How do you Measure success regarding milk quality? Check out these key performance indicators for microbial quality bulk milk to see how your farm is performing.
Key performance indicators and sources of typical bacteria used to troubleshoot problems with bacteriological quality of raw bulk milk.
Standard Plate Count
Laboratory pasteurized count
Preliminary incubated count
Types of Bacteria Detected
Quantifies most viable, aerobic bacteria found in milk
Theromduric bacteria (such as bacillus, clostridia etc.)
Psychotrophs (such as pseudomonas and others)
Colifrom bacteria (such as E. coli and Klebsiella)
Contamination during milking; problems with milk cooling; cleaning failures
Biofilm development on milking equipment as a result of cleaning failures; occasional problems with contamination
Contamination during milking; cooling problems
Contamination during milking, rarely mastitis
|Other key performance indicators include:
• Qualitative bulk milk cultures
• Milking systems & performance
• Subclinical mastitisUW-Milk Quality promotes an integrated, team-based approach to best manage udder health and milk quality. Producing high quality milk is not a one-person job. It takes farmers and their local dairy advisors to be able to evaluate, manage and improve milk quality.At UW-Milk Quality, we develop tools and resources to help dairy producers meet their milk quality goals and increase farm profitability.For more information regarding milk quality, please visit UW-Milk Quality or contact UW-Extension Milk Quality Specialist Pam Ruegg. For more information regarding milking systems, please visit UW Milking Research and Instruction Laboratory or contact UW-Extension Milking Systems Specialist Doug Reinemann
