Data from over 3000 animals from two large sire breed comparison studies were used to estimate breed differences and adjustment factors necessary for the development of multi-breed BREEDPLAN estimated breeding values (EBV) for Angus, Hereford, Limousin and Simmental breeds for several growth traits. Theses included gestation length, birth weight, 200d weight, 400d weight, 600d weight and carcase weight. The adjustment factors can be used by industry to construct a conversion table that can be used to directly compare the EBVs of animals across the four breeds. This table should enhance the use of both between and within breed genetic variation, however all traits affecting profit will need to be considered, not just growth trait comparisons. Further research is underway to add more traits and breeds.
