Outline
1. Key findings2. Survey methodology3. Descriptive statistics4. Key variables: bivariate findings5. Key variables: multivariate findings
Key Findings
• Attitude does matter!• “I get concerned if the somatic cell count of my herd
reaches…”• “Mastitis is a problem on my farm”
• Key practices:– Use of oxytocin for milk letdown– Use internal teat sealant at dry off– Use intramammary antibiotics at dry off (dry treat)– Changing liners more than 5 times per year

Recommendations
• Back the basics
• Attitudes: lower acceptable threshold
• Practices:– Use of oxytocin during milking– Use internal teat sealant at dry off– Use intramammary antibiotics at dry off (dry treat)– Changing liners more than 5 times per year
Next Steps
• Sub-group analysis
• Employee practices
