Swine vaccines

Vaccinations are available for a number of diseases that affect swine. In some cases vaccination constitutes the major part of the control of the disease. In many other cases it is only a small part of the control program. Vaccination programs need to be tailored to each swine operation. Remember that vaccination only raises a pig's level of resistance. If other important management procedures are neglected, even this elevated level of resistance may be inadequate to prevent disease. Vaccines must be stored and administered according to label directions if they are to be effective. Slaughter withdrawal time must be observed at all times to avoid illegal residues. The most common times for administering many vaccines are before breeding and before farrowing. This protects the sow and passes antibodies to the piglets for their protection.
