Our Story
When John Rymer founded JSR Farms in 1958, he established some important business principles. He also set out a simple formula that has continued to provide a focus for the group’s activities and growth - people, pigs, peas and potatoes.
Today, JSR is one of the largest family owned farming companies in the UK.
It has two companies; JSR Genetics - A highly successful international pig genetics company and JSR Farms - an integrated arable business demonstrating sustainable farming.
