The National Sheep Improvement Program (NSIP) provides predictable, economically important genetic evaluation information to the American sheep industry by converting performance records into relevant decision-making tools.
By using breeding stock with genetic predictability, all types of flocks have a foundation of genetic information upon which to build a superior and more consistent product to their customers, whether this be a feeder, packer or consumer. This genetic predictability is achievable through NSIP’s Estimated Breeding Values (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.

To obtain EBVs on your sheep, join NSIP today! With EBVs, purebred and seedstock producers can identify genetics that excel in their flocks and greatly accelerates genetic progress within a breed. A flock with any breed type or multiple breed types can submit data for evaluation through NSIP. The data is calculated on the performance of individual animals, related animals in the same flock and related animals in other flocks when possible.
