Cows

M.R. Angus Ranch was established in 1977 at Tie Siding, WY, by Juan and Joni Reyes. The original cow herd consisted of twelve registered Angus cows with Eileenmere bloodlines. Ranching at 8,000+ feet it was quickly realized that finding a cow herd with the right genetics and conformation was of upmost importance to survive at high altitude. After much consideration, the decision was made to expand by purchasing cows from the Fairview Ranch dispersal sale. Most of which were of Canadian breeding. Today’s herd consists of over 1000 head which can be trace back to those original bloodlines.

Our cow herd has proven year after year that it has maternal longevity and can adapt to tough environments. We continue to strive for quality, performance, conformation, fertility, and easy fleshing abilities that will work at any altitude.

In 2009 we started to transition from calving in January to June with a 45 day breeding season. In 2025 we had approximately 80% of the calves born in the first cycle, same as the year previous. That was ALL NATURAL SERVICE BREEDING, NO AI, NO SYNC. We kick out 4-10 bulls per group depending on size, which means every calf is DNA tested for parentage. Cows go to ranches typically in May depending on weather. Once they are at the summer ranch they calve on their own. The crew tags and weighs calves but as for management that cow is in charge. She better pick that calf up and get him sucking and protected because if she comes home dry she’s down the road.
