Researchers from the University of Missouri, Kansas State University and Genus plc have combined efforts to create pigs that are resistant to porcine reproductive and respiratory syndrome virus....More
Colder weather brings its own unique challenges to swine production. In addition to increased demands on pig performance and production, incidence of respiratory diseases, such as porcine reproductive and respiratory syndrome, also tend to increase during winter months....More
Boehringer Ingelheim Vetmedica Inc. is again seeking study proposals from swine veterinarians, diagnosticians, and public and private veterinary researchers in the United States, Canada and Mexico for its Advancement in PRRS Research Awards. Selected research programs are designed to investigate new ways to diagnose, control and eradicate one of the world’s most costly swine diseases....More
On Sept. 9 Merck Animal Health announced the introduction of Prime Pac PRRS+, a vaccine for reducing clinical signs of reproductive disease in female breeding-age swine and respiratory disease in pigs three to four weeks of age and older due to porcine reproductive and respiratory syndrome virus....More
While seeking more information, we recently designed a study to measure the size of particles that are associated with influenza, porcine reproductive and respiratory syndrome (PRRS) and porcine epidemic diarrhea virus (PEDV)....More
To clean up sow breed-to-wean herds when they turn positive for porcine reproductive and respiratory syndrome (PRRS) in the fall, the Pipestone (MN) Veterinary Clinic has developed best practices to be incorporated into a standard protocol for disease elimination in its production network. It’s called the Pipestone System. The goal for each newly infected farm is to follow this protocol to eliminate the field virus, said Joel Nerem, DVM, Pipestone Veterinary Clinic (PVC)....More
Building on a 10-year history as the International Porcine Reproductive and Respiratory Syndrome (PRRS) Symposium, the Pork Checkoff recently cosponsored the 2013 North American PRRS Symposium in Chicago. The meeting drew 200 participants from across North America and beyond to share the latest research and insights into PRRS. The disease costs the U.S. pork industry $664 million per year or $115/sow, according to previous research by Iowa State University....More
Boehringer Ingelheim Vetmedica, Inc. has announced its annual call for proposals for PRRS (porcine reproductive and respiratory syndrome) research to further knowledge on this “costly, frustrating challenge to the global swine industry,” the company says.
The deadline for submissions is Jan. 1 of each year....More
A team of researchers at the University of Minnesota recently concluded analysis of preliminary data on the effectiveness of electrostatic particle ionization (EPI) technology on decreasing artificial infectious aerosols....More
Minnesota swine veterinarian Gil Patterson looks for three things when he walks into a hog barn: feed, water and air quality.“You’ve got to have those things right before you can really dig into other issues. If there is a dusty, poorly ventilated environment, then it is uncomfortable for both pigs and farm employees, often leading to reduced growth and poorer-quality chores,” says the St. Peter, MN, Swine Vet Center clinician....More
The Ohio Pork Producers Council (OPPC) has organized the nation’s first state PRRS Task Force, says Dick Isler, executive vice president of the OPPC.
“As far as we know, this is the first time this has been done in the country,” Isler says. The group consists of the state’s swine veterinarians, pork producers, allied industry and other pork industry stakeholders....More
Zoetis has awarded a $100,000 PRRS Innovation Research Grant to Kyoungjin Yoon, DVM, and Jianqiang Zhang, MD, investigators at Iowa State University College of Veterinary Medicine, to conduct research into virus characterization and the immunobiology of porcine reproductive and respiratory syndrome (PRRS)....More
While looking over some of the headlines from the past week, it occurs to me that most pork producers are probably only one disease outbreak away from developing a healthy appreciation for their local vet school or veterinary diagnostic laboratory. As a child, I remember watching in complete fascination when our vet would come to our farm to “post” (conduct a postmortem) on a pig. I also remember hearing phrases like, “We’ll know more after we send this sample to Brookings.” South Dakota pork producers like my father have been lucky to have a resource such as the South Dakota State University Veterinary Diagnostic Laboratory, located in Brookings, SD, at their disposal over the years....More
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
