The resolution designates the American cream draft horse as the official state horse of Iowa. This breed is unique to the United States and has historical ties to Iowa, tracing its lineage back to a mare named Old Granny, foaled in the state around the early 1900s. The breed was officially recognized by the Iowa Department of Agriculture in 1950, and the American Cream Horse Association was established in 1944, reflecting a long-standing interest in developing this distinct draft horse breed. The American cream draft horse is characterized by its cream coat, pink skin, and amber-colored eyes, and is known for its strong build and gentle disposition, making it a symbol of Iowa's agricultural heritage.

The resolution also outlines provisions for the Iowa State Historical Society to collaborate with the American Cream Draft Horse Association to display images and representations of the breed in the state historical museum. Additionally, the Iowa official register will include a picture and commentary about the American cream draft horse, alongside other state symbols such as the state rock, flower, bird, and tree. This initiative aims to honor and promote the significance of the American cream draft horse within Iowa's cultural and historical context.
