Feed additives in China and abroad, the level of development compared Feed additive level of technology compared (A) of the feed additive industry, meaning the development of national economy Present, parts of the world distribution of feed additives production of about 34.8% in North America, Western Europe 21.3%, Eastern Europe, Russia, about 13.5%, 11.4% in Asia, Central America 11.1%, Japan 6.1%. Countries of the world total nutritional feed additives, 55% additive to 60%, 30% of veterinary drugs and 35%, biological products accounted for 10% to 15%. United States, annual consumption of feed additives 6.5 million t, EC 5.6 million t. 2008, about five million Chinese premix t, the output value of about 300-400 billion. Feed costs account for two thirds of the cost of breeding, feed additive technology is the core technology, bio-technology is the core technology of additives. Therefore, the development can promote animal performance, security, new sound animal husbandry and feed additives industry has been a priority issue. Feed additives industry in China in recent years, a qualitative change in the basic realization of the mainstream products made in China by importing countries to become exporters; additive trend of mainstream development of new products by a series composed of biotechnology, including antibiotic alternatives, feed enzymes, microbial preparations, plant extracts, fermented feed, genetically modified forage crops. Is worth noting that: (1) Although our feed enzyme industry started in 1990, but 12 years has made considerable progress, as the first home-made feed, genetically modified phytase enzyme from the research and development, production, application to export trade won the shoulder to shoulder together with the foreign products gratifying situation; (2) of the new century in just 3-5 years time to realize that the first amino acid lysine feed importers to exporters from the change, the two shows a typical product of the tremendous progress in biological feed additives industry in China's technology and product technology content have contributed to a new level and stage, with the signature landmark; (3) the plant extract is an important alternative to feed antibiotics, one of , plant-derived herbal medicine is the development and application in China has thousands of historical cultural legacy, is still a plant germplasm resources, recipe formulation, clinical application of thousand years of international advantage, short-board in the mechanism of separation of research and engineering. The three additives in China's comparative advantage in R & D in China are reflected in international standards, industrial development, international strength and a long thick cultural characteristics is the "three excellent." Three of addition to the above highlights, the core technology of feed additive product surface and the developed countries at the macro still obvious gap is "a worry." The terms "three distinctions and one worries" a brief description of the main line of technological development of biological feed additive status at home and abroad, put forward "to meet the health, safety and environmental protection, the new requirements of economic development, need the latest technology, especially biotechnology feed additive R & D to ensure sustainable development of China's feed industry "approach. (B) of the five biological feed additive product research and development of domestic and foreign technology As feed additives to the efficiency, safety, environmental protection, multi-direction, the use of modern biotechnology and other high-tech research on animals with specific biological activity and function of the new security feed additive --- including amino acids, feed active peptides, feed enzymes, probiotics, and plant extracts such as five types --- have become the technological development of biological feed additive main trends. 1, foreign research and development of biological feed additive technology To genetic engineering, protein engineering and metabolic engineering is the core of modern biotechnology has become the new century, the development of biological feed the mainstream. Eight of the last century, the nineties, to genetic engineering and protein engineering and other high-tech achievements in the field of industrialization enzymes and amino acids developed genetically engineered bacteria and industrialization are the epoch-making results. At present, the developed countries, basically the main feed amino acid and enzyme genetic engineering technology; peptide core technology development or genetic engineering and biochemical engineering, its successful application in feed industry marginal profit is the key to lower costs, more efficient screening broad-spectrum antimicrobial effects and safety or the new product, which is running through the field of multi-disciplinary and international research hot, the bottleneck technological breakthroughs yet to time, there are quite a distance up to the utility. The metabolic engineering of genetic engineering and protein engineering than to high-level, complex and more difficult, has important methodological significance. With modern separation techniques, combinatorial chemistry, metabolomics, pharmacology and pharmacy combination in the application of plant extracts in the alternative feed antibiotics will play an important role.
