Don’t vaccinate pigs too early
- While the advice below is generally applicable there may be exceptions, particularly for vaccines that are not delivered intramuscularly.
- Avoid vaccination during the first 10 days of life*: Energy-intake may be impaired because pigs that are vaccinated need more time before they resume sucking the sow again.
- Smaller piglets have less energy reserves than their larger and stronger littermates and may be even more compromised
- The immune system of young piglets is not yet completely developed
- A stable body temperature is only achieved after 10 days of age: higher risk of hypothermia during and after treatments (Sign: huddling)
- Stronger adverse reactions to vaccinations in young pigs and susceptible litters may occur (i.e. vomiting, huddling, oedema at the site of injection)
Vomiting is a known adverse reaction to injections in very young pigs
*Exception to the rule: vaccination against oedema disease may be required earlier. Follow veterinary advice of your herd vet
