About Columbia SheepAbout Columbia Sheep



Columbia sheep were one of the first sheep to originate in the United States. They are the result USDA and university research. Development began in 1912 in Laramie, Wyoming. Lincoln rams were crossed with Rambouillet ewes. In 1918, the foundation flock was moved to the U.S. Sheep Experiment Station near Dubois, Idaho, for further refinement.  

Though originally bred for range conditions, the Columbias have found widespread acceptance throughout the United States and are used increasingly to sire crossbred market lambs. Columbias are one of the larger-sized breeds. Rams weigh between 225 and 300 lbs (100-135 kg) and females weigh between 150 and 225 lbs. (68-102 kg).  

Columbia sheep produce a heavy, medium-wool fleece with good staple length and hardy, fast-growing lambs.
