Angelo State University's athletic teams are proud to have as their mascot the mighty Ram.

While many other universities feature a big horn ram as a mascot, ASU is unique in that its mascot is the domestic Rambouillet sheep, a compact white-wooled animal with long curving horns.

The Rambouillet sheep breed originated in Spain over two centuries ago with the famed Merino flocks of that country. Exportation of the valued sheep, known to be a producer of the finest wool in the world, was forbidden by the Spanish government until 1786. The exportation ban was finally lifted by the King of Spain and a small herd was sent to the Rambouillet farm near Paris, France. The breed is still bred at the farm to this day, using stock descended from the original herd shipment from Spain.

The City of San Angelo is the headquarters for the Texas Sheep and Goat Raisers Association and is considered the top breeding center for the sheep in the United States. There are numerous Rambouillet ranches in the San Angelo. San Angelo remains one of the major buying and shipping centers for the fine Rambouillet wool.

The ASU Agriculture Department maintains a flock of the sheep that has been honored with various regional, national and international awards over the years at wool and sheep competitions. One of the rams from this herd serves as a mascot at each of the Ram home football games. The ram, nicknamed "Dominic," stands on the sidelines with his agricultural student handlers.

In addition to Dominic, the costumed Roscoe D. Ram attends nearly all home ASU athletic events to represent the spirit of all Ram and Rambelle fans. Roscoe has been honored through the years as one of the top mascots in the country at various cheerleading and spirit camps. He also helps future mascots from around the area with mini-camps in the summer.
