The National Animal Germplasm Program (NAGP) by USDA's Agricultural Research Service plays a vital role in maintaining genetic diversity for livestock species in the United States. With over one million samples collected from 64,000 animals, the program ensures genetic security and enables researchers, breeders, and the industry to unlock valuable insights into animal genetics and genomics.
Through collaborations and germplasm requests, the NAGP has demonstrated the positive impact of utilizing older generations of sires in breeding programs. A South Dakota beef cattle producer successfully integrated samples from the NAGP repository, resulting in offspring that possess desirable traits and meet production and marketing objectives. Similarly, a study involving Holstein cattle revealed that two unique Y chromosomes, lost in current lines due to selection, significantly influenced milk yields when reintroduced through germplasm samples.
These examples highlight the importance of preserving genetic diversity and utilizing the NAGP collections for research and breeding programs. The program's repository extends beyond livestock, including aquatic animals, poultry, and insects. By harnessing genetic resources, the NAGP contributes to enhancing animal performance, resilience, and understanding the genetic basis for livestock productivity.
