Abstract:

Seaweed is a general name for algae in the ocean.It is distributed in the shallow sea area below the low tide line and is an occult plant in the plant kingdom.There are more than 30 000 species of algae known worldwide.Algae that have been developed and utilized by humans are mainly divided into four categories:Red algae,brown algae,green algae,and cyanobacteria.With the tight supply of conventional feed ingredients and rising prices,the development of unconventional and integrated functional feed has become a long-term task to solve the effective supply of feed resources in the livestock industry.As a high-quality unconventional feed resource,seaweed has the characteristics of wide distribution,large yield,strong adaptability,etc.,and contains a large number of biologically active substances and nutrients that terrestrial plants lack,and these characteristics determine its enormous value in feed economic development.The authors reviewed the regional distribution,characteristics,classification and functions of various nutrients and their applications in animals of seaweed.Seaweed is rich in nutrients such as proteins,amino acids,minerals,polyunsaturated fatty acids,and functional substances such as polysaccharide polyphenols and terpenoids.The authors also pointed out that seaweed has great development potential in animal husbandry production and application,as well as the problems that should be paid attention to the process of using seaweed as feed ingredients,and explore its application value and potential market in multiple functional fields of animal production.This review was respected to provide a reference for the application of algae resources in animal diets.
