Sire lines

JSR sire lines are world-renowned, offering great performance, efficiency and consistency to pig producers. Our commitment to improving meat quality ensures that we are producing pigs that truly are fit for farm and fit for fork.

Geneconverter 400

The JSR Geneconverter 400 is a Hampshire based sire line sourced from stock raised without the use of antibiotic growth promoters since 1986. The result is an animal which breeds progeny with low levels of mortality due to improved levels of immunity and high feed intake, leading to good growth rates.

Geneconverter 900

The JSR Geneconverter 900 delivers the most impressive performance results we have ever seen against all our competitors, growing 60-110g/day faster from weaning to slaughter in independent trials, and is the most cost effective terminal sire available to UK producers, being up to three weeks quicker to slaughter.
