• Today– The veterinarian in Denmark– Vaccination in Denmark– Veterinary management in swine practice– Questions

• The private veterinarian• Independent of medicine, feed and other products
– regulated by law.• Farmer pays the vet. by the hour.• If vet does not solve the problem – farmer will find
other vet. – free market

Vaccinations• Live vaccines
– long lasting, dangerous, one-shot.– PRRS, Lawsonia
• Killed vaccines– F.eks. Mycoplasma, Influenza– Safe, often two shot.
• Autovaccines– Greasy pig disease – Mastitis– Umbilical Hernia– Streptococci

Sow• Clostridium perfringens type C – 98%• Clostridium perfringens type A – 10%• Erysiopelotrix rhusiopatihae – 99%• Parvo virus – 95%• Escherichia coli – 50%• PRRS – 5%• Influenza -10%• PCV2 – 2%• Actinobacillus pleuropneumoniae - 5%• Leptospirosis – 5%• Autovaccines – 1%

Weaners, growers and finishers– Mycoplasma hyopneumoniae - 50%– Actinobaccilus pleuropneumoniae - 2%– Lawsonia intracellularis – 5%– PCV2 – 5%

Veterinary Management• Problem (Lung disease/reproduction/diarrhea)
– Investigation (Autopsy/blood samles)– Diagnosis– Primary cause (Bacteria/Virus)– Treatment/Vaccination
– Secondary cause• Bacteria/Virus• Stable• Management• Feed
![Page 11: Vets and Vaccines](https://reader036.fdocuments.net/reader036/viewer/2022062302/568163e4550346895dd54374/html5/thumbnails/11.jpg)
Example
• I am called because 10 animals died over the night
One stable with 1000 finishers and new pigs every 3rd week. Problem with high mortality and low growth
![Page 12: Vets and Vaccines](https://reader036.fdocuments.net/reader036/viewer/2022062302/568163e4550346895dd54374/html5/thumbnails/12.jpg)
Example• Autopsy shows signs of AP• Laboratory answer confirms AP
type 6• Treatment
– All animals treated with penicillin or amoxicillin
• Prevention– Vaccination against AP (not very
efficient)– Antibiotic treatment of all new pigs
(expensive)

Secondary cause ?• Ventilation is checked – OK• Cleaning procedures – None• Management/stress - OK• Blood samples from different ages
– Ap6– Mycoplasma hyopneumonia– PRRS– Influenza– PCV2

Lab Answer• Two weeks before Ap6 antibodies there is
a rise in PRRS antibodies (secondary cause)
• Treatment – none• Vaccination of sows
– The PRRS will still be circulating• Vaccination of pigs
– Extremely expensive
