Clay Lassle was just a junior in high school when he attended a course on artificial insemination. His father, Erwin, had predominately raised Angus cattle. “The Angus cattle were small and lacked performance at the time. We decided to try to add some performance and Simmental seemed like the right fit,” explains Clay. The first Simmental influenced calves were born on the ranch in 1975.


LRS believes in the power of the data and information. Through the American Simmental Association’s Cow Herd Roundup, they have focused on collecting DNA on every calf born at the ranch. Each year they enroll one of their young herdsires in the ASA’s Carcass Merit Program and in 2021 took it to the next level by making the decision to retain ownership on their steers to give their customers ever more confidence in how their cattle will perform on the rail. This coupled with their extensive use of A.I. and embryo transfer along with their commitment to taking and reporting accurate physical measurements to the breed association all help make LRS one of the most respected in the Simmental breed. When their customers purchase a bull, they can be assured that they are getting what they expect, but if they ever have a problem they will be backed by a 100% satisfaction guarantee.

LRS runs about 350 mother cows, both percentage and purebred Simmentals,
and sell 120 – 130 bulls per year.
