  WELCOME


We are located in northeastern South Dakota between the James River Valley and the Coteau Hills.  Our annual rainfall is 17 inches and the temperature varies from over 100 degrees to 40 degrees below zero blended with snow and wind.  Our cattle must not only tolerate the weather extremes of the Northern Plains- they must thrive; and they must do it without pampering.  Our pastures are native grasses on land either too hilly, too rocky, or too wet too farm.  We feed native grass hay, alfalfa hay and wet distillers byproducts during non grazing months.

We place our highest genetic emphasis on moderation in size, quiet disposition, fertility, longevity, and carcass.  We select for long cows that breed up quickly and calve easily and bring a good calf home in the fall.  Our cattle are selected to be trouble free converters of roughage and efficient producers of desirable beef.

 We are believers in the highest level of livestock health and adhere strictly to a

bio-security protocol to protect our herd and our customers.  We employ the BQA recommended techniques and utilize Pfizer (now Zoetis) products including modified live vaccines and Dectomax wormers.  We have utilized the Select Vac program outlining the

preparation we have invested in our cattle.  Along with Bangs vaccination our heifers during the pre weaning vaccinations, we have utilized EID tags to for additional identity

confirmation along with numerical freeze branding.  

 We have voluntarily participated in the South Dakota Johnnes program since 2006.  Eventually the program got more and more complicated and we now blood test every pregnant cow over 36 months of age, every year.  We also ear notch every bull in our sale for persistent BVD.  These efforts give our customers the confidence that they are buying and bring home clean animals that have never been exposed to a sale barn.  Our bulls are all put thru a breeding soundness exam administered by Clark Veterinary Service of Clark and upon satisfactorily passing given the “bull package” vaccinations which include a killed viral booster, pink eye and foot rot.  We then give the bulls one more foot rot booster…we treat the bulls we sell exactly the same as the bulls we keep or buy for our own use….its just the right thing to do.
