Abstract:

China is the largest potato (Solanum tuberosum) producer in the world, and potato production brings a large number of by-products. With the continuous improvement of the scale of livestock and poultry farming in China, the demands for feed raw materials are increasingly growing. Potato by-products are rich in crude fiber, crude fat and amino acids, and contain certain amount of minerals. As an unconventional roughage for ruminants, they have gradually received concerns. However, due to the lagging development and utilization technology of potato by-products, their feeding value and utilization rate are still limited. Therefore, how to improve the utilization rate of potato by-products and give full play to their feeding and nutritional value are urgent problems to be solved. In this paper, the research progress in forage utilization of potato by-products, such as potato straw, potato residue, potato starch residue and starch, and potato protein are reviewed, in hoping to provide references for the further study on forage utilization of potato by-products.

Key words: potato by-products, roughage, feeding value, forage utilization
