Mastitis: cost effectiveness for intervention strategies

Introduction

  • Mastitis remains one of the most common diseases of dairy cows and represents a large economic loss to the industry as well as a considerable welfare issue to the cows affected.
  • Decisions are routinely made about the treatment and control of mastitis despite evidence being sparse regarding the likely consequences in terms of clinical efficacy and return on investment.
  • With limited resources available to a commercial dairy farm, it is important that potential mastitis interventions are prioritized not only according to their efficacy, but also on the likely return on investment.
  • The efficient use of available resources requires an understanding of the opportunity costs whereby resources are allocated to fund one intervention at the expense of the potential ‘benefits’ afforded by an alternative intervention.
  • This is the dilemma faced by veterinary decision makers, and with many possible mastitis interventions making claims on farm resources, it is necessary when deciding whether to employ resources in one area to be able to compare the probability of a net benefit in that area with all other potential areas where those resources could be employed.
