Ø-VET

Where• Oe-Vet

– Private Company– 7 veterinarians– Consulting 400 herds– Eastern Denmark– Also Slovakia,

Russia, Ukraine, Lithuania.

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

• 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%

• 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.

• 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

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

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

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.
