Abstract Background The performance of piglet weight gain is strongly dependent on the sow s ability to meet the demand for adequate milk. Postparturient disorders especially those subsumed under the term postpartum dysgalactia syndrome PPDS can alter or reduce the milk production sensitively resulting in starving piglets. The aim of this study was to gather further information about the prevalence of different bacterial species in the anterior and posterior mammary glands of sows with respect to the clinical appearance of PPDS. Methods In this study the health status of 56 sows after farrowing was determined with special regard to mastitis and dysgalactia. Pooled milk samples from anterior and posterior glands were taken from both affected and non-affected animals and analysed bacteriologically for the presence of a wide spectrum of different pathogens. Results Mainly Escherichia coli staphylococci and streptococci were detected in high percentages but without significant .
