Herd Sires


Sale Info.







We Guarantee what others Promise.

One Year Unconditional Guarantee

All bulls sold have an unconditional one year guarantee. If anything should happen to one of these bulls within the next 12 months (365 days) after the sale,  you will get your entire purchase price back on another bull and if something should happen to any of your bulls and he is not able to work, we will loan you a bull to complete your breeding season.

Fertility and Soundness

All bulls are fertility tested, scrotal and pelvic measured and checked in every way for soundness by our veterinarian Dr. Clint Pederson.

Herd Health

All bulls have had vigorous vaccination programs using the most comprehensive and effective vaccines available.

BVD is one of the most common and serious diseases
encountered by cattlemen today.
Introducing untested and non-vaccinated bulls could endanger your entire herd.
The Mangen Angus Ranch continually strives for the best herd health program
possible---to protect your herd from disease while producing the best
calves on the market. The Mangen bull you purchase will be free of
BVD and protected with a new, highly effective type 1 and
type 2 BVD fetal protection vaccine.
We serve the best cattle ranches in the world, and we think
they deserve the best.
