Prospects for the development of feed additive biotechnology industry in Hunan Province

Introduction: the green environmental protection of feed additives is the development direction of feed additives Especially after some feed additives with more side effects such as antibiotics have been phased out, with the development of new generation products, environmental protection will become an obvious feature The future feed additives should have the characteristics of no pollution to the environment, no threat to human health, no drug residues and other side effects Feed enzyme preparation and microecological preparation and other feed additive biotechnological products come into being at the right time Their demand is increasing day by day, and their prospects are very broad Feed enzyme preparation is a kind of industrial product which contains single enzyme or mixed enzyme There are more than 1700 kinds of enzymes found in the world, more than 30 kinds of enzymes have been used for production, and more than 20 kinds of enzymes have been used for feed, most of which are hydrolysis enzymes, such as protease, cellulase, β - glucanase, pentosanase (arabinose, xylanase), pectinase, amylase, phytase, etc At present, except phytase is a single enzyme product, other feed enzyme preparations are mostly compound preparations containing a variety of enzymes Adding enzyme preparation can supplement the deficiency of endogenous enzyme and increase the enzyme which can not be synthesized by animals themselves, so as to promote the digestion and absorption of nutrients, improve the feed utilization rate and promote the growth of livestock and poultry A large number of experiments showed that the average daily gain increased by 5% 19% and the feed to meat ratio increased by 1% - 0% when enzyme preparation was used The improvement range was different due to the performance of enzyme preparation products, animal varieties and feeding stages Without the use of antibiotics and other drugs to promote growth and health care, the use of enzyme preparation can make up for the loss of production performance caused by the absence of growth promoting health care agent to a certain extent Therefore, the development of feed additive biotechnology industry is of great significance: first, to provide green feed for livestock and poultry, and then to provide safe, pollution-free and residue free livestock and poultry aquatic products for human beings; second, to protect the ecological environment and micro ecological balance between animals and nature; third, to reduce or replace antibiotics, and to reduce or limit the production of heavy metals and arsenic The dosage of agent and hormone can obviously improve the economic benefits and competitiveness of livestock and poultry breeding, not only meet the needs of domestic green consumption, but also enhance the ability of China's animal food to break through the "green barrier" in international trade.
