SVC Veterinarians — Helping to lead the way through the Coronavirus crisis

The hog industry is facing unprecedented times with the  closures of packing plants leading to a severe back up of hogs to be processed in the United States. SVC veterinarians strive to be leaders in times of crisis.

Dr. Tim Loula with Sanford Health has developed a testing algorithm to try to best understand the health status of packing plant workers, and keep the plants open. (See the most recent article in the Farm Journal where Dr. Loula describes using our knowledge of herd immunity and testing to keep plants open or get them back up and running. Herd Immunity in Pigs: A Case Study for Getting America Back to Work. )

As a follow up article for the Farm Journal, Dr. Loula describes the pig industry’s experience with a Chinese Coronavirus, PEDv. The pig industry utilized herd immunity to eliminate PED from sow farm populations. Dr. Loula describes PCR vs. antibody testing (ELISA) in this article and how we can further utilize antibody testing to our advantage.

Drs. Brad Leuwerke and Jake Schwartz led a webinar sponsored by the National Pork Board, “COVID–19, Tools for Managing the Current Situation”. It is a tough decision that producers have to make when they decide to euthanize pigs. Drs. Leuwerke and Schwartz provided insight on how this could be done humanely and effectively.

 

Dr. Jordan Graham has written a proposal to the states of Minnesota and Iowa for support of a swine mass depopulation plan. This plan would provide a safe and humane option for producers to have market hogs euthanized and disposed of in an efficient and environmentally friendly manner. It would also act as the accounting piece in anticipation of a Federal Indemnity Program.


Dr. Paul Yeske along with NPPC and AASV submitted a proposal which could help turn a negative situation for the industry into a positive one. We do not see the packing plants returning to 100% for the foreseeable future, which leaves us with too many pigs and not enough shackle space. If producers are forced to make the decision to euthanize market weight animals, could we turn it into a positive for the industry by possibly reducing disease pressure? They are suggesting just that by developing a program similar to the Accelerated Pseudorabies Eradication Program from the 90’s (APEP). The culling could be targeted towards herds with chronic diseases.

If forced to make the decision to remove swine herds, AASV is encouraging farmers to work with their veterinarians whenever possible and strategically remove populations or herds that have long-term active health problems from endemic diseases. The industry goal of this targeted effort would be to help improve the overall herd health of the entire swine industry. Endemic diseases pose a significant loss in performance and increased vaccination and medication cost to farmers. Minimizing disease challenges also enhances animal wellbeing.

Ideally the industry would be able to work cooperatively with USDA APHIS to structure a program similar to what was used in the Accelerated Pseudorabies Elimination Program (APEP) to help fund this. But with government funding still uncertain, we need to act on our own for now.


Other COVID-19 Resources

Dr. Brad Freking of New Fashion pork lays out nicely the status of the pork industry and the importance of testing 100% of the packing plant employees. In this podcast, Dr. Freking reveals some preliminary results of these tests. 2400 total employees were tested at Triumph Foods. Of the 2400, 750 of the samples have been tested and results revealed 71 COVID-19 PCR positives. The most interesting piece of information is that 90% of those individuals that tested positive, did not have any clinical signs of COVID-19.

Pork industry makes progress on pain management

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.

Can the processing-fluid toolbox expand beyond PRRS?

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.

Take a process-driven approach to influenza control

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.

Committing time, attention to pig’s first 24 hours key to health, uniformity

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.

Swine dysentery makes an unwelcome comeback

Just when US pork producers thought swine dysentery was a problem of the past, it has re-emerged for an unwelcome encore in a slightly different form.

Moving biosecurity from the farm to the feed mill

An effective biosecurity strategy is not a stagnant process. It is continuously influenced by changes in pig-flows, disease pressures, virus evolution, emerging health issues and more.

Ellis: No magic bullet to reduce pre-wean mortality

Pre-wean mortality has increased over the last 15 years, and it’s a major concern for US pork producers and veterinarians.

Outmaneuvering PRRSV requires a better understanding of genetic diversity

PRRSV is constantly evolving, resulting in an extremely diverse virus with multiple lineages, but building a better understanding of that genetic diversity is the next step to making real progress against the disease.

Deen: Apply old lessons to new technologies

Classical education emphasizes the need for industries to adopt new technologies to keep up with external demands and constantly changing economic environments.

Pollmann: Make the most of your human capital

The US pork industry is challenging under the best of circumstances, with enough variables to make even astute, savvy businesspeople cautious. However, one of the biggest components of a successful, healthy operation is human capital.
