Pontypool-based cattle-breeding company World Wide Sires UK offers British farmers the world's best available proven genetics. Our sires are sourced from the worlds' most advanced and respected genetic evaluation programme through California-based, World Wide Sires Inc.

Our reputation is built on the solid foundations laid down by Ohio-based Select Sires and Accelerated Genetics, Wisconsin. Over the years, many of the Holstein-breeds greatest sires have been developed and proven through the respective progeny testing programmes run by these farmer-owned co-operatives.

The World Wide Sires stud continues to dominate international sire of sons testing programmes. Sons of BW Marshall, Emerson, Elton, Emory, Durham and Blitz, increasingly appear at the forefront of national, international and herd-breeder programmes. Proof, enough, that our selections are recognised as being the best in the world.

World Wide Sires is globally-recognised as the world's premier source of proven bovine genetics. Our reputation is based upon global trust, breeder acceptance and world-wide credibility. We will continue to provide and test the best genetic sires available in order to improve herd-health, longevity and profitability.
