Bulk tank cultures analyze the level of contagious pathogens including Staph aureus, Strep agalactiae and Mycoplasma species and environmental pathogens including Strep species, Staph species and coliforms.  These levels are reported to the producer in a report that can be used to determine the primary cause and source of mastitis infections

AgSource encourages producers to submit bulk tank cultures comprised of milk samples taken over three days.  The samples are cultured in the lab for 3 to 5 days, and once the analysis is complete, the report can be mailed, faxed or emailed to the producers and their key consultants providing quick and convenient information.  While there are no firm guidelines for bulk tank culturing frequency, quarterly to monthly cultures are recommended depending on management techniques, risk factors and herd size.

By identifying the major mastitis-causing pathogens, dairy producers can implement effective treatment protocols and preventative measures to monitor and improve the quality of the milk produced.
