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 contribution of the Topigs Norsvin Z-line ensures high numbers born alive with minimal variation in birth weight, but more importantly from a sow designed to rear these larger litters. Thanks to the recording of growth and carcase traits in the nucleus lines the maternal genetics does not limit finishing performance, and, with selection to reduce prolonged weaning to service intervals in the sow, as well as conformation traits, the longevity ensures the sows have a longer contribution to the herd, helping reduce replacement costs.
