The ASA, in cooperation with the Animal Breeding Group at Cornell University and the Center for the Genetic Evaluation of Livestock at Colorado State University, evaluated the progeny of over 100,000 sires, representing in excess of four million individuals. Based on those evaluations, Expected Progeny Differences (EPDs) are published in the summary on over 900 of the most popular sires. Information on all other sires can be accessed at www.simmental.org.

The Fall 2006 Sire Summary represents the 19th official run of the innovative Multiple-Breed International Cattle Evaluation (MB-ICE) system. Developed jointly by ASA and Cornell University, MB-ICE was the industry's first multi-breed genetic evaluation. It was developed to accommodate the needs of ASA members and their customers to better utilize breed complementarity in their crossbreeding programs. ASA EPDs are expressed on a single base regardless of breed makeup, thereby making cumbersome across-breed EPD adjustments unnecessary.
