The community of Polypay breeders is active and continues to grow to develop the breed. Currently, there are about 100 members of the American Polypay Association and there are typically about 1,500 animals registered each year. In 1987, the National Sheep Improvement Program (NSIP)] was initiated and included the Polypay breed. Through the efforts of the breeders enrolled in the program, breeders have been able to significantly enhance the breed characteristics. There are currently 41 breeders and 1,244 animals were added to the NSIP in 2016. There are nearly 14,000 animals in the registry. Each year there are national sales that highlight the breed in Sedalia, MO, Spencer, IA and Wooster, OH. These sales incorporate traditional conformational characteristics as well as estimated breeding values (EBVs) generated through the NSIP.
