Hasbargen Land & Cattle

The National Sheep Improvement Program (NSIP) was founded in 1986 to "To provide predictable, economically important genetic evaluation information to the American sheep industry by converting performance records into relevant decision-making tools."

​

They favor a data based approach to improving sheep flocks and collect multi-generational performance and carcass data to generate their EBV's which give  growers a prediction of progeny potential.  Heritable traits are measured and tracked to improve carcass, reproductive, and flock health for with increasing consistency across all breeds. This data allows for the identification of individual flock strengths and greatly accelerates the genetic progress within breeds.
