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, which was foaled in the state around the early 1900s. The breed was officially recognized by the Iowa Department of Agriculture in 1950 and has distinct characteristics, including a cream coat and amber-colored eyes, attributed to the champagne dilution gene. The American cream draft horse is also noted for its strong build and gentle disposition, making it a significant part of Iowa's farming heritage.

In addition to the designation, the resolution mandates that the state records commission collaborate with the American cream draft horse association to acquire and display images and representations of the breed in the state historical museum. Furthermore, 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.
