  Abstract: Abstract Seaweed (known as the marine algae) has a tradition of being part of the animal feed in the coastal areas, from ancient times. Seaweed, are mixed with animal feed, because when consumed alone can have some negative effects on the animal. Seaweed are very rich in useful metabolite (pigments, carotenoids, phlorotannin, polyunsaturated fatty acids, agar, alginate and carrageenan) and minerals (iodine, zinc sodium calcium, magnesium, iron, selenium), being considered as a natural source of additives that can substitute the antibiotic usage in various animals. Inclusion of naturally available material in poultry feed additive can have a positive influence on the poultry performance and enrich the quality of their by product. As an easily available and renewable biomass rich in biologically active compounds, seaweeds can meet this demand. Different forms of seaweed powder from naturally occurring biomass, cultivated or waste biomass, extracted compounds, post extraction residues or liquid extracts may be used in poultry feeding. This study describes the nutritional values of seaweeds and their effects in poultry feed additive, and to what extent their unique properties can serve as an alternative to antibody growth promoter.
