    Abstract / Zusammenfassung

    A field trial was conducted to evaluate long term and seasonal effects on the development of microbiological colonization in a newly installed milking parlor. The milking equipment was a 2 x 34 side-by-side milking parlorin a commercial dairy herd in Germany. The 1st batch of samples was taken before beginning of milking and in weekly intervals for a period of two months in winter 2002. The 2nd batch of samples was collected in summer 2003. After sampling the diagnostic material was kept in Amies medium at 4 °C until analysis. Samples were analyzed from the mouthpiece, the shank of the liner and the flushing adapter. The samples were collected immediately after disinfection of the milking equipment. They were analyzed qualitatively and quantitatively according to the official German guidelines (Amtliche Sammlung von Untersuchungsverfahren, Β35, LMBG). Mesophil aerobe total plate count, S. aureus, E. coli, Coliforms, Streptococci, Yeast and Lactobacilli were considered. Results indicate a relationship of microbiological colonization of the surface of the milking technique with season and location of sampling. The microbiological colonization was higher in summer than in winter. There were more mesophil aerobe pathogens on the flushing adapters than on mouthpiece and shank of the liner.
