Our Story

Over 40 Years of Simmental History

Clay Lassle was a junior in high school when he attended a course on artificial insemination. LRS then started AI’ing and had their first Simmental calves in 1975. His father, Erwin Lassle, had predominately raised Angus cattle, but he offered no objection to Clay’s foray into the continental breed.

“The Angus cattle were small and lacked performance at that time. We thought we’d try to get something with a little more performance,” explains Clay.

LRS is a family run operation just 20 minutes west of Glendive, Montana. Clay & Marianne’s daughter, Sarah and her husband Ryan as well as their two daughters are very involved in the day to day running of the ranch. Stephanie and her husband Scott, as well as Travis and his wife Alix and their children help when needed. They are given a few cattle and a lot of work, which means no other workers are needed. It’s all done by family.

One of the Most Respected Prefixes in the Simmental Breed…

Like the cattle of the commercial producer, LRS cattle are range-grown. That is why LRS bulls are so commercially appealing. They still raise purebred Angus as well as Simmental cattle, and can boast that there is little difference in frame size between the two breeds. Their Simmental/Angus cross cattle are also very popular to the commercial man.

They strive to produce cattle that have balanced EPDs, are functional, solid colored, polled, moderately framed, and can survive the rugged terrain of Eastern Montana as well as anywhere in the country. The extensive use of AI breeding to top sires, ET, carcass data collection, ultrasound and physical measurements all help make the LRS prefix one of the most respected in the Simmental breed.

LRS runs about 250 mother cows, both percentage and purebred Simmentals, and sell 120 – 130 bulls per year.
