The basic vaccinations for feeder pigs are atrophic rhinitis (bordetella), actinoba- cillus pleuropneumoniae (APP), mycoplasmal pneumonia, and erysipelas. Vaccines contain “safe” microorgan- isms that are injected into a pig to prepare its immune system to resist diseases.
Most veterinarians agree that at minimum, pet piglets should be vaccinated against the bacteria that cause the infections erysipelas, leptospirosis, and tetanus.
The best time to vaccinate small pigs is around weaning time, as they are individually handled regularly. This is usually around 3 to 6 weeks of age.
Vaccines are available for leptospirosis, erysipelas, porcine parvovirus, E. coli scours, mycoplasma pneumonia (also known as enzootic pneumonia), actinobacillosis pleuropneumonia (APP), Glässer's disease (Haemophilus parasuis), and ileitis (Lawsonia intracellularis)
