What is an Estimated Breeding Value or EBV?
Estimated Breeding Values, often referred to simply as EBVs, are measurements of certain economically-important heritable traits. Based on data collected on participating farms, EBVs are a measure of an individual animal’s performance, but also incorporate performance of related animals in that same flock, as well as related animals in other participating flocks. Scientifically based, EBVs have been tested in several breeds in a wide array of management systems across the U.S. sheep industry. The use of EBVs has been demonstrated to enhance economically-important decisions over visual appraisal alone.
“The backbone of America’s future commercial flock will be a ewe with parasite resistance, low maintenance costs, high fertility/prolificacy and good mothering ability. The National Sheep Improvement Program makes it possible to identify those animals.“
