About us

Cogent offers the strongest, most diversified portfolio of bovine genetics available on the UK's genetics market today.

We combine the best of British genetics developed through our own pioneering UK breeding and testing programme with the very best internationally sourced bulls.

Cogent operates the UK's largest bull stud. Based on the commercial requirements of today's dairy farmer, we have successfully developed a breeding programme founded on production, type, and reliability.

Cogent was the pioneer of sexed semen technology and continues its work today to improve the process, research and development of new technologies, which will aid the modern farming business.


Cogent was founded in 1995. Its origins come from the working farms of His Grace the Duke of Westminster's Eaton Estate in Cheshire. It had become clear that putting more and more animals on a limited amount of agricultural land was no longer sustainable and that UK farming needed a new way to improve productivity and the quality of the national herd.

Today the business has come a long way since its farm beginnings and is now one of the UK's leading suppliers of bovine genetics with a growing global reach- currently providing high-quality British products to some 40 countries worldwide.

Since the acquisition with ST Genetics in October 2017, Cogent have not only increased its global network of bulls by acquiring a new line-up, but also gained skills, expertise and technology, expanding the sorting laboratory in Cheshire to become the largest in Europe. Not only do we offer world class products but also specialise in delivering an excellent service to each and every customer to suit individual needs.

However, despite its ongoing success and international reputation for technological innovation, it remains committed to farmers and works closely in partnership with them to ensure that its high-quality products make an effective contribution to a farm's productivity and profitability regardless of its size or location.
