title: Effect of a bioengineered pseudorabies (Aujeszky's disease) vaccine on the semen quality of boars.
abstract: Eight boars 11 months of age that were seronegative to pseudorabies virus were trained for hand collection of semen. A genetically engineered pseudorabies virus vaccine was given to 7 of 8 boars, while the eighth was left unvaccinated to serve as a control. Semen samples were collected at 7 day intervals from 42 days prior to vaccination through 49 days after vaccination. Rectal temperatures and general health of the boars were clinically normal throughout the trial, and no clear differences were observed in the quality of semen collected from the boars before or after vaccination. The semen samples were tested for vaccine virus and none was detected.
