When a sow doesn’t reach her full potential, the cost to the farm and the income stream of the sow herd is often “grossly underestimated,” said John Deen, DVM, PhD, University of Minnesota.
US producers and veterinarians have seen an influx of different types of influenza viruses in the last 10 to 15 years, and that is a major reason why influenza is more difficult to control.
Researchers at the University of Minnesota have been working on a predictive model to forecast when a disease outbreak may occur on a farm.
Victor Cortese, DVM, PhD, drew on his decades of field experience and expertise in immunology to offer tips for optimizing immunity in swine herds in the face of IAV-S.
DISCOVERIES, Issue 26: It’s well known that modified-live PRRS vaccines help reduce production losses in breeding herds with PRRS. But when the challenge is especially severe, how well and for how long will a PRRS vaccine perform?
The findings of a recent study show it’s feasible to obtain data on antimicrobial use while keeping information confidential.
Cutting-edge molecular technologies offer novel insights into the molecular epidemiology of systemic bacterial agents.
For PRRS, there are benefits to whole-genome sequencing, especially when Orf 5 sequencing doesn’t fully answer important diagnostic questions.

DISCOVERIES, Issue 28: Vaccination as early as 1 day of age with Fostera® PRRS coupled with the vaccine’s long duration of immunity can help pork producers stem the significant economic losses in growing pigs caused by PRRS.
Plan for the worst; hope for the best. That’s good advice for many situations but particularly accurate when it comes to African swine fever (ASF).
Producers and veterinarians should “begin with the end in mind” when it comes to diagnosing disease and planning control strategies, according to Eric Burrough, DVM, PhD, associate professor and diagnostic pathologist at the Iowa State Diagnostic Laboratory.
TOOLBOX, Issue 24: Noel Garbes DVM, senior technical services veterinarian, Zoetis, recently talked with editors of Pig Health Today about measuring modified-live PRRS vaccine efficacy.
Farm staff should be mindful of the role they play in controlling influenza. A University of Minnesota study showed that more than a quarter of farm staff tested influenza-positive at work during peak influenza season.
Eliminating porcine reproductive and respiratory syndrome virus (PRRSV) from pigs might not yet be possible, but monitoring tools could help refine a herd’s PRRSV stability.
TOOLBOX, Issue 22: David A. Baumert, DVM, Senior Area Veterinarian, Pork Technical Services, Zoetis, recently talked with editors of Pig Health Today about Mycoplasma elimination vs control.
On the farm, swine caregivers tend to lump umbilical hernias and umbilical abscesses under the single category of umbilical defects. What are the risk factors for these defects?
Establishing effective internal biosecurity protocols is critical to breaking the circular spread of influenza and other pathogens between sow farms and growing sites, according to Montserrat Torremorell, DVM, PhD, University of Minnesota.
DISCOVERIES, Issue 29: IAV-S continues to frustrate US pork producers. From respiratory problems to reproductive challenges, this rapidly changing virus negatively impacts productivity and profitability.
Searching for strategies to alter the course of pelvic organ prolapse (POP) in sows has been a long, slow climb with progress coming little by little. At the heart of the effort is the Sow Survivability project
Colostrum is vital to piglet survival but managing intake may benefit from some fresh thinking, according to Kara Stewart, associate professor of animal science at Purdue University.
Challenges associated with controlling porcine reproductive and respiratory syndrome virus (PRRSV) have resulted in the increased use of molecular diagnostic tests and sequencing.
DISCOVERIES, Issue 12: The efficacy of Draxxin® (tulathromycin) against key swine respiratory disease (SRD) pathogens is largely due to the antimicrobial’s ability to reach and sustain high concentrations in lung tissue.
The upward trendline of sow mortality needs to be addressed. But until farms have a clearer understanding of why a gilt or sow leaves the breeding herd, progress will be limited.
By Lucina Galina Pantoja, DVM, PhD, Director, US Pork Technical Services, Zoetis
The system used to classify breeding herds according to their PRRSV status has long helped swine veterinarians around the world to track the pathogen’s progress.
It’s not unrealistic to say that if you checked the nasal cavities or tonsils of any group of pigs, you would find Strep suis. It is on virtually every hog farm.
Organizers are excited to hold the 2021 Allen D. Leman Swine Conference in-person as well as virtually, on Sept. 18-21 in St. Paul, Minnesota.
In spite of advanced biosecurity protocols, the porcine reproductive and respiratory syndrome virus (PRRSV) continues to plague global pork producers with unpredictable, seasonal outbreaks.
Water doesn’t get the attention it deserves because it is abundant, easy to access and inexpensive, but that will change in the future, said John Patience, PhD, professor at Iowa State University.
Keeping sow mortality rates in check is critical to a farm’s productivity and cost structure. Yet in recent years, the US pork industry has seen sow mortality rise.
Biosecurity has become the all-inclusive protector of swine herd health. But even with all the biosecurity research, protocols and training, disease outbreaks occur regularly. Why is that?
US producers have seen the devastating impact of African swine fever (ASF) in other countries. The ultimate goal is to keep it out of this country, so industry groups are ramping up preparedness and prevention protocols.
DISCOVERIES, Issue 25: Pathogens commonly associated with swine respiratory disease (SRD) remain highly susceptible to key veterinary antimicrobials,
Effective PCV2 control relies on vaccination of healthy pigs before they become infected. This goal cannot be accomplished in unstable herds whose sows give birth to viremic pigs.
A special report from Pig Health Today, “Integrated Flu Management: New Strategies for Control,” reports on key presentations by experts in influenza A virus in swine (IAV-S) and features highlights of a roundtable involving swine practitioners.
It appears batch farrowing is making a comeback, according to John Deen, DVM, PhD, distinguished global professor at the University of Minnesota.
DISCOVERIES, Issue 20: Pigs with swine respiratory disease due to Actinobacillus pleuropneumoniae were treated with Excede® for Swine (ceftiofur crystallinefree acid) or enrofloxacin in a comparative challenge study.
Multi-disciplinary collaboration by academia, industry partners and the veterinary community is improving the diagnostics for and management of S. suis.
According to research, swine influenza A viruses have become more complicated in recent years. There is a great deal of diversity within the influenza virus.
The “Five Freedoms” have been the foundation for establishing sound animal welfare practices since they were developed in 1965. Now, more than 50 years later, researchers have additional tools and technologies to take that basic knowledge a step further.
In the end, raising hogs is about producing pork, and continuous success depends on building customers’ trust, listening to expectations and meeting their needs.
Influenza A virus in swine is one of the primary respiratory pathogens challenging swine production systems in the US and around the world.
Biosecurity protocols are critical to keeping the US hog herd healthy, and one of the regular tasks is to disinfect a wide range of supplies entering the farm, but how effective are those protocols?
A romanticized view of the veterinary profession, gleaned from sources like the famous Brit, James Herriot’s novel “All Creatures Great and Small,” doesn’t always mesh with the reality.
Pain management for pigs has always been a challenge, partly because it’s difficult to measure levels of pain and partly because there are no FDA-approved drugs labeled for pain management in pigs.
Piglet processing fluids have been shown to be a practical, time-efficient and affordable diagnostic tool for PRRS, and some indications suggest that PCV2 offers promise as well.
Forecasting swine-disease outbreaks might become a lot like predicting the weather as scientists combine monitoring disease data with computer models.
US pork producers should strive to produce influenza-negative pigs if they want to see the benefits of increased productivity, reduced secondary infections and antibiotic use, reduced influenza dissemination, decreased influenza diversity and reduced risk of zoonotic infections.
The farrowing room is a demanding place — one that needs to accommodate the divergent needs of a 500+-pound sow and her 10, 15 or 20 piglets weighing anywhere from 1.5 to 3 pounds.
