EFFECT OF VACCINATION AGAINST POST-WEANING OEDEMA DISEASE ON PIGLET PERFORMANCE
D. Bor and G. Bilkei

Abstract
In order to study the effect of vaccination against post-weaning oedema disease, a trial was performed on a large East-European pig farm. The unit has a history of oedema disease caused losses. The trial animals were either vaccinated (group one, n=711) with a VT2e-toxoid vaccine at 1 week of age (with 12.5 g inactivated VT2e toxin per pig), and at 3 weeks of age (with 25 g inactivated VT2e toxin), or were placebo treated (group two, n=709). The piglets' post-weaning performance and serological status against VT2e toxin were evaluated.
???? Vaccination significantly (P<0.05) affected average daily nursery weight gains (group 1: 309+/-39g; group 2: 270+/-40g). Mortality due to oedema disease revealed highly significant (P<0.01) differences between the vaccinated (group 1:6 animals=0.8%) and non-vaccinated pigs (group 2:48 piglets=6.8%). The vaccinated pigs showed significantly (P<0.01) higher seropositivity to VT2e.
