Nothing Found

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.

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 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?

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.

DISCOVERIES, Issue 25: Pathogens commonly associated with swine respiratory disease (SRD) remain highly susceptible to key veterinary antimicrobials,

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.

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.

The findings of a recent study show it’s feasible to obtain data on antimicrobial use while keeping information confidential.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 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.

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 […]

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.

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.

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.
