History of National Swine Registry

National Swine Registry (NSR) formed in 1994 as a result of the consolidation of the American Yorkshire Club, the Hampshire Swine Registry and the United Duroc Swine Registry. In January 1998, the American Landrace Association joined the NSR.

This consolidation effort allowed for increased efficiency in the services offered to purebred breeders through the elimination of duplicated resource allocation, and established a unified approach to the future development of programs and services for each of the four breeds.

These four breed organizations are located in one central office in West Lafayette, Ind. Below is a current depiction of the current NSR membership demographics, and show the NSR includes a membership base that represents nearly all of the states in the continental U.S.

The NSR's services include litter registrations, performance pedigrees, breed promotion and marketing assistance. As well, the NSR has created various educational materials, including a swine-judging video. The NSR is capable of meeting all of your genetic needs, including free genetic consultation, across-herd genetic evaluations, and a National Four-Breed Sire Summary. This National Sire Summary is published every six months and includes all trait leaders in each breed.

The four breeds comprising the NSR are making significant contributions to the overall profitability of the swine industry. Hampshires, Landrace, Durocs and Yorkshires represent 87 percent of the total purebred hog population in the United States.

Our Breeds

Each of the respective breed associations that comprise the National Swine Registry have a long and rich history that goes back to the 1800's. During the time when each association operated as a separate entity, the general oversight and development of each breed was governed individually.

In the earlier stages of the purebred seedstock industry in the U.S., breeders typically raised and sold one breed of hogs. Over time, these breeders began to take part in more than one organization, as the average seedstock supplier maintained several breeds on their farm to meet the demands of the U.S. commercial producer. As this trend increased throughout the 1970's and 1980's, an increase in the level of sophistication of commercial clients was also taking place. As the commercial clients of purebred seedstock suppliers began to utilize more specific crossbreeding programs, this ultimately placed increased pressure on the seedstock supplier, and ultimately, the needed services offered by breed organizations.
