Phagocytes at work:
• A phagocyte attacks a bacterium and destroys it
• Important information required for the animal to express the appropriate immunological response is collected by the phagocyte
• The correct active immune response is induced
Phagocyte = a macrophage attacks bacteria
Viral protection of sows and their foetuses against PRR-virus, Circovirus and Parvovirus inside the uterus.
A single vaccination of gilts against PRRS is insufficient for optimal protection. When facing PRRS-outbreaks, a stable herd immunity can only be achieved by total herd vaccination. Well tolerated sow vaccines allow vaccination of gestating sows during every stage of pregnancy.
Behavioural studies show: Differences in suckling-activity of piglets and/or feed intake after vaccination can be explained largely by the tolerance or intolerance of piglets to the vaccines applied.
