The RX3 cattle breed is a unique composite beef breed, first established in the 1970s, with a strict genetic program. Its name "RX3" symbolizes the merging of three red American breeds to form a superior recombination. The foundation breeds were chosen for the specific genetic traits they would bring to the new breed, and a new germ plasm pool was created for selecting essential traits for a more complete breed.
The Miles City, MT Livestock Experiment Station used pure Hereford females and bred them with pure Red and White Holstein sires from the Larry Moore Holstein Herd in Suamico, WI, under range conditions in Montana and North Dakota. The Beef Cattle Co. in Johnston, IA, then used pure Red Angus sire Choctaw Chief 373 and his descendants to merge the three breeds. The "Chiefline" strain of Red Angus has remained dominant in the Red Angus Breed's National Sire Evaluation.
The creation of the new breed is being accomplished through rigorous testing and systematic selection for economically important traits. This crucial step will ensure the establishment of a strong and valuable new germ pool for the RX3 breed.
