The Market…The Global Market

Global Industry
• The U.S. Swine Herd and its producers rely on the export market for a large amount of their sales
• Therefore, foreign countries that buy our pork are our customers
• As the saying goes, “The customers are always right”
![Page 7: This Little Piggy Went to Market](https://reader035.vdocuments.us/reader035/viewer/2022070410/5681466b550346895db38fbb/html5/thumbnails/7.jpg)
Global Market
• Japanese Market: > $1billion in exports
• A single animal violation in antibiotic in the meat may lead to a severing of this relationship for a period of time
• This would lead to drastic decrease in price of pork received by U.S. producers
• Japanese MRL’s require longer withdrawal periods than U.S. Withdrawal Periods

U.S. vs Japanese Withdrawal Periods

Clinical Signs
• There is an increase in acute mortality ranging around two to three weeks in duration.
• There are fallout pigs that will become sub-standard pigs at market.
• Two pigs that were seen today had skin lesions indicative of the PDNS form of circovirus.
• There is diarrhea that is commonly associated with circovirus.
• There are swollen legs that are commonly seen with circovirus infection.
• There is a respiratory component to this disease as well.

Diagnostics
• Histopathology: Skin - multifocally the superficial epidermal layers are ulcerated and also replaced by necrotic debris, neutrophils and fibrin. There is moderate to marked perivascular inflammation of the vessels in the superficial dermis. Spleen - multifocally, vessels are undergoing fibrinoid vascular necrosis. Kidney - multifocally, glomeruli are undergoing fibrinoid vascular necrosis. There is protein in the urinary spaces. There is interstitial nephritis with lymphocytes. Lymph node - germinal centers are replaced by granulomatous inflammation and multinucleated giant cells. Lung, jejunum, heart and liver - there are no visible lesions.
![Page 29: This Little Piggy Went to Market](https://reader035.vdocuments.us/reader035/viewer/2022070410/5681466b550346895db38fbb/html5/thumbnails/29.jpg)
Diagnostics, cont.
• Bacteriology: There is no significant growth from the intestine, lung or lymph node. There is no growth from the kidney, liver or skin. There are no Salmonella sp. isolated.
• Molecular Diagnostics: PCR tests for PRRS virus and type 2 circovirus are positive.
![Page 30: This Little Piggy Went to Market](https://reader035.vdocuments.us/reader035/viewer/2022070410/5681466b550346895db38fbb/html5/thumbnails/30.jpg)
Diagnostic Summary
• Skin, perivasculitis and epidermal necrosis, consistent with PDNS.
• Kidney, necrotizing glomerulitis and interstitial nephritis, consistent with PDNS.
• Histiocytic and granulomatous lymphadenitis, type 2 circovirus.
• PRRS virus infection. • Comments: Lesions in the tissues are consistent with
PDNS and PCVAD
