Horse breeding in Utah, with some exceptions, has been carried on in a hap-hazard manner, and unsound horses of doubtful breeding have been purchased at high prices and have proven of little value. Where good blood has been introduced the temporary improvement has been marked, but as this work has not been followed up with care, results have not been lasting.
In spite of bad breeding, however, the standard of Utah horses has been advancing so that in western markets they command high pries. The climate, soil, feed and general conditions throughout the state make it an ideal place for the production of horses with excellent feet and legs, great lung capacity and unusual endurance.
