Marvin was light, red roan. He was large, powerful, but very dairy. He was very sharp, smooth, well blended, and very wide throughout. Not only did his progeny have well attached udders, they milked! In spite of his size and power, he was very gentle. In fact, he was nicknamed the "Gentle Giant”. His offspring inherited his fabulous disposition. Marvin's greatest attribute was his ability to pass on all these wonderful qualities; he was genetically pre-potent.
