Development trend of feed industry
(1) Large-scale breeding to enhance the demand for feed additives.
Since August 2018, natural disasters such as African classical swine fever have occurred in various parts of China, and small and medium-sized farmers have been withdrawing from the market. Listed companies in the domestic pig industry chain, such as muyuan shares, new hope, Dabeinong and aonong, are constantly expanding their production capacity, seizing market share, and promoting the process of large-scale pig breeding and the improvement of industry concentration. Large-scale breeding enterprises pay more attention to the comprehensive benefits of animal production, and feed additives can effectively increase feed intake, improve feed utilization, and reduce disease rates. Therefore, the demand for feed additives in large-scale breeding enterprises is more obvious. In the future, with the continuous improvement of the scale of China's aquaculture industry, the demand for feed additives will further increase.

(2) feed additives to "green, efficient and safe" transformation, "for the resistance" to become the inevitable choice of green development of aquaculture
At present, China's feed additive industry is vigorously promoting the product concept of "green, efficient and safe". It is necessary for feed additive products to meet the requirements of health, safety and environmental protection while improving feed utilization rate and breeding efficiency, which is conducive to ensuring feed safety from the source, realizing green breeding and producing green animal source food. In addition, feed antibiotic additives have been widely used in animal husbandry in China since the 1970 s due to their antibacterial and growth-promoting effects. However, the abuse of antibiotics also brings a series of problems such as enhanced drug resistance, drug residues and environmental pollution. Therefore, "anti-resistance" has become an inevitable choice for the green development of the aquaculture industry and the protection of animal health and food safety.
