Abstract

A fully age-structured deterministic model of the population biology of a pseudorabies epizootic in a farrow-to-finish operation was used to examine the disease-related change in productivity following the initial disease episode. A strategy involving continual sow vaccination was compared with various strategies involving the vaccination of growing pigs, as well as sows. The model suggests that vaccinating growing pigs, in addition to the breeding herd, results in only a relatively small improvement in long-term productivity following a pseudorabies epizootic.
