Compared with the basic nutrition, functional feed is a kind of new health care feed which contains functional ingredients, and can promote the growth of animal health, enhance immunity, improve the quality of animal products, improve the level of ani- mal welfare, reduce environmental pollution, improve the ecological environment, as well as increase the economic benefits. Studies on the functional feed are mainly concentrated in the development of functional feed products, and but few to under- stand the compositions and compatibility mechanism of the functional components that have the function effects. Moreover, these functional components are low in plants, so the wide application in feed industry requires research on biological engi- neering and chemical synthesis, which will become the trend of future research.展开更多
