Development of a screening tool for the monitoring of contagious mastitis pathogens in dairy herds using automated milking systems (OG Masti-Screen)
A mastitis screening tool for the detection of intramammary infections with contagious mastitis pathogens was developed for dairy herds using automated milking systems (AMS). As inflammation or an increase of somatic cell count is frequently missed in subclinical infections, detection of the infectious agent itself is the only reliable method for early diagnosis. To establish an early warning system, PCR methods were applied for samples collected automatically in herd improvement programmes (e. g. milk yield recording). To identify samples suitable for the systematic screening of cows with a higher mastitis risk in AMS herds, colostrum was tested by bacterial cultivation. During the last stage of the project, the early warning system and the monitoring of cows at high risk for mastitis were established in AMS herds to improve their udder health.
The aim of the project was to develop a monitoring system based on the results of the first two work packages (suitability of the PCR method, suitability of colostrum samples), which was to be tested for mastitis monitoring on farms with AMS. Work package 1 showed that the use of the PCR method could not be recommended for samples from the milk performance test. For this reason, no more samples were tested using PCR in the third work package (aim of the project). Colostrum samples are well suited as a component of mastitis monitoring regardless of the existing milking system. This was reported back by farms, to use these as sample material for S. aureus remediation. For the laboratory of the "Veterinary Health Service", this is an extension of the diagnostic spectrum of mastitis testing.
