    Abstract / Zusammenfassung

    The association of milking practices with DHI somatic cell counts (DHI-SCC)
    was studied on 80 large dairy farms in Brandenburg, Germany, in 2002 and
    2003. All farms were visited by the same veterinarian and milking practices
    were recorded using a standardized record sheet. To reduce the number of
    individual items in the analysis these were reduced to compound variables using
    factor analysis. The association of the milking practices with DHI-SCC was
    analysed for the current month and the average DHI-SCC of the last year.
    Factor analysis for factors associated with milking management and routines
    derived three major components that combined two or three factors each. The
    first component was use of water in the milking parlor for udder and teat
    cleaning and cleaning of the parlor between cows. The second was attention of
    the milkers (detection of mastitis, reliability of teat dipping, use of cluster
    disinfection) and the third was udder preparation (material used for teat
    cleaning, forestripping). The range of values derived from the factor analysis
    was categorized into three classes, representing one third of the range each with
    low values being good and high values being had.
    Good values for use of water in the parlor were associated with lower DHI-SCC
    both for the current month and the last year than had values (P=0.019 and 0.003,
    respectively). Attentive, keen milkers were associated with lower DHI-SCC than
    milkers that were less attentive (P=0.014 and 0.012 for the current month and
    the last year, respectively). In contrast, the component including material used
    for teat cleaning and method of forestripping was not significantly associated
    with SCC.
    Results of the study indicate that it is crucial to sensitize milkers for the
    importance of proper milking routines and to remind them of their vital role for
    the udder health of a dairy herd.
