Biological feed additive: against antibiotics

Introduction: Archives: as early as ten years ago, medical experts have been crying out: the abuse of antibiotics has become a hidden killer that endangers people's health If it has been a long time, ordinary people will fall into a hopeless situation without drugs To this end, our government also recognizes the seriousness of the consequences, antibiotics have been listed as prescription drugs, strict management But in addition to doctors' prescription drugs, some local breeding industries abuse antibiotics, resulting in the transfer of antibiotic residues in food to the human body, causing people to suffer unconsciously Research and development of biological feed additives is a national scientific and technological research project Aiming at the serious problems such as drug residue and low quality of animal products caused by blind abuse of feed additives in feed industry in China, 12 new products, such as new nutritional regulators, are developed by the extraction process and application technology of plant flavonoids These 12 new products are all natural products from plants, which play a decisive role in preventing drug residues in animal products Experts comment: the terrible degree of antibiotic resistance and drug-resistant consequences is beyond everyone's imagination, but without the use of feeding antibiotics and other drugs, livestock breeding is easy to get sick and die, and the farmers will not do it Therefore, it is necessary to develop alternative technologies and substitutes The effect of biological products is not as obvious as that of antibiotics and is not easy to be accepted The effect of biological feed additive is aftereffect and mild Long-term use of biological feed additive can enhance animal autoimmune function and sensitize pathogenic microorganism In addition, for livestock, the healthy completion of its life cycle requires many aspects of care We can not rely on some or some drugs for its life, otherwise, it is not only livestock and poultry, but also our human beings who are injured Only careful breeding can benefit animal health and produce healthy products For the users who use the biological feed additive products, they also need to improve their own technical quality If we set up the idea of "nourishing over preventing" in the minds of the majority of users, I believe that the products of biological feed additive will be easily understood and accepted by the majority of users, and the ecological era of feed industry will come soon The quality of livestock products in China will be steadily improved, and both at home and abroad will be willing to accept our livestock products, so that our livestock production country will become a real livestock production power Change: first, from passive tracking to active adjustment Feed antibiotic is a kind of product widely used in the world In the 1990s, the production technology of this kind of product was mainly concentrated in developed countries such as the United States, Germany and Japan China's feed antibiotic products all rely on imports, not only the price is more expensive, but also because the exact ingredients of the products are not clear, the application technology is also restricted by people Through the national scientific and technological research, especially for the production, application and growth promoting mechanism of feed antibiotics for ten consecutive years, great changes have taken place in the technical mastery and product production in this field in China In terms of products, China has all the existing products abroad, and there are considerable technical reserves In terms of production technology, the content and level of science and technology lead the world As we have abundant technology and product resources, we may take the initiative to adjust Secondly, the transition of feed additive from chemical age to biological age was realized The basis for the transition includes three aspects: first, almost all the research and development means adopt biotechnology, such as microbial fermentation, enzyme engineering, etc.; second, all the new products successfully developed are environmental fusion products, such as microecological agents, plant extracts, etc.; third, since 2000, the animal health feed additive products in China have changed from chemical drugs to biological drugs Mainly feed additives Finally, guide the research and development of domestic new feed additives to progress towards the ecological era In the process of scientific and technological research in the tenth five year plan, not only the task of scientific and technological research has been successfully completed according to the contract requirements, but also how to carry out the research and development of new feed additives under the consideration of ecological protection has been studied For example, "non targeted screening technology" is proposed for the research and development technology of microecological preparations Through this technology, the new strains screened in the future not only have the exact physiological regulation function, but also will not bring any adverse effects on the ecological balance In addition, this screening technology can also be applied to the screening of effective components of traditional Chinese medicine Experts comment: chemical drugs are one-to-one "fight", which is easy to go from one extreme to another artificially Ecological preparation is characterized by overall co-existence These substances can not only effectively limit the excessive proliferation of target bacteria, but also regulate the immune balance in the organism Through the establishment of a strong defense system, animals can grow healthily and naturally At present, according to the safety, China's Ministry of agriculture has clearly divided them into two categories: one can be used as feed additives, the other can only be used as drugs but not as feed additives Recently, a prescription veterinary drug management system has been introduced Such management measures are unprecedented in China and the most advanced in the world, which are inseparable from the support of national scientific and technological research Achievements: "Research and application of high efficiency microbial feed additive" has won the second prize of Beijing Science and technology progress award Its good effects are mainly shown in three aspects: first, replacing feed antibiotics, eliminating drug residues, sensitizing pathogenic microorganisms, and improving the quality of livestock products; second, consolidating soil nutrients, reducing nutrient loss caused by irrigation or rainwater scouring, and water body The third is to absorb and digest the odor of breeding, so as to improve the living environment of livestock and poultry and the working environment of breeders Through the above three aspects of comprehensive role, to achieve the purification of breeding environment, prevent and alleviate breeding pollution Expert comments: in addition to food safety and environmental benefits, scientific and technological achievements can significantly enhance the market competitiveness of related enterprises' products and achieve significant economic benefits For example, in 2000, a company used "high-efficiency microbial feed additive" to produce eggs, which is popular with consumers for its safety, good taste and high nutrition In more than four years, the sales volume has been increasing by 30%, and now the annual output value is over 100 million yuan "Research and development of biological feed additives" is trying to achieve its purpose, that is, the overall consideration and coordinated development of economic benefits, social benefits and ecological benefits Reporter: Li He, Luo Hui, Hu Weiyuan topic Description: review expert on research and development of biological feed additives: Tong Jianming (researcher of Animal Husbandry Research Institute of Chinese Academy of Agricultural Sciences, doctoral director of Graduate School of Chinese Academy of Agricultural Sciences) ■ core tips: due to the production mode of quick success and instant benefit of human beings, forests have become cities and fields have become factories The living environment of human beings is being seriously threatened El Nino, sandstorm and red tide remind us not to forget to protect our living environment when calculating the money in our pocket The large-scale breeding, which came into being at the beginning of last century, has driven the development of feed industry all over the world As the core additive technology of feed, it has attracted the enthusiasm of many enterprises and scientific research departments with its high technical content and good economic benefits In the past 100 years, hundreds of products have been produced Most of these products are aimed at promoting growth, such as feed antibiotics However, while we have achieved the results of "seedling feeding" animal products, what we lose may be human health The purpose of science is undoubtedly to benefit mankind and all things related to mankind The project team introduced in this issue is to prevent human beings from "throwing stones at their feet" and to control the safety of animal food at the source.
