Cooper and Holden Herefords 45th Annual Production Sales

Jay George

Cooper Hereford Ranch and Holden Herefords are two of the American beef industry’s most respected and recognized performance seedstock herds. These Montana-based breeding operations were established in 1947 by performance pioneers Jack Cooper and Les Holden with foundation Line One Advance Domino cattle direct from the Miles City (MT) Range Station. In the past 60 years, these programs have continued to be built upon the principles of production testing and linebreeding with emphasis upon proven, superior cow families.

Founders of the Montana Beef Improvement Association in 1956, the Coopers and Holdens were leaders in the development of beef cattle performance testing with objective selection priorities based upon commercial cattlemen’s economically important growth, maternal and, more recently, carcass traits. These firms have been a leading source of linebred, Line 1 genetics that have impacted the Hereford breed and commercial cowherds across North America and dominated the American Hereford Sire Summary listings from its beginning.

Jack Holden, Valier, MT and Mark Cooper, Willow Creek, MT and their families presented their two-day, back-to-back sales at the respective ranch headquarters to full house crowds of cattlemen from 22 states across American plus Canada. In the long successful history of these two firms, their 2011 sales were record events. Hereford breeders and commercial ranchers, both, sought to invest in the predictable, linebred, balanced traits that are the mark of HH Advance and CL1 Domino bred Herefords – and the powerful, crossbred black baldie heterosis that is delivered by linebred Hereford bulls.



These sales’ results stand as testimony to the genetic power, level of performance, superior quality, integrity and founding principles that have now been the trademarks of Cooper and Holden Herefords for generations.
