  • 1. IMPROVE YOUR COWS’ LIFE TIME PRODUCTIVITY Mastitis is ranked second after infertility as a main reason for culling cows. 20–50% of dairy cows are treated for infection in Europe and the USA “Mastitis greatly affects productivity and is the largest health cost on most farms” 1
  • 2. MASTITIS IS NOT ALWAYS VISIBLE Acute (visible) mastitis can best be described as the tip of the iceberg. The red cow may be the one that’s been detected as a mastitis cow, but underneath are several subclinically infected cows 2
  • 3. Clinical Mastitis Sub-clinical Mastitis VISIBLE SIGNS: Mild Mastitis: Cloggy milk Moderate Mastitis: Swollen udder Severe Mastitis: Loss of apetite/fever NO VISIBLE SIGNS: Milk looks OK Udder looks OK Cow behaves normally But the cow might still be infected which affects milk quality There are excellent tools to pinpoint cases of mastitis 80% of mastitis cases can be detected before they are visible 3
  • 4. HOW TO PREVENT MASTITIS Carry out an annual inspection and servicing of milking equipment “The key to prevention is to reduce the number of bacteria to which my teat ends are exposed” Maintain good hygiene during milking Disinfect all teats after every milking Keep equipment clean and functional 4
  • 5. Environments hould be as clean and dry as possible Exchange bedding material every 48h Don’t overstock the barn Turn bedding material several times a day to keep it dry 5
  • 6. Provide nutritious and healthy feed Treat new and severe clinical cases of mastitis promptly and record data Choose appropriate cases for treatment About 60% of all new infections occur in the dry period, either in the first 21 days after the end of lactation or around calving 6
  • 7. Separate healthy cows from infected ones Eventually cull infected cows when you have replacement 7
  • 8. RESISTANCE TO ANTIBIOTICS IS A PROBLEM The solution is not to increase the level of treatment but rather reduce the need for antibiotics by closely monitoring cell count Antibiotic treatment of mastitis is very costly and creates a lot of waste milk Increase efforts to identify the chronic cases of mastitis This will save time and money and will ensure better milk quality Optimise use of antibiotics. Carefully select your treatment cases “I don’t want to be fed with antibiotics if I don’t need them” 8
