The Stenhammar Estate breeds Simmental, Aberdeen Angus and Simgus cattle. Breeding projects are underway between the Simmental and Aberdeen Angus breeds at Stenhammar, in collaboration with the Swedish University of Agricultural Sciences. The resulting cross breed is called Simgus. These breeds are well suited to cattle-rearing under Swedish conditions. They create open landscapes and healthy animals.
The King has been pursuing organic livestock farming at Stenhammar since 2005.
