Seaweed use in animal nutrition

Algae contain high protein contents with similar essential amino acid profiles to those of soybeans. They also contain significant fatty acids and are important sources of minerals, vitamins and pigments. Which makes them an interesting feed supplement for production animals.

Seaweed use in animal nutrition

Seaweed or marine algae belong to a large group of autotrophic organisms. They can be unicellular (microalgae or phytoplankton) or multicellular (macroalgae) with sizes ranging from 0.2-2.0 microns up to 60 m, respectively. Their reproduction occurs through simple division and due to the simplicity of their structure, they tend to grow faster than any other plant. Therefore, they are characterized as the most productive plants on the planet (Marsall, 2007):

  • Compared to traditional oilseeds, algae can produce five times more biomass per hectare.

There are about 320,500 species of algae.The amount of cultivated or native macroalgae used in industry during recent years rounds up to nearly 7.5-8 million tons per year (Becker, 2007).

Nutritional composition of algae

The nutritional value of algae depends on their size, digestibility, presence of toxic substances and chemical composition (Becker, 1994).

Algae are a remarkable source of protein, with a content of 10-15% in macro-algae (Oliveira et al., 2009) and 28-71% in microalgae. In addition, the content of certain amino acids such as lysine, methionine, tryptophan, threonine, valine, histidine and isoleucine is comparable to that of eggs or soybean seeds.
