Animal husbandry calls for green

Introduction: the concept of Green comes from food It refers to the products grown and processed under specific technical standards Its standards cover the environmental quality standards of origin, production process standards, product standards, packaging standards and other relevant standards It is a strict whole process quality control standard system from soil to dining table "Green agriculture", "green vegetable", "green fruit", "green culture", "green feed" and "green feed additive" are derived from the concept of green food China's accession to the WTO has become a trend Although China's meat, egg and milk products have a greater price advantage in the international market, the market prospect is not optimistic due to the problem of drug residues Therefore, in the 21st century, one of the most urgent problems to be solved in animal husbandry is how to improve the quality, reduce drug residues, and gradually reduce or even prohibit the use of antibiotics as feed additives The production of green animal husbandry products has become the trend of the times Recently, the reporter interviewed well-known experts and professors in animal feed industry on how to promote the green production of livestock and poultry, ensure feed safety and the application of biotechnology in animal nutrition and feed industry Professor Feng Dingyuan, Dean of the school of animal science and technology, South China Agricultural University, thinks that the application of biotechnology in animal nutrition and feed industry has opened up a new way to improve the utilization rate of various nutrients in feed, promote animal growth and improve the health level of animals He said that the discovery of antibiotics and the successful synthesis of chemical antibacterial substances had played an important role in the prevention and control of animal diseases, improving animal production performance and increasing the number of animal products However, the disadvantages caused by the extensive use of antibiotics and drugs as growth promoters and disease control methods are increasingly widely recognized These problems include imbalance of micro ecological balance of animal body, drug residues in animal products and drug resistance of livestock and poultry to various drugs, which have become an important obstacle to the development of animal husbandry People have to find other ways to improve the efficiency of animal production and the effective use of feed resources In recent years, with the rapid development of biotechnology and genetic engineering, enzyme preparations, microbial additives, oligosaccharides, nucleotides, yolk antibodies and other feed additives have been used more and more in feed They have obvious effects in promoting animal production performance and improving animal health, laying a foundation for animal products to achieve "green" Mr Li Defa, director of the feed industry center of the Ministry of agriculture and doctoral director of China Agricultural University, believes that at present, we should vigorously promote the development of green feed additives He said that after China's accession to the WTO, China's livestock products will have certain advantages in international trade On the one hand, in terms of price, except for poultry, the price of meat in China's livestock products is lower than the international market price, of which the price of pork is about 50% lower than the international market; on the other hand, after China's accession to the WTO, China will liberalize the coarse grain market, and the price of corn and other coarse grains will be steadily reduced, and the feed cost will be low, which is conducive to the development of China's animal husbandry; on the other hand, after China's accession to the WTO, with the liberalization of the meat market And price advantage, export increased At the same time, the quality of meat products in the market will be more stringent, which forces the breeding industry to use green additives to improve the quality of meat products This will bring new development opportunities for the application of biotechnology in feed industry With the deepening of people's understanding of environmental and ecological sustainable development, people began to seek more safe, effective and residue free animal growth promoting agents and health care agents to replace antibiotics and chemicals It is gratifying that in recent years, some feed additives which have no direct or little effect on animal body, no harm to environment and human beings or even beneficial have begun to appear on the market These are called green feed additives, which represent the development direction of feed additives in the future, mainly including the development and application of enzyme preparations, oligosaccharides, Chinese herbal medicine, etc In the aspect of research on green feed additives, the research on feed complex enzyme preparations has been listed in the national "Eighth Five Year Plan" project, and some new topics have been set up in the "Ninth Five Year Plan" project "Green" and the application of feed enzyme preparation Liu Yali, director of research and development center of Zhuhai Special Economic Zone Yiduoli Co., Ltd., said in an interview that with China's accession to the WTO, the topic of "green" has been paid more and more attention, and "Green Olympics" has become China's commitment to the world For livestock producers, it is an urgent task to produce natural green livestock products without residue and pollution He said that the core issue of realizing the "green" of animal products is to use less or no antibiotics and other pharmaceutical feed additives The way to achieve "green" is to use green biotechnology products such as enzyme preparations, oligosaccharides, probiotics, organic trace elements and other green biotechnology products to gradually replace common drug additives, so as to solve the problems of disease prevention and production performance improvement in animal husbandry production According to the data, the commercial application of feed enzyme preparation in foreign countries has only a history of more than 10 years In the early 1990s, the adding rate of enzyme in chicken feed was almost zero, but now more than 95% of chicken feed was added with enzyme In our country, if we take the Yiduo enzyme introduced by Zhuhai Yiduoli company in 1992 as the starting point of commercial application of feed enzyme, the application of feed enzyme preparation in our country is only 9 years old After analyzing the new problems faced by feed industry, Professor Li Defa pointed out that different green feed additives have different mechanisms, approaches and solutions Practical experience tells us that it is a challenging task to replace antibiotics and produce green animal husbandry products It is difficult to achieve it completely relying on a single type of green additives In order to achieve better results, it is necessary for feed factories and producers to select several or several kinds of feed according to local conditions He said that after years of practice, it has been proved that the application of feed enzyme preparation in livestock and poultry breeding can not only improve the digestibility and utilization of feed, improve the production performance of livestock and fish, but also reduce the excretion of nitrogen and phosphorus in livestock and poultry excretion, and protect water and soil from pollution Therefore, feed enzyme preparation is a kind of "green" with high efficiency, non-toxic side effects and environmental protection ”Feed additives will have a very broad application prospect in the 21st century (author:) share to feed Weibo share to:
