River Creek Farms - Simmental & SimAngus Bulls We breed Simmental and SimAngus bulls that are built to work. Learn more about us and request a catalog at www.RiverCreekFarms.com

River Creek Farms is a diversified family operation owned and operated by the Mertz families. The family’s interest in cattle began in 1891. The farm headquarters is located approximately nine miles east of Manhattan along K18, in the Kaw Valley River bottom. Our main crops are corn and soybeans, with some wheat and alfalfa on over 3000 acres of leased and owned cropland. Most of this cropland is

in the river valley with some upland ground. We do some irrigation with center pivots and flood irrigation. We graze the cowherd during the summer in the Flint Hills pastures south of the farm. The cowherd grazes the cornstalks in the valley during the fall and winter. We have been breeding Purebred Simmental cattle since the early 1970's. This is also when we became official members of the American Simmental Association. Our breeding philosophy is the same today as it was 30 years ago. We have consistently focused on producing cattle that will excel in any condition, while focusing on the economically relevant traits like Calving Ease, Growth and Carcass Value.

💥💥 RVR TYSON 429K 💥💥

Check out this new mature photo of RVR TYSON 429K. This bull is gaining serious semen sales traction this spring, and for good reason. He’s a six-plus frame, long-bodied powerhouse, with a flawless EPD profile. He’s already been used heavily in several large heifer projects this spring, and demand continues to build with commercial cattlemen across the country.

If you’re looking to sire bigger-framed, growth-driven SimAngus cattle without giving up calving ease or maternal strength, TYSON flat works.

Take one look at the sons in our development pen for the November sale and you’ll see it. Length. Shape. Power. His calves stand out.

And the best part, he’s priced to use at $30 per unit w/ free shipping on every order.
