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. Key to Mastitis Prevention
• Keep the bugs away from the teats
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.
17. 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
28. Tissue Damage Result
• Change in composition
– Influx of salt ions
– Decrease in lactose
– Decrease in milk protein,
casein
• Decrease in production
30. Objectives of Discussion

31. 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
