-X Genetics Advantage

In the ever-evolving world of dairy farming, success hinges on a foundation of great cows-cows that are healthy, productive, fertile, and built to thrive in real-world commercial dairy environments. At 6-X Genetics, we believe that great cows start with great genetics. It’s that simple.

Our mission is to elevate dairy production by empowering farmers with the world’s most reliable and results-driven crossbreeding solution: ProCross. Backed by decades of research and real-farm performance data, 6-X Genetics partners with dairy producers across North America to implement genetics that don’t just perform on paper-but deliver in the parlor, the pen, and the paycheck.

The Science of Strength: What is ProCross?

ProCross is a strategic three-breed crossbreeding program that combines the best of the Holstein, VikingRed (Scandinavian Red), and Montbéliarde breeds. ProCross was originally developed right here in Oakdale, CA through a collaborative effort that included Stephane Fitamant, Bergwerff Dairy, Prins Dairy, Creative Genetics, 6-X, Crane Villa, Hoekstra Dairy, Willie Bylsma, and the University of Minnesota. Developed over 20 years ago and now used on commercial dairies worldwide, ProCross was designed with one goal: to build a better dairy cow-healthier, more fertile, longer-living, and more profitable over her lifetime.

Unlike random crossbreeding, ProCross is a structured rotation of three proven breeds that complement each other genetically. This method captures the power of heterosis (hybrid vigor) while maintaining breed strengths. The result is a more resilient cow with improved performance across all critical traits.

At 6-X Genetics, we make this system accessible and effective for North American dairies-large or small-providing elite sires from each breed, expert genetic consultation, and a long-term vision for herd success.

Proven Performance Backed by Research

The benefits of ProCross aren’t just anecdotal-they’re backed by some of the most robust and peer-reviewed research in the dairy industry. A landmark 10-year study published in the Journal of Dairy Science (January 2021) compared ProCross cows to pure Holsteins across multiple U.S. dairies.

Here’s what they found:

●ProCross cows outperformed pure Holsteins in lifetime profitability by over $500 per cow.
●They produced more energy-corrected milk per day over their lifetime.
●They had significantly higher fertility rates and lower culling rates.
●They displayed greater longevity, averaging over 300 more days in production.

These findings confirm what ProCross users already know: ProCross cows stay in the herd longer, breed back faster, and put more money in your pocket over time.

At 6-X Genetics, we proudly offer the bulls that make these results possible-elite sires from VikingRed, Montbéliarde, and Holstein lines, carefully selected for real-world traits like health, strength, and adaptability.

Why Crossbreed? The Advantages Are Clear

If you’ve relied on pure Holsteins, you know their strengths-but also their challenges: metabolic disorders, fertility problems, and shortened herd life. Crossbreeding isn’t about abandoning
Holsteins-it’s about enhancing their strengths and mitigating their weaknesses.

Here’s how ProCross improves your herd:
●Improved Fertility Fewer services per conception. Shorter calving intervals. Cows that breed back faster and more reliably.
●Greater Health & Longevity Crossbred cows experience fewer cases of mastitis, metritis, ketosis, and other common disorders. They last longer and produce more over time.
●Better Feet & Legs Montbéliarde and VikingRed influence leads to stronger locomotion and fewer hoof issues, making cows better suited to commercial housing and high-production environments.
●Feed Efficiency & Durability ProCross cows convert feed more efficiently into milk. Their medium stature and robust frames are ideal for longevity and sustainability.
●Sustainability for the Future Longer-lasting cows mean fewer replacements, fewer heifer rearing costs, and reduced environmental impact per pound of milk produced.

The 6-X Genetics Difference

What sets 6-X Genetics apart is more than just great bulls-it’s our approach. We don’t just sell semen. We partner with dairy farmers to build better herds.

●Holistic Genetic Strategy: We’ll help you implement and maintain a structured crossbreeding program tailored to your operation’s goals.
●Elite Sires: We provide access to the world’s top-performing ProCross bulls, selected for fertility, health traits, durability, and commercial performance.
●Field-Proven Results: We work with real farms, real herds, and real numbers-not just theoretical indexes.
●Educational Support: Through events, tours, and hands-on consultation, we help dairies understand and embrace the genetic advantage.

Whether you’re looking to stabilize reproductive performance, reduce cull rates, or simply make more money from every cow in the barn, we’re here to help make that happen.

Montbéliarde, VikingRed & Holstein: The Ultimate Trio

The power of ProCross lies in its complementary design. Here’s a closer look at what each breed brings to the table:

●Montbéliarde (France) Known for outstanding strength, fertility, and longevity. Adds durability and improves structure-especially feet and legs. Excellent choice for herds battling lameness or short herd life.
●VikingRed (Scandinavia) Famous for health traits and reproductive efficiency. Boosts calving ease, mastitis resistance, and metabolic stability. VikingRed cows are low-maintenance and thrive
under commercial conditions.
●Holstein The global leader in milk production. ProCross uses only top Holstein bulls selected for
ECM and udders, ensuring balance and consistency in the rotation.

When rotated correctly, these three breeds produce a hybrid cow with optimized performance,
improved welfare, and better lifetime return.

Join the ProCross Movement

Across the U.S. and beyond, thousands of commercial dairies are discovering the value of structured crossbreeding-and 6-X Genetics is proud to lead the charge.From progressive herds in California and the Midwest to new adopters looking for sustainable solutions, more producers are seeing firsthand the benefits of ProCross: cows that are built to last, breed, produce, and thrive.

We’ve seen customers increase profitability, decrease involuntary culling, and improve milk quality and components-all while simplifying their breeding strategy.
