Minimizing Your Chance of Milk Fever - What We Know

  • Springer cows benefit from 3 weeks of preferential treatment prior to calving. In that time:

    • Avoid effluent paddocks (High potassium prior to calving = Milk Fever)

    • Ensure springers receive sufficient (but not too much) Magnesium daily

      • Through water, feed, or dusted are options

      • If you are unsure check with us

    • Ensure springers receive sufficient (up to 12 Kg DM for big girls!) feed and NOT TOO MUCH fresh / leafy grass. Ideal diets include:

      • ~ 50% Pasture (Mature / stalky pasture)

      • ~ 25% Hay / poor quality silage

      • ~ 25% Meal or Maize Silage

    • Additional Calcium pre calving is OK providing you use:

      • Gypsum (Calcium Sulphate)

      • DCP/ MCP (Dicalcium Phosphate or Monocalcium Phosphate)

    • Use of ‘Ionophores’ is recommended – e.g Rumenox

  • Often Milk Fever becomes more of an issue several weeks into calving as farmers become distracted with the day-to-day operation of the farm AND springers having access to faster growing ‘leafy’ pastures, so remain vigilant as you progress through calving

  • Remember – Milk Fever is a ‘gateway’ disease – responsible for many other expensive animal health issues around calving.
