At what age should vaccinations for Erysipelas be initiated for gilts or boars?

Vaccinations for Erysipelas should be initiated for gilts or boars at 6.5 months of age or older because this timing allows for the immune system to be sufficiently developed to respond effectively to the vaccine. Erysipelas, caused by the bacterium Erysipelothrix rhusiopathiae, can lead to significant health issues, including skin lesions, arthritis, and reproductive problems in swine. By vaccinating at this age, producers help ensure that the animals have built up sufficient immunity before they may come into contact with the pathogen, which is especially important as they near the stress of breeding and higher animal density environments.

Starting vaccinations too early might not provide adequate protection, as younger animals’ immune systems may not respond as robustly to the vaccine. That’s why the guidelines recommend this specific age range to optimize health outcomes and production efficiency.
