Seaweed Meal Food Supplement

The Kelp Solution
Modern intensive farming practices have resulted in soils with deficiencies that are reflected in the low nutritional content of grasses and grains grown on these soils, and in the health of animals raised and maintained on these crops. Lush and otherwise nutritious grasses may fail to supply the needs of animals because certain trace elements are missing. Animals have finely balanced needs for trace elements; too little produces deficiency symptoms, too much may be toxic.

The problem associated with oversupplying trace elements can be avoided by using kelp as the source because it provides trace elements in a naturally balanced form.

Kelp as a Feed Supplement
Ascophyllum nodosum seaweed has been used for centuries as a natural source feed supplement. Today, thanks to modern processing technology, the benefits of ascophyllum nodosum seaweed are available in cost-effective dried granular form which can be conveniently added into the regular feeding programme.

Commonly known as Norwegian Kelp or Rockweed, ascophyllum nodosum seaweed is widely recognised to be the richest marine plant for agricultural use. This unique seaweed grows exclusively on the North Atlantic coasts of North America and Europe, and is particularly abundant on the North Atlantic coast of Canada.

Ascophyllum nodosum contains over 60 minerals and elements, more than 12 vitamins, including carotene, tocopherol and folic acid; valuable carbohydrates including alginic acid, laminarin and mannitol, as well as a full range of amino acids.

Benefits of Seaweed Meal
The regular use of Seaweed meal as a supplement helps increase the utilisation of all the ingredients in the complete feed ration, improving the overall health and performance of animals.

Observations by farmers and breeders, as well as controlled testing, indicate the following benefits from feeding Seaweed meal:

Dairy and Beef Cows

  • more efficient feed utilisation
  • increases regularity of heat cycles
  • improves conception rate
  • fewer problems caused by dietary deficiencies such as mastitis, retained
  • placenta, milk fever, abortions and infertility.

    Dairy Cattle

  • increases milk yield
  • increases butterfat content in milk
  • increases iodine and vitamin A content in milk
  • minimises production losses during stress periods
  • prolongs lactation periods

    Beef Cattle

  • improves weight gains and feed efficiency
  • increases loin size
  • reduces back fat


  • improves weight gains and feed efficiency
  • reduces mortality
  • better feathering
  • increases pigmentation

    Poultry-Layers and Breeders

  • increases hatchability of eggs
  • reduces blood spots
  • increases iodine content of eggs
  • increases yolk pigmentation
  • more uniform shell texture with reduced breakage
  • increased laying period in older hens

    Poultry - Turkeys

  • improves weight gains and feed efficiency
  • increases hatchability of eggs


  • rapid gains for earlier marketing
  • increases loin length and size
  • larger loin eyes
  • reduces back fat
  • reduces internal parasites
  • increases litter size


  • increases birth rate
  • easier lambing
  • better quality wool


  • increases birth rate
  • improves weight gains and feed efficiency
  • increases milk yield for dairy goats


  • increases fertility in brood mares
  • reduces incidents of cracked hooves
  • minimises stable vices and nervous habits
  • increases resistance to infection and reduces healing time for injuries

    Shrimp and Prawns

  • increases weight gains
  • reduces susceptibility to disease

    Seaweed meal can be mixed directly when the feed is ground and blended. When direct mixing is not possible, top dressing Seaweed meal onto the feed is recommended. Seaweed meal is usually mixed with complete rations at 1-2.5% of the total diet.
