Genomic-enhanced EBVs

Welcome to the Genomics Page!

In 2020, the Katahdin Hair Sheep International (KHSI) organization won an NSIIC grant to launch the first-ever NSIP genomics project in the U.S. The breed was able to leverage an existing “reference population” that was DNA-sampled in a previous study on parasite resistance, headed up by Dr. Joan Burke at the USDA research station in Booneville, AR. In 2021, we are ready to expand the project to include more participants from the Katahdin producer community, to produce our first NSIP “GEBVs” or Genomic-enhanced EBVs. Though producers will bear the cost of sample collection and processing, the grant will help fund longer-term sample storage, project coordination and other start-up costs.

Check back here to see information on the project and read about our progress!

What Are EBVs?

EBVs are science-based, industry-tested measurements of heritable traits that can be tracked and measured. For those familiar with Expected Progeny Differences (EPDs) used in cattle, EBVs are very similar. EPDs denotes the breeding value of an individual animal’s progeny whereas EBVs denote the value of the individual animal. More simply, EBVs equal EPDs times two.
