  • Nice introduction into mastitis control in practice. Before culturing can be applied, somatic cell count is the first step and one of the most reliable and widely accepted indicators for mastitis (udder health), both for clinical and subclinical cases. Now there is a reliable on-farm Ekomilk cellcounter at 0.04$/test with mastitis monitoring app per quarter, per cow/udder and for the herd. You could also get algorithms to guide you (suggestions) in the decision making for each case. www.ekomilk.eu

How to Control Mastitis and Lower Herd Milk Somatic Cell Count- Larry Fox

  1. 1. How to Control Mastitis and Lower Herd Milk Somatic Cell Count Keys in prevention of mastitis and practices to lower and maintain lowered SCC Larry Fox Professor, Washington State University
  2. 2. Key to Mastitis Prevention • Keep the bugs away from the teats
  3. 3. Boy in the Bubble- David Demaret
  4. 4. Objectives of Discussion • 1) Define mastitis • 2) Describe the mastitis triangle • 3) Discuss host immunity • 4) Discuss the mastitis pathogens • 5) Describe how control over the environment can lead to mastitis abatement.
  5. 5. Mastitis Triangle Mastitis Pathogen Environment Host
  6. 6. How to Decrease Mastitis • Understand: – There are 3 types of mastitis pathogens- – The contagious – The environmental – The opportunists
  7. 7. Mastitis Control- Pathogens • Contagious mastitis- – Chiefly Staphylococcus aureus – Mycoplasma sp. and Streptococcus agalactiae
  8. 8. Mastitis Control- Pathogens • Environmental mastitis- – Coliforms (Escherichia coli & Klebsiella sp.) – Other Streptococci (S. uberis and dysgalactiae)
  9. 9. Mastitis Control- Pathogens • Opportunists- – Coagulase negative staphylococci
  10. 10. Host-Pathogen Interaction • The response
  11. 11. Teat End Anatomy Alveolus
  12. 12. Sentinel for Mastitis • The milk leucocyte (milk somatic cell)
  13. 13. Mastitis Control- Practices • Contagious mastitis • Disinfectant in the wash water or pre- dip – Wash water- 10 ppm iodine – Predip 0.1% iodine, 10,000 ppm – Single Service towels • Cloth vs paper towel
  14. 14. Mastitis Control- Practices • Contagious mastitis • Disposable or rubber gloves • Post dip (1.0% iodine) • Backflush (1 liter/cup, – 100ppm iodine)
  15. 15. Mastitis Control- Practices • Segregation • Culling XX
  16. 16. Mastitis Control- Practices • Environmentals- • Cleanliness • Cleaning rear meter of stall • Clean and dry, dry, dry • Anticipate worst months • Culling?
  17. 17. Mastitis Control- Pathogens • Opportunists- • Obiquitous – Coagulase negative staphylococci – TD/DCT-
  18. 18. Mastitis Control- Practices • Lactating Cow therapy – Necessary but – Reflects the inability to prevent • Dry Cow therapy – Longer acting dose – More potent dose – No milk withhold – Meat withdrawal not a concern
  19. 19. Mastitis Control- Practices • Dry Cow therapy – Longer acting dose – More potent dose – No milk withhold – Meat withdrawal not a concern • Other factors – Teat sealant
  20. 20. Teat Sealant
  21. 21. Mastitis Control- Practices • Dry Cow therapy and Teat Sealant – Bactericidal action of the antibiotic – Internal teat sealant- (bismuth subnitrate) – External teat sealant – Teat sealants as a physical barrier
  22. 22. Mastitis Control- Practices • Opportunists • Milking equipment function • Teat Dip
  23. 23. Relationship between milk leukocyte and milk quality • As leukocytes increase, quality decreases Casein Cheese yield Shelf life Taste
  24. 24. Tissue Damage Result • Change in composition – Influx of salt ions – Decrease in lactose – Decrease in milk protein, casein • Decrease in production
  25. 25. Mastitis Causes •$ • Milk quality and quantity suffer
  26. 26. Objectives of Discussion • 1) Define mastitis • 2) Describe the mastitis triangle • 3) Discuss host immunity • 4) Discuss the mastitis pathogens • 5) Describe how control over the environment can lead to mastitis abatement.
  27. 27. Mastitis Control in a Nutshell • Keep the bugs away from the teats as best as possible • Help the cow achieve maximal immunity • Cow comfort, good nutrition but not immune/mineral/vitamin stimulants
