Abstract: China is a big country of agriculture,among which pig breeding is the pillar industry.However,the shortage of feed materials and long-term dependence on imports are the basic status of China's livestock industry.Therefore,to exploit unconventional feed is of great significance for pig breeding.Unconventional feed derived from plants,including Broussonetia papyriferal, Folium mori,Cichorium intybus L.and Medicago sativa have the advantages of high nutritional value and yield,besides,their feature of convenient processing and storage,make them potential to replace conventional feed.Both fresh leaves and dried leaves of Broussonetia papyriferal can be used for pig breeding,and the best additive amount of dried leaves is about 10%.Cichorium intybus L.contains polysaccharides,organic acids,flavonoids and other biological active substances,in addition to its good palatability,it is also a potential feed source in pig breeding.An appropriate amount of Folium mori addition can not only improve the production performance of sows,but also improve the meat quality of fattening pigs.The optimal addition amount of Folium mori powder is 6%-10%,which can be further improved after fermentation.As the "king of herbage",Medicagosativa has the advantages of high protein content and balanced amino acid content,its biological function can be achieved at various growth stages of pigs,including weaned piglets,growing pigs,fattening pigs and pregnant sows.These kinds of unconventional feed have the potential to replace partly of the diet in pig breeding.This paper introduced the application of four kinds of plants derived unconventional feeds from the aspects of nutritional value,feeding method and application status.

Key words: unconventional feed; Broussonetia papyrifera; Cichorium intybus L.; Folium mori; Medicago sativa
