Acceligen Announces Innovative Scientific Paper on Breeding PRRSV Resistant Pigs


EAGAN, Minn., Jan. 16, 2024 /PRNewswire/ — Acceligen, the leading Precision Breeding company for food animals, today announced publication in Antiviral Research of their groundbreaking work on breeding PRRSV resistant pigs.

Porcine Reproductive and Respiratory Syndrome Virus, also known as PRRSV, is a virus which results in substantial economic harm to pig farms on a global scale. Causing as extensive as $664 million in direct losses in the United States and reaching up to 1.5 billion Euros annually in Europe. Additionally, the animals may exhibit clinical signs inclusive of a phase of reduced appetite, fever, lethargy, depression, and possibly respiratory distress or vomiting.

Effective treatments are currently unavailable and modified-live vaccines offer only partial protection from a rapidly spreading infection. There are various mitigation strategies if a swine operation is infected, including herd closure or complete depopulation. Both options can incur expenses and raise concerns about the well-being of the animals.

Here at Acceligen, we believe that animals that nourish us deserve the best in health and well-being.  The publication shows that Acceligen is meeting this challenge by uniquely breeding pigs resistant to PRRSV-1 and PRRSV-2.

Professor Raymond (Bob) Rowland at the University of Illinois, a senior author on the paper and a world-recognized expert on PRRSV said, “It is very rare in swine disease research to have an idea evolve from a concept outlined on a piece of paper to a new product that will help producers eliminate a dreaded disease.  None of this would have been possible without the partnership with Acceligen.”

Dr. Tad Sonstegard, co-author and CEO of Acceligen said, “The results of this research demonstrate that Acceligen’s approach to breed PRRSV resistant pigs opens an alternative avenue for making this trait available to the entire industry.”

“The economic impact of utilizing PRRSV-resistant pigs may be positive and significant for the pork industry, eliminating the need for severe mitigation strategies and costly care. Ultimately, a healthier pig population contributes to a more sustainable and economically viable swine industry,” commented Rocco Morelli, CEO Recombinetics Inc.

Acceligen primarily functions in the livestock gene-editing industry, providing livestock improvements for animal health and well-being that in turn empower farmers to increase sustainable production.
