Genetic predictions in the form of expected progeny differences (EPDs) represent the beef industry's most powerful source of information for selection and genetic improvement. While EPDs are widely available for traits associated with calving ease, growth, milk and carcass traits, EPDs for reproductive traits are limited. Given the relative economic importance, development of EPDs for reproductive traits should be a priority for the beef industry. Fortunately, recent breakthroughs in analytical procedures have opened the door for potential development of genetic predictions for reproductive traits.
