The breeds of swine found and developed in the United States are unique in their ability to perform consistently under a variety of weather conditions and management styles. This consistent performance is the result of years of painstaking work by geneticists, breeders and commercial producers who were committed to do what was necessary for true genetic progress to become a reality. That commitment remains as strong as ever.
- Pork production is a vital part of the U.S. economy.
- Nearly 8.6 billion kilograms were processed from about 97 million hogs in 2001.
- Approximately 80 percent of the U.S. hogs are grown on farms that produce 5,000 or more hogs per year.
- The U.S. is one of the world’s leading pork-producing and exporting countries, accounting for about 10 percent of the world’s supply.
TECHNOLOGY DRIVES U.S. GENETIC PROGRESS
- U.S.breeders rely on hard data to serve as the core of their genetic decisions.
- Majority of the data is gathered at the farm level.
- Many breeders use ultrasound technology to assist in making genetic decisions.
- Precision equipment, coupled with genetic rating systems, allows breeders to accelerate genetic progress by assigning numerical values called EPDs (Expected Progeny Differences) to economically evaluate important genetic traits.
- Quick and accurate comparisons of individuals on a trait-by-trait basis within a breed are possible.
- Many breeders are using techniques like artificial insemination, Medicated Early Weaning and Segregated Early Weaning, all-in/all-out pig flow, separate-sex feeding and multi-site production – protocols that enhance genetic progress.
QUALITY PORK FROM HEALTHY ANIMALS
- The health and welfare of animals is a key concern of U.S. pork producers.
- Healthy animals whose welfare is carefully respected result in safe, wholesome, high quality pork products.
- As a consequence of superior herd health, many purebred breeders use little, if any, antibiotics in their herds, ensuring true genetic expression unaltered by feed additives or other pharmaceuticals.
- When you invest in U.S. genetics, you’re ensuring top-rate health status for your operation.
THE BREEDS TO BUILD ON
Four breeds of swine in the United States are recognized as setting new standards in genetic progress. They possess the most desirable carcass and production traits sought by breeders and producers the world over.
The four breeds – Duroc, Hampshire, Landrace and Yorkshire – form the backbone of the U.S. swine industry. These four breed organizations are located in the central office of the National Swine Registry, where services such as registration, performance pedigrees and national sire summaries are performed.
- An estimated 80 percent of all U.S. commercial pork producers use at least one of these four breeds.
- 65 percent use two or more of them.
- U.S.producers know they can depend on these genotypes to deliver maximum performance.
