Our Hereford cattle all descend from a closed line of breeding (Line 1) that trace back to genetics used in a line-breeding research project from the early 1930s conducted at the USDA Research Station in Miles City, MT. Our family has continued this closed line of breeding for over 80 years now and there’s no denying the balance, predictability and consistency it’s brought to our herd. Our Line 1 genetics offer a unique degree of heterosis that both registered and commercial breeders alike are seeing the benefits from.

Rooted in performance, focused on maternal. We’ve stacked generation after generation of performance testing on top of selection for maternal traits. Couple that with a committed approach to linebreeding, which has elevated the uniformity and predictability in our herd while also guaranteeing a high degree of transfer to offspring. Whether you’re breeding to Herefords or implementing cross breeding, our Line 1 program ensures a unique opportunity to maximize heterosis.

The Line 1 project in Miles City focused on establishing methods of measuring performance in beef cattle and attempting to prove that traits such as weaning and yearling growth were inheritable and could be improved through genetic selection. Most people might not realize it, but the results of that project laid the framework for performance testing and the genetic evaluations for all breeds today. Patriarch, Jack Cooper, bought into this concept, purchased his first L1 registered females from the station in 1947 and started performance testing long before it was accepted by most cattlemen or Breed Associations. Jack Cooper was a charter member of the Montana Beef Performance Association and a charter member of the American Hereford Association Total Performance Records. Our ranch has been utilizing data collection and performance testing for over 70 years and was one of the first ranches in the Nation to do so.

The platinum whole herd total performance records (TPR) is the highest level of achievement when it comes to complete calf crop reporting. Breeders must meet ALL the requirements of a gold TPR breeder status (listed below) plus genotype 85% of their calves with a submitted weaning weight. Only 1% of Hereford breeders registered with AHA meet the qualifications for platinum TPR status and Cooper Hereford Ranch is one of them.

• Complete reporting of calving ease and reproductive status for each dam on inventory.

• Complete reporting of birth weights, weaning weights and yearling weights for each live calf recorded in the calf crop.

• Complete reporting of weaning weights for each live calf recorded in calf crop.

• Complete report of scrotal measurement for each bull calf in the calf crop with a recorded yearling weight.

• Ultrasound data reported on 25% or more of the calf crop.

No. pairs are turned out to pasture in mid May and primarily graze irrigated grass/legume pastures until they are weaned in late August. Groups are supplemented with loose mineral and salt.

Bull calves are weaned the day after Labor Day, placed in a drylot and fed twice daily a mixture of chopped hay, corn silage, whole corn and a mineral based protein supplement. Most of the bulls exceed our target gain of 3.5 lbs./day, which we feel is adequate to ensure they have enough flesh to maintain condition as a yearling without sacrificing structural integrity.

All sale animals have been tested and are free of any known genetic defects. Additionally, all bulls and heifers have been ear notched and are negative for PI and BVD. Montana is once again Class Free with regard to brucellosis - all sale animals have been bled and tested negative.

Yes. All animals listed in the catalog have GE-EPDs. The American Hereford Association released its first GE-EPD panel in 2012. That year we were one of the first herds in the U.S. to test our entire cow herd and that year’s calf crop for evaluation. We have continued to submit DNA on each subsequent calf crop since inception in 2012.

Yes, all bulls selling through the auction have passed a BSE completed in January by Dr. Will Oliver, DVM. Scrotal and pelvic measurements are obtained by Dr. Oliver as well.

Our bulls are not PAP tested but many have sold to ranchers running at high elevation and have performed well and have also passed testing once on site.

No. We love a packed sale barn, and always invite and encourage attendance so you can see the cattle firsthand. But understand that for many of you, March is a difficult month to step away from your operation. So online bidding is available through LiveAuctions.TV and Northern Livestock Video Auction. Those who have unreliable wi-fi can contact one of our sale day representatives in advance, or take advantage of Northern Livestock’s phone bank for assistance during the auction.

Yes. We offer free delivery for the first 1,000 miles on purchases totaling $5,000 or more. Deliveries are to central points.

No, but insurance providers are listed in our catalog for those interested. All animals sold become the property of the purchaser as soon as sold. Any death or injury thereafter falls upon the purchaser.
