Colyer Hereford & Angus

Location: Bruneau, ID

Breeds: Angus, Hereford

Colyer Herefords & Angus has been one of the West's most respected seedstock operations for over 46 years, running a multi-generation Hereford and Angus program out of Bruneau, Idaho focused on producing functional, high-performing bulls for commercial cow-calf producers. The Colyer family is deeply committed to pigmentation, udder quality, structural soundness, and carcass merit, with an emphasis on the heterosis advantage that Hereford-sired black baldy females deliver on Western rangelands.Their annual production sale offers an extensive lineup of yearling and fall bulls across both breeds, supported by a robust embryo transfer program and Platinum TPR Breeder recognition from the American Hereford Association. Guy Colyer, a fifth-generation rancher, leads a program that regularly competes at the Denver Stock Show and produces breed-leading EPD profiles backed by whole-herd data and genomic testing.
