【 摘 要 】

Vaccination was applied in a pig herd using an E2 vaccine candidate against classical swine fever (CSF). The sows received a two-dose vaccination schedule (25 µg) at intervals of 21 days. To evaluate the safety of E2 vaccine candidate in pregnant sows up to the second third of gestation, the reproductive performance of these sows was compared with a group of non-vaccinated sows in the last third of the gestation period. Data about repetitions of zeal, abortions, number of offsprings per litter and pups weaned per breeding by sow were registered. When comparing parameters between groups there were no differences. E2 vaccine candidate against CSF is safe when it is applied to pregnant sows until the second third of pregnancy.
