The silage is made from green feed fermented by anaerobic microorganisms,which can effectively improve the nutritional structure,prolong the storage time of green feed,and solve the problem of the lack of green feed resources for animals in winter and spring.Fermentation microorganisms,raw materials,fermentation conditions,and additives are the main factors affecting the quality of silages.Based on this,the nutritional value of silages,the factors affecting silage quality,and the application of silages in livestock production are reviewed in this paper to provide theoretical references for fur...
