(BIVI). ... Early Vaccination Key to managing PRRS in the NurseryNebraska swine practitioner John Waddell realized early on a battle against porcine reproductive and respiratory syndrome (PRRS) in the nursery would require a “systems approach.”... National Pork Board Initiatives for PRRSThe National Pork Board (NPB) will spend $1.25 million this year for PRRS Initiative research. Once a year, the board calls for proposals involving PRRS... Assessing the Risk of PRRSThe PRRS Risk Assessment Tool for the Breeding Herd is a Web-based program veterinarians use to separate important from not-so-important factors that may predispose a farm to a higher probability of clinical PRRS... Consider Subclinical PCV2 if Performance DragsFrom a microbiological standpoint, porcine circovirus type 2 (PCV2)is a small, relatively slow-growing virus... Vaccine Proved to be Turning Point for Harrison Creek FarmWhen disease struck in February of 2006, the Brinker family of Calloway County, Mo., knew their sow operation was in trouble... Diagnosing Circovirus Takes a Little MAGICDisease associated with porcine circovirus type 2 (PCV2) is a complex mix of clinical signs and tissue lesions. The pathogen has been in U.S. swine populations for decades, but is emerging as a virulent epidemic with a new name – porcine circovirus associated disease, or PCVAD... Coinfected Herds: Two Case StudiesSouthern Minnesota veterinarian Tom Wetzell had several herds participate in MAGIC™, which stands for Monitoring Assignment for Global Insight of Circovirus. MAGIC is a diagnostic protocol to root out porcine circovirus type 2 and its coinfections... 2007 Boehringer Ingelheim Advancement in PRRS Research Award Recipients AnnouncedBoehringer Ingelheim Vetmedica, Inc., is committed to learning more about understanding and managing the PRRS virus... PRRS Risk Assessment ToolA web-based version of the PRRS Risk Assessment Tool for the Breeding Herd is in development and should be available online this summer... Finishers Benefit from PRRS ProtectionJust when many U.S. sow herds are reaching a state of PRRS stability, the virus is cropping up elsewhere along the production chain... PRRS Protection in Commingled Pig FlowsIf there is strength in numbers, a field study conducted by Boehringer Ingelheim Vetmedica, Inc. (BIVI), should leave little doubt as to the impact of Ingelvac PRRS ATP... Managing PRRS Virus in Commingled Pig FlowsCombining nursery pigs from different sources can present several challenges to managers of grow-finish farms... Proper Diagnosis A PCV2 ChallengeIn a PMWS surveillance study sponsored by the National Pork Board, 10 veterinarians submitted a specified set of tissues from a total of 100 cases that they felt... PMWS confused With PRRSWhen the first cases of severe PMWS suddenly appeared in Quebec in 2004, many practitioners thought these cases were an emergence of atypical PRRS, recalls Francois... Respiratory Vaccines, Timing Impact PCV2Type 2 porcine circovirus (PCV2) is now associated with several diseases, including postweaning multisystemic wasting syndrome (PMWS), reproductive disorders, porcine... Practitioners Take New Look At Disease ComplexThere are several schools of thought as to why porcine circovirus type 2 (PCV2) is identified as the cause of mortality in so many pigs, even though the virus has been present in... 2005 Marks Historical Changes in Swine Disease ControlIf the one constant in swine production is change, then the industry has certainly experienced its share over the past 25 years. This change, driven by... Overcoming the complex immune response to PRRSAlthough PRRS was originally called Mystery Disease in part out of frustration at researchers' inability to discover its cause, the name still applies... Another tool in the PRRS-management toolboxThe United States Department of Agriculture has approved the use of Ingelvac PRRS MLV vaccine for whole-herd (boars excluded) vaccination in PRRS-positive... Using mass vaccination to stabilize the herdIn an unstable herd, PRRS virus regularly cycles from pockets of infected sows to susceptible sows or gilts. Those breeding animals then infect offspring,... What about heterologous protection?Because PRRS shows such ability to mutate, the natural question arises: Can a mass-vaccination program protect animals if a differing strain is introduced?... Testing your progressTo accomplish ideal control, vaccination, medication and management changes must be timed to their ideal point in the disease cycle. Effective testing... If not continuous medication, then what?To live with endemic disease those you can't practically eradicate or keep out of a pig flow continuous antibiotic feeding has been the traditional mainstay.... Challenges to PRRS virus managementPerhaps more than any other production disease, PRRS demonstrates the need for a step-by-step, systematic approach to control. The unique nature of the... |
