Animal feed ingredients

We are experiencing increasing interest in our human nutrition research and data for animal health. Seagreens® produces seaweed to independently certified quality standards and we have unrivalled expertise in the wild Wrack seaweeds which have long been used at the basic level as an animal feedstuff.

Today we know a great deal more about these seaweeds and their applications, and whether for livestock, valuable performance animals, or domestic pets, the broad balance of nutrients provides a firm foundation for animal health as it does in the human diet.

We have achieved long term consistency in increasing the levels of polyphenols, antioxidants, and essential fatty acids, and the abundance of minerals and trace elements in seaweed responds rapidly and permanently to deficiencies in field and forage and fashion trends in feed formulation.

Seagreens® produced wild seaweeds contain no dead, stormcast, or mixed species, and are human food safe, non-allergenic, and free from harmful any contaminants and microbial pathogens.

Unlike much of the seaweed sold into agri and feed markets, we do not collect seaweeds from beaches or shorelines. Stock product is available as fine, medium and large dried, granulated seaweeed across five different species with varying nutritional profiles.

For everyday inclusion in feed and water, we produce Seagreens® Mineralizing Meal, organic fresh dried 100% raw seaweed between 300µm (microns) and 3.5mm (millimetres) which is popular with biodynamic and organic farms.

All Seagreens products including Mineralizing Meal are certified to the Nutritious Food Seaweed standard - the world's highest standard for human consumption.

“The ‘fertility vitamin’ E tocopherol, varies from 156-298 mg/kg in wild Wrack seaweed (Ascophyllum nodosum), against 25-30 mg/kg in common Kelp (Laminaria) and 111 mg/kg in grass”
- W. A. Stephenson, Seaweed in Agriculture and Horticulture, 3rd edition, Rateaver, California 1974.

Please ask for more information and data.

The granules can be fed direct to the animal as they are, mixed with a premix, directly into the feed, or in drinking water.

In horticulture there are numerous applications in composting, seed soaking, digging in, and for watering and irrigation.

Tom Ventham at Old Plaw Hatch Farm (click to read his comments) a certified Biodynamic teaching farm near Emerson College in Sussex, feeds Seagreens® Mineralizing Meal to a biodynamic dairy herd producing award-winning unpasteurised milk and cheese products.

In Bedfordshire, Nick Griffiths fed Seagreens® to his 450 head of water buffalo before the herd was sold to Laverstoke Park in Hampshire where the milk is now sold in British supermarkets. In 2006 Nick developed leukemia, but after a year on a natural diet and nutritional supplementation including 6 daily Seagreens® Food Capsules, he was pronounced 'all clear' with complete remission.

We remain in touch with Nick and his health practitioner wife Emma on the old farm in Bedfordshire, where they now run a health clinic which also retails Seagreens Food Capsules.

“Seaweed has a composition very different to that of land vegetation...more than 60 microminerals and trace elements varying from 15-25% of the dry weight compared with 5-6% in hay and 4% or less in various grains. The fat and protein is about the same as for vegetation generally, but the vitamin content is exceptionally favourable, with for example, provitamin A (carotene), vitamin B1 (thiamine), vitamin E, folic and folinic acid, and vitamin B12 which does not occur in land vegetation. Seaweed is rich in carbohydrates, but these differ greatly from those found in land plants, with alginic acid, laminarin, and mannitol among the most significant” - T. L. Senn and A. R. Kingman, Seaweed Research Review, 1963.

"Since December 2009 I started giving my little Norwich Terrier, Freddie, the Pet Granules (Seagreens® Ascophylum Granules). I bought him as a 7 month puppy from a reputable breeder, but unfortunately at a year old he showed symptons of demodectic mange. January 2009 I took him to the University of Cambridge Queen's Veterinary Hospital where they confirmed his condition and told me that puppies get this from suckling from their mother who carries the condition. After putting him through 3 lots of complete shaves to enable the vets to treat his skin it was not until September 2009 that the vets eventually considered the mites were dead. At that time I was not aware of the Pet Granules, although I am a long term advocate of Seagreens for myself. I had tried everything for his immune system, even importing powders from the USA. In December 2009 I was ready to order some capsules for myself and noticed a leaflet in my file with the article on Pet Granules, and knew that I should try them for Freddie. The results in the last 3 months have been phenomenal! He is bright eyed, lively, and eating well. I am convinced his immune system has improved since taking the Granules, and congratulate you for producing them. I have recommended them to my local vet" - Maggie Perkins, Peterborough, March 2010.
