We appreciate your interest in learning more about the Katahdin National Sheep Improvement Program (kNSIP) and Estimated Breeding Values (EBVs). EBVs are predictions of an animal’s expected performance and are used by participating members to make selection and culling decisions, reach flock goals, and to improve overall flock performance. To understand more about how this process works, the following documents and educational materials have been developed specifically for Katahdin producers.
The Fact Sheet series below was created to further the understanding of individual EBVs. Some fact sheets describe a single EBV or index: scrotal circumference, maternal weaning weight, and Katahdin Index. Others include related EBVs: weight traits such as birth, weaning and post-weaning weights; fecal egg count EBVs such as weaning and post-weaning FECs; and reproductive traits such as number of lambs born and weaned EBVs. Each fact sheet includes a description of the EBV, how it’s measured and how it can be applied in your flock.
