King Island Organic Kelp Meal is a general purpose kelp supplement, a natural, balanced source of vitamins and minerals. It contains over 50 different elements and used for centuries as a supplement in animal/stock feeds. Dried and then pulverized to produce an easy to use, granulare type preparation for addition to animal rations. It is recommended by farmers, stock breeders and equestrians.

Studies carried out on the use of seaweed as part of the food ration in livestock have established that it provided significant benefit to animal health by the provision of minerals, vitamins, alginate and osmoregulatory compounds called betaines, that enhance beneficial gut bacteria so that food nutrients are readily absorbed and better utilized.


The benefits of kelp meal

  • Reduce incidence of loss of body weight (cobalt)
  • Boost resistance to parasites and diseases (cobalt, copper and zinc)
  • Reduce scouring and dehydration (cobalt & copper)
  • Boost general health promoting healthy eyes, teeth, and coat (cobalt, copper and zinc)
  • Reduce finishing times

Tasmanian bull kelp grows in arguably the cleanest waters in the world, and there are no concerns over heavy metal contamination by cadmium or mercury. Seaweed is regularly fed to horse in Europe, the UK, USA, and New Zealand. While the seaweeds used are different (although they are still brown seaweeds) Australian bull kelp has shown to give equivalent results.
