Abstract: Cassava residue is a by??product produced in the process of cassava processing starch or alcohol，which rich in nutritional ingredients，such as starch and cellulose. The cassava residue is easy to produce mildew and cause waste and pollution of resources. The poor palatability of high fiber and the existence of anti-nutritional factors limit its application in feed. Fermentation can increase the nutritional composition and palatability of cassava residue. Fermented cassava residue can be used as a feed material in livestock and poultry production to animal production，reduce breeding costs，and realize resource utilization and reduce environmental pollution. In this paper，the improvement of nutritional value of cassava residue by fermentation and its application in livestock and poultry production were reviewed，providing theoretical basis for for further research and utilization of fermented cassava residue.
