The results of the present study indicate that the probability of reduction in total bacterial
staphylococcal and streptococcal counts could be expected to be greater where a disinfectant is
used prior to milking compared to washing with water treatment. This study shows that the use
of some disinfectant products prior to milking can have beneficial effects on reducing the levels
of total bacterial, staphylococcal and streptococcal pathogens on teat skin. Therefore, the
possibility of bacterial transfer from cow to cow during milking could be expected to be reduced
compared to many farm situations where washing with water is normally practiced.
