Hypomagnesemia

  • Cattle generally supplemented with Magnesium pre calving to prevent metabolic disease (eg milk fever and grass staggers)
  • DairyNZ advice is 12-20g Mg to be supplemented to dairy cows each day, from 2-3 weeks pre calving until after peak lactation
    • –In NZ this means Mg supplementation occurs end June to November
  • BeefNZ also recommend supplementing Mg as up to 20% mortality has been recorded from hypomagnesaemia (Morris 2009)
  • Methods of Magnesium supplementation include:
    • –Mg Oxide top dressed on pasture, or added to silage & other feeds
      • drenching / molasses/ licks / & ‘fortified’ compound feed less commonly used
    • –Mg Sulphate/Chloride added to water trough system or feed (mainly dairy, as beef farms often lack water reticulation infrastructure)
    • –Mg Capsules
      • especially extensively grazed beef cows, where pasture dusting is impractical
