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.

A new variant of the porcine reproductive and respiratory syndrome virus 1-4-4 L1C strain is challenging veterinarians, diagnosticians and swine herds in the upper Midwest.

TOOLBOX, Issue 23: Noel Garbes DVM, senior technical services veterinarian, Zoetis, recently talked with editors of Pig Health Today about monitoring swine herds for PCV2.

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.

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.

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.

Researchers at the University of Minnesota have been working on a predictive model to forecast when a disease outbreak may occur on a farm.

DISCOVERIES, Issue 22: A robust body of research explains the efficacy of Excede® for Swine (ceftiofur crystalline free acid) against four of the bacterial pathogens associated with swine respiratory disease.

Pig health and performance begin with the sow, which is why it’s critical for caregivers and production managers to evaluate each sow’s health, body condition, comfort, behavior and well-being as part of their daily routine. “By training workers, we can help them reduce sow mortality rates and culls, improve sow performance, stabilize the health status […]

TOOLBOX, Issue 21: Rick Swalla, DVM, recently talked with editors of Pig Health Today about regulations concerning extra label drug use.

DISCOVERIES, Issue 24: An analysis of three similar injectable antibiotics used for swine respiratory disease pathogens demonstrates that resuspension times can differ substantially.

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.

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.

DISCOVERIES, Issue 18: Obtaining cycle threshold (Ct) values based on processing fluids provides a practical way to identify neonatal pigs at risk for nursery mortality associated with PRRS and can help determine when vaccination is worthwhile.

It appears batch farrowing is making a comeback, according to John Deen, DVM, PhD, distinguished global professor at the University of Minnesota.

Multi-disciplinary collaboration by academia, industry partners and the veterinary community is improving the diagnostics for and management of S. suis.

DISCOVERIES, Issue 21: A recent analysis of porcine circovirus type 2 (PCV2) genetic sequences shows that up to 25% of field strains are recombinants of diverse genotypes, highlighting the importance of broad protection when selecting a PCV2 vaccine.

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.

DISCOVERIES, Issue 19: PRRS has been described as one of the most important swine diseases of the last half-century. An estimated 20% to 25% of herds are still affected, and the syndrome remains the US swine industry’s most costly disease.

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.

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.

COVID-19’s global-altering tentacles reached the 2020 Allen D. Leman Swine Conference scheduled Sept. 19-22. This year’s conference will be held virtually.

The first case of Streptococcus equi subsp. zooepidemicus (Strep. zoo) was identified in the US pig population last fall, and it’s not an organism to be taken lightly.

Sow mortality has been on the rise in the US pork industry, reaching upwards of 15% in many sow-production systems, said Ashley Johnson, DVM, technical services veterinarian with Zoetis.

Whether the issue is an emerging disease such as porcine epidemic diarrhea or the threat of African swine fever, being prepared is key to minimizing the potential impact on the US swine herd and expediting the recovery.

Veterinarians deal with stress under the best circumstances. But in this time of difficult decisions for pork producers and those who service them due to COVID-19, maintaining mental health is even more of a concern.

For both the sow and piglet, an animal that does not perform to its potential or falls behind its counterparts will negatively impact the sow farm’s productivity and profitability.

Clinical problems in swine due to antimicrobial-resistant infections are rare. In fact, patterns of resistance in swine have been stable for a long time.

Many sow farms have undergone M. hyo elimination within their breeding herd, which makes it critical to understand the potential transmission risk from boar studs.

Few things remain the same for long on a hog farm. By the very nature of today’s production system, pigs are continuously moving on or off a site. One thing that remains constant is Strep suis.

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.

Porcine circovirus type 2 is the principal etiological agent of porcine circovirus associated disease (PCVAD), which can cost producers an estimated $3 to $4 per pig.

Preventing fomites from carrying pathogens into hog farms is a daily biosecurity priority, but how effective are typical disinfection protocols?

Streptococcus suis (Strep suis) is becoming more prevalent and more complex in US swine herds. The coccoid-shaped, Gram-positive bacterium is also a zoonotic disease, capable of transmission from pigs to humans.

When it comes to porcine reproductive and respiratory virus it’s important for the veterinarian and farm personnel to know the health status of a herd or barn.
