Vetmag Ultra-Fine

VetMag is a ready to use powdered magnesium feed supplement suitable for drenching, pasture spraying and applying to hay or silage.


Magnesium suplementation is usually required in the first 3 months and last 3 weeks of lactation and during periods of cold, wet weather when feed intake may fall. Grass staggers, or hypomagnesia, can occur in early spring during periods of rapid grass growth when lactation demands outstrip magnesium intake.


VetMag is an ultrafine product containing 95 - 97% Magnesium Oxide and a minimum of 57% elemental magnesium.
It has a very low level of heavy metals, and is highly reactive - more so than some other products available on the market.


Mix 1kg VetMag with 3 litres of lukewarm water. Stir and continue stirring until the slurry is of a consistent nature. Heat will be generated, it may even boil, as this is an exothermic reaction due to the high purity and reactivity of VetMag.
