Introduction

  • With chronic recurrent cases of clinical mastitis and chronic high cell count quarters, often the best time to effect a cure is during the dry period.
  • However, often only one quarter is problematic and so it may be appropriate to only dry off the affected quarter. Individual quarter dry off should be considered for unresponsive/persistent single quarter infections.
  • This allows the cow can to continue being milked on three quarters.
    • Whilst there are obvious disadvantages to having three quartered cows in the herd, if the alternative to drying off a quarter is to cull the cow (a very expensive option!), then often a three quartered cow may be acceptable.
However, bear in mind that this single-quarter drying off approach is not a sustainable solution. If a large number of cows are being selected for single quarter drying off then the rate of NEW cases is likely to be high Mastitis: approach to the herd mastitis problem.
