The Inventor and Leader in Balanced Breeding

An integral part

Topigs Norsvin is the originator of Balanced Breeding, a philosophy that has guided our genetic program for more than three decades.

Balanced Breeding combines economic progress with biological balance and long-term sustainability across the pork value chain. Rather than focusing on single traits, it integrates production efficiency, robustness, welfare, meat quality, behavior, and environmental impact into one coherent breeding strategy.

This approach delivers:

Lower piglet mortality and improved survival
Robust pigs suited for group housing and evolving welfare systems
Optimized feed efficiency without compromising meat quality
High carcass value and processing yield
Long-term genetic diversity and sustainable progress

With genomic selection accelerating genetic gain, Balanced Breeding ensures that progress remains sustainable, measurable, and regulated over time.

Balanced Breeding is an integral part of our program; implemented, measured, and continuously refined to deliver value across the chain.

Selecting with a full view

Seeing the Moose Behind the Trees

Imagine driving a high-performance car. The engine is powerful, acceleration is increasing, and you are covering more distance than ever before. But speed alone is not enough. You also need foresight, the ability to anticipate what lies ahead, even what is partially hidden.

Would you want to spot the moose in time to react?

With genomic selection, the speed of genetic progress has increased significantly. As progress accelerates, the need to understand biological interactions becomes more critical. Selecting for one trait affects others, whether we are aware of the connection or not. Biological systems are interconnected and require careful monitoring.

In Practice: Born Equals Weaned

How Balanced Breeding translates into measurable improvements in maternal performance.

Norsvin Landrace

A clear example of the Balanced Breeding approach can be seen in the Norsvin Landrace dam line, where the principle is: every piglet born should be weaned by its own mother.

When data from the Landrace breeding program showed an unfavorable trend in piglet mortality between 2003 and 2008, the breeding goal was adjusted, and survival was explicitly included as a selection trait.

For Topigs Norsvin, litter size is only one part of the equation. It must be matched by teat capacity, piglet vitality, and survival to create real value in practice.

The results in Norsvin Landrace:

Total piglet mortality (stillborn + pre-weaning) decreased by 40% over the past 15 years.
The proportion of litters exceeding teat capacity* decreased by two thirds over the past decade.

*Litters exceeding teat capacity is defined as a litter where the number of liveborn piglets exceeds the number of functional teats.

A Long-Term Breeding Philosophy

Balanced Breeding is the foundation of our breeding program and has guided genetic progress for more than three decades.

Its principle is clear: genetic progress must go hand in hand with biological balance. Focusing on only a few traits may deliver short-term gains, but often creates unfavorable trade-offs.

Balanced Breeding therefore combines progress across a broad range of traits, including:

Production efficiency
Robustness and disease resilience
Behavior and social interaction
Structural soundness
Meat and carcass quality
Genetic diversity for future generations

This science-driven approach enables consistent and responsible genetic progress while supporting the long-term sustainability of pork production.

Translating Genetics into Measurable Value

Balanced Breeding connects genetic progress to measurable impact across the production chain.

On farm, this means improved feed efficiency, reduced mortality, structural integrity, lower labor input, and increased disease resilience.

At slaughter, it contributes to uniform carcass composition, optimized lean meat, improved fat quality, and higher processing yield.

For society, it supports reduced environmental impact, lower antibiotic dependency, alignment with welfare expectations, and preservation of genetic diversity.

By balancing efficiency, product quality, robustness, and sustainability, Balanced Breeding creates value throughout the chain.

Built for Future Production Systems

Pork production is evolving toward larger group systems, reduced antibiotic use, and higher regulatory and societal expectations. Genetics must perform reliably under these conditions.

Balanced Breeding addresses this through selection for robustness, health, behavior, and structural soundness. It combines direct selection, indicator traits, genomics, and large-scale phenotyping to convert biological complexity into measurable genetic progress.

This creates a genetic foundation for consistent performance in modern production systems while actively managing the biological trade-offs that come with long-term genetic improvement.
