1. Vets and Vaccines Andreas Birch DVM Ø-VET

2. Where • Oe-Vet • Private Company • 7 veterinarians • Consulting 400 herds • Eastern Denmark • Also Slovakia, Russia, Ukraine, Lithuania.

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

4. The Danish veterinarian • Education: • 3 years at gymnasium • 5,5 years at university (Human medicine 6yrs, Dentists 5yrs, Biologists, engineers… 5yrs) • Work: • Government 30% • Meat organization (Danish crown, SPF …) 10% • Private companies 30% • Medical Industry 20% • Other 10%

5. The private swine veterinarian • Farmer is responsible for health • Vet. is advisor in health and diseases • Vets. does not treat animals themselves • Visit all farms minimum 12 times every year • Farmer also calls when he has problems • Working with diseases, feeding, management, housing, breeding etc.

6. 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

7. 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

8. 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%

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

10. 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

11. 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

12. 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)

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

14. 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

15. Sectioning ! 4 sections with 250 pigs and all in – all out followed by total cleaning and disinfection. The cost is earned back in maybe 2 years.
