JSR dam lines are known for their excellent reproductive performance and strong mothering abilities. With an animal to suit your production system, whether indoor or outdoor, all producers can take advantage of the benefits of our genetics.

In May 2015, JSR Genetics and Topigs Norsvin reached an agreement to form a genetic partnership in the UK. This means both companies will combine their Research and Development programmes to achieve faster genetic progress. JSR Genetics will become the exclusive distributor of Topigs Norsvin genetics in the UK.

The sow line breeding of JSR will now be 'powered by Topigs Norsvin', which means Topigs Norsvin will be responsible for breeding value calculations and other technology related to the JSR breeding programme.

As a result of this genetic agreement, JSR Genetics will be able to offer an improved GP90 to the market. We look forward to offering our UK clients the very best of both companies' extensive portfolios.


The JSR 9T is the first product created from the innovative new genetic partnership between JSR Genetics and Topigs Norsvin. The JSR 9T is a white F1 female to maximise heterosis, designed for modern indoor pig production.


The JSR Genepacker 150 is our white but robust outdoor F1 parent produced from a first generation cross between our JSR Genepacker 2 (Landrace) and White Duroc dam lines. This White Duroc parent continues to perform in the harshest of environments thanks to the combination of prolificacy and robustness provided from two dam lines.


The JSR Genepacker 90 is our most prolific F1 indoor gilt produced from a first generation cross between our JSR Genepacker 1 (Large White) and JSR Genepacker 2 (Landrace) dam lines. This parent has an outstanding reputation compared to the competition for prolificacy, longevity and lower input requirements thanks to a smaller mature size.
