A new porcine reproductive and respiratory syndrome (PRRS) vaccine, developed by Ohio State University (OSU) researchers, uses biodegradable nanoparticles to deliver an inactivated virus intranasally....More
Data from Steve Tousignant, DVM, at the National PRRS virus Incidence Project at the University of Minnesota, documents that annual epidemics of porcine reproductive and respiratory syndrome are repeatable.
This is evidenced by a study that recorded the number of new PRRS virus cases in 370 sow herds across 14 unique production systems. For the past four years, the number of new cases on a weekly basis was expected to dramatically rise in mid-October (see graph)....More
With current vaccines of limited value in the fight against porcine reproductive and respiratory syndrome (PRRS), a National Taiwan University (NTU) team took a different tact. They developed transgenic bananas to orally vaccinate swine against PRRS, which they consider a major breakthrough with great economic potential, the Republic of China National Science Council (NSC) said July 17....More
Porcine reproductive and respiratory syndrome (PRRS) virus costs U.S. swine producers more than $664 million annually in lost production. Collaborative scientific research continues to be the industry’s best hope for finding new ways to mitigate this devastating disease. ...More
Scientists from the University of Missouri and Kansas State University are collaborating to find a cure for porcine reproductive and respiratory syndrome (PRRS), a disease that costs the swine industry an estimated $800 million annually.
In their latest study, the team disproved one way the virus spreads, which will help scientists narrow the search for an ultimate cure....More
Veterinarians with Boehringer Ingelheim Vetmedica, Inc. (BIVI) introduced a new concept of disease control at the recent World Pork Expo.
Dubbed the Infection Chain, the concept is designed to minimize the impact of porcine respiratory disease complex (PRDC) in pigs and throughout the production system....More
Porcine reproductive and respiratory syndrome (PRRS) virus entered the United States in the late 1980s. Through the years, the virus has mutated, evolved and recombined to create hundreds of virus strains today....More
Porcine reproductive and respiratory syndrome (PRRS), a devastating disease in pigs, causes significant losses to the swine industry worldwide each year. The ability of the PRRS virus to persist and evade a host’s immune response has USDA Agricultural Research Service (ARS) scientists digging deeper into the molecular and cellular mechanisms of the disease....More
A disclosure of porcine reproductive and respiratory syndrome (PRRS) status of swine is now requested as part of the import permit process. The new disclosure requirement, which became effective March 1, comes as a result of a 20-month initiative by the Wisconsin Pork Association’s (WPA) PRRS Committee to control the spread of the disease.
Disclosure is made on the Certificate of Veterinary Inspection and the import permit application, which are submitted and reviewed before a permit is issued....More
New Zealand’s Court of Appeals last week rejected the New Zealand pork industry’s (NZPork) appeal of a decision issued by the country’s High Court last May that further liberalized market access for U.S. pork. The High Court found in favor of the New Zealand Ministry for Primary Industries and its Import Health Standard (IHS) for pork, pork products and by-products from countries with porcine reproductive and respiratory syndrome (PRRS), including the United States....More
Boehringer Ingelheim Vetmedica, Inc. (BIVI) announces the 2013 recipients of its annual Advancement in PRRS Research Awards. This year, BIVI awarded $75,000 to support three separate studies by independent swine researchers and practitioners in their investigations of novel ways to diagnose, control and eliminate this costly swine disease....More
Grant funds totaling up to $250,000 are available for projects that advance and enhance swine production in Iowa, according to Iowa Attorney General Tom Miller. Proposals are due by April 19.
The grant money is for the seventh year of a program funded by Smithfield Foods, which is paying $1 million over 10 years for the program. Miller released a “Request for Applications” (RFA) to identify and support innovative Iowa projects eligible for the grants....More
If you are serious about staying ahead of porcine reproductive and respiratory syndrome (PRRS) virus, then it’s time to tighten biosecurity measures and take aggressive steps to protect your operation from the virus.
That’s the message from Cameron Schmitt, DVM, Pipestone Vet Clinic of Iowa, based at Independence....More
Recently, the National Pork Board (NPB) facilitated a meeting of North American pork industry researchers, pharmaceutical and biological company representatives, veterinarians and diagnosticians to discuss the future of porcine reproductive and respiratory syndrome (PRRS) in swine production, according to a report from Harry Snelson, DVM, American Association of Swine Veterinarians.
The intent of this meeting was to develop a roadmap for future activities for PRRS to include:...More
Approximately 20-plus years into the fight to rid the nation of porcine reproductive and respiratory syndrome (PRRS) virus, a more realistic approach may be to improve efforts to control the persistent disease....More
State officials announced late last week that effective March 1, swine entering Wisconsin must be accompanied by an import permit. To successfully acquire this permit, a veterinarian must disclose the porcine reproductive and respiratory syndrome (PRRS) status of the herd of origin, if known, with a statement on the certificate of veterinary inspection (CVI)....More
Tissues, blood, feces and serum have historically been the samples needed to perform most diagnostic tests. But in the last few years, oral fluids have proven to be useful samples for detecting certain pathogens circulating in groups of pigs....More
A team of researchers at Iowa State University (ISU) has received a $3 million grant to study genetic resistance to the costliest disease threatening the pork industry and transfer this technology to the industry.
The researchers, led by Jack Dekkers, an ISU professor of animal science, will seek to identify genes in pigs that make them less susceptible to porcine reproductive and respiratory syndrome (PRRS), a viral disease that costs U.S. pork producers about $664 million a year....More
In a national effort to assess the role of genetics in determining pig resistance/susceptibility to PRRS virus infection and related pathology and growth effects, the PRRS Host Genetics Consortium (PHGC) was formed. By collecting data on large numbers of PRRS virus-infected pigs, researchers aim to identify and verify important genotypes and phenotypes that predict resistance, tolerance or susceptibility to viral infection....More
A study at the University of Minnesota compared the PRRS outbreak history of 20 filtered and 17 control (non-filtered) sow farms. Data was collected from October 2004 to June 2011. The information encompassed 120,000 sows from high-density regions in the Midwest....More
In the largest field study of its kind, a team of University of Minnesota researchers evaluated the impact of immunization in herd closure strategies on eliminating porcine reproductive and respiratory syndrome (PRRS) virus from breeding herds....More
