The first draft of the genome of a domesticated pig has been completed by an international team of scientists who believe this first draft will spur advancements in swine production and human medicine. At 98% complete, the draft sequence will allow researchers to pinpoint genes that are useful to pork production or are involved in immunity or other important physiological processes in the pig. Researchers also believe it will enhance breeding practices, offer insight into diseases that afflict pigs and, sometimes, also humans.
The sequencing project was a collaborative effort involving an international team of scientists and genome sequencing centers. To get the job done it took years and about $24.3 million in investment, including a $10 million dollar investment from USDA and a $750,000 investment from the Pork Checkoff. A Duroc pig from the University of Illinois was used for the sequencing project.
"The pig is a unique animal that is important for food and that is used as an animal model for human disease," said Larry Schook, a University of Illinois professor of biomedical sciences and leader of the sequencing project. "And because the native wild animals are still in existence, it is a really exciting animal to look at to learn about the genomic effects of domestication."
The swine genome sequence is anticipated to accelerate the rate of genetic improvement in swine as the bovine sequence is impacting the dairy industry's genetic gains.
"All U.S. pork producers should be proud of their contribution to this ground-breaking research that is expected to yield dividends for both producers and consumers," said National Pork Board CEO, Chris Novak. "Unlocking the secrets of the pig's genetic code should help secure a brighter future for all pork producers at the same time it is offering insights into human health. That's a victory for everybody."
