Seaweeds are large algae that grow in a saltwater or marine environment. There are over 400 species of seaweeds in the bay of Korea. Most seaweeds are divided into three groups according to their color ; the green seaweeds(division Chlorophyta), the brown(Phaeophyta) and the red(Rhodophyta). Seaweeds have been harvested for use as food, fertilizer, animal feed and medicines for thousands years. In the past decade, there has been increasing interest in using seaweeds for animal feedstuffs and feed supplements as their health qualities are becoming better known. In this review some perspectives on nutritional values and the role of functionality ingredients of various seaweeds will be also discussed.
Ecklonia cava kjellman(EC), a perennial seaweed, is one of the main components of the marine forests along the East and South coasts of Korea. We conducted three experiments to evaluate the nutritional values of EC and the crude lectin extracted residues from EC(LEEC) and to investigate their dietary effects on productivity and immunocompetence in poultry. The crude protein content of EC was relatively low(about 10 %) and its amino acids were poorly available. But. the results of our study suggested that EC can be used into broiler feed up to 3 % without any adverse effect, if its nutritional values are well evaluated prior to use. Similar results of dietary LECC up to 1.0 % level on egg production and egg quality have been obtained in layers. The concentrations of serum TNF-α after Salmonella challenge were rapidly increased in accordance with the level of LEEC. These results indicated that LEEC can be used as a feed additives for enhancing of immunocompetence in poultry.
