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.
Inflammation of specific udder segments can occur at any stage during the lactation.
When milk-release is impaired by mastitis in one or more udder segments, there is the threat that FIL (a protein) will be released: when the concentration of this protein in the udder milk in creases, milk production is suppressed and eventually milk flow will stop.

The highest level of reproductive performance will be found on farms where feed intake is adjusted to the need of each individual sow. For this reason it is necessary to have a farm-specific feeding regime where the body condition of each individual sow pre-farrowing is documented and feeding adjusted accordingly on a sow by sow basis.
