WELCOME TO MASON ANGUS & SIMANGUS

Mason Angus and SimAngus, a third generation family owned seed-stock business, is located near Anselmo, Nebraska and is operated by Tim and Kristi Mason. We are committed to providing cattlemen with superior genetics to ensure calving ease, docility, maternal strength, and profitability. Our cattle have flourished in many conditions from the heat of California to the cold of North Dakota and Montana, or one might say, a year in the Sandhills of Nebraska. Our goal is to continue to provide reliable and quality seed-stock for producers to incorporate into their own herd to meet the producer’s needs.

We appreciate your interest in Mason Angus and SimAngus and look forward to the opportunity to work with you. Visitors are welcome at the ranch anytime! Additional information on our Mason Angus and SimAngus Bull and Female Sale can be found by visiting the Annual Sale tab.

Our top selling bull in 2024, we are very excited for the first Mason Landmark calves to sell in 2026! His uncanny number package, outcross pedigree, and dense build made him attractive to breeders around the country. Landmark is a heavy muscled, moderate framed bull that is fault free in his design. Use him to improve data everywhere while adding center and dimension to calves.
