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 programs 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 is ‘powered by Topigs Norsvin’, meaning UK customers benefit from the larger datasets, breeding value calculations and technology from the combined businesses. As a result of this genetic agreement, we look forward to offering our UK customers the very best parents available globally.
The JSR 15T is a naturally progressive outdoor female and is the product of Topigs Norsvin’s genetics and JSR’s developments. The 15T is a robust and strong sow, which allows outdoor producers to compete with the prolificacy of higher management input production systems without increased sow mortality in the outdoor conditions
The JSR 9T is the first product created from the innovative genetic partnership between JSR Genetics and Topigs Norsvin. The JSR 9T is a hybrid dam line combining the Topigs Large White Z Line and the JSR Landrace. It is a prolific female with exceptional weaning abilities and an outstanding and unique contribution to finishing performance.
The 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 line. 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 150 allows outdoor producers to achieve year round output in excess of 13 pigs born alive without detrimental impacts on the sow and piglet mortality during the lactation period. The inclusion of a 50% White Duroc rather than the traditional 50% Red Duroc or lowering Duroc inclusion means that outdoor producers are not restricted in their choice of terminal sire line and can use the most profitable coloured terminal sires available in the market without impacting on value of the slaughter progeny.
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.
Compared to our leading competitor, the JSR Genepacker 90 produces an extra 4.6 pigs born alive per sow per year, representing a valuable boost to your productivity and profitability. This is combined with up to 29% more sows surviving to parity 4 and 33% more sows surviving to parity 6, as demonstrated in independent trials compared to competitors' parent sows. The resulting lifetime profitability means the JSR Genepacker 90 is a prudent choice for pig production businesses planning a financially sustainable future.
