Abstract: China has a long coastline and a rich variety of macroalgae,including red seaweeds,brown seaweeds and green seaweeds.The output of macroalgae cultivation in China is about 19.4 million tons,and the main varieties are kelp,wakame,laver,gracilaria and so on.Macroalgae is a kind of sustainable marine resource,rich in nutrients such as protein,fatty acids,minerals,and functional substances including polysaccharides,polyphenols,halogenated compounds,and terpenoids.It is beneficial for ruminant nutrition and physiological health,and is helpful for reducing methane emissions of ruminants and alleviating global warming.Macroalgae has unique advantages of no residue and no biological resistance.Hence,it has great potential in developing green and healthy animal feedstuff.The article reviews the bioactive substances and physiological functions of macroalgae,while combined with their applications in rumen environmental regulation,improving antioxidant and immune properties,enhancing production performance and reducing greenhouse gas emissions of ruminants,in order to provide scientific basis for the development and utilization of macroalgae resources.

Key words: macroalgae; nutritive value; bioactive ingredients; ruminant
