  • Table 30 use of oxytocin, 29% of low count never use while 44% of the highest level never use
  • 65% of the high agree or strongly agree, while only 32% of the lowest agree or strongly agree
  • 6.5 times as many people think that >500,000 is okay are in the highest BTSCC category instead of the lowest
  • P <.0000

    3. 3. Key Findings• Attitude does matter!• “I get concerned if the somatic cell count of my herdreaches…”• “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 (drytreat)– Changing liners more than 5 times per year
