Too many clinicals

Too many clinical cases of mastitis are costly to the farm business, and disrupt milking.

Why is this important?

  • Too many clinical cases are costly to the farm business, and disrupt milking.
  • High numbers of clinical cases may indicate problems with:
    • Preventing mastitis before calving
    • Preventing mastitis in lactation
    • Missing cases in the colostrum period
    • Treating cases that did not meet the definition of a case requiring treatment.

You have a problem with clinical mastitis if:

  • More than 15 cases/100 cows treated annually - see Industry benchmarks
  • Your herd is performing above trigger on Mastitis Focus Report i.e.
    • Above 8 cases/100 cows calved for monthly clinical case rate at calving
    • Above 16 cases/100 first calvers calved for first calver clinical case rate
    • Above 1 case/100 cows in milk for monthly clinical case rate in lactation (all cows)

Your options include:

  • Work out value of reducing clinical mastitis. Go to SmartSAMM Gap Calculator.
  • Work out when clinical mastitis is affecting your herd. See your Mastitis Focus Report for key areas to focus on.
  • Review prevention systems. See:
  • Review detection systems. Poor detection in colostrum period may mean too many clinical cases in milking herd. See:
  • Review treatment systems. Make sure that cows to be treated meet the definition of a clinical case. See definition in:
  • Guideline 4.2.
