Förekomsten av PDS i den europeiska grisproduktionen

Abstract: The purpose of this literature review is to study differences in the occurrence of postpartum dysgalactia syndrome (PDS) between some European countries and to summarize some of the most common signs. It is important to detect signs of PDS at an early stage to be able to undertake appropriate actions. An elevated body temperature and mastitis are two common signs where a threshold temperature of 39.5°C to 40.0°C is commonly used. However, body temperatures have a circadian rhythm and the time of measurement affects the temperature recorded. Coliform bacteria, predominantly Escherichia (E.) coli, were detected in both healthy animals and individuals diagnosed with mastitis and PDS. No difference has been shown in the number of bacterial species found, nor has any specific strain of E.coli been isolated. Possibly, the individual immune system together with factors in the local environment and genetic factors has impacts on the incidence of mastitis and PDS. In one of the largest pig-producing countries, Germany, only four studies that describe the presence of the PDS have been found in the literature. These four studies only comprised 10 farms and from these limited studies, no conclusions can be made on the prevalence in Germany. Further, no conclusion can be drawn about the existence of the PDS in the EU from this literature review since only eight studies from four countries were available.
