Abstract: China is the largest feed producing and consuming country in the world. The huge production and consumption of feed required a huge amount of raw materials. The problems of supply tightly of feed grain and lack of arable land were highlighted. The total cumulative imports of soybean feed raw materials had reached 96.52 million tons in 2021. Developing forest source feed could partial substitute grain feed, which can effectively solve the contradiction between supply and demand of feed, and promote the high-quality and integrated development among agriculture, forestry and animal husbandry. This paper summarized the preparation and utilization technology of plant protein feed, insect protein feed, functional oligosaccharide feed additive and forest source feed additive of extract in forest feed and additives in China. The bottleneck problems in industrial development were also analyzed, such as low utilization rate of resources, lack of industrial core technology, weak support of science and technology and weak industrial foundation, etc. Finally, in the fields of industrial development planning, scientific and technological innovation system and policy support, policy suggestions were proposed forward to develop Chinese forest sources feed and additives industry.
