Prospects of animal science and technology in China at the beginning of the new century

Introduction: in the past 20 years of reform and opening up, the development of animal husbandry in China has made remarkable achievements The main animal products have grown at a rate of about 10% for 20 consecutive years, and the output of meat, eggs and milk has increased by 6.5 times, 8.2 times and 7.7 times respectively, which has completely changed the situation of serious shortage of animal products market in China for a long time The rapid development of animal science and technology in recent years is inseparable from the great achievements of animal husbandry in China in a short time The role of animal science and technology is particularly prominent in the research, promotion and application of new technologies such as animal breeding, disease control, compound feed and additives, feeding management, etc The successful breeding of a large number of excellent breeds, such as China's new lean meat pig line, China's Merino sheep, China's Holstein cattle, etc., the development and use of equine infectious anemia and swine fever vaccines, the advent of animal embryo and somatic cell cloning, in vitro fertilization, embryo engineering breeding, molecular marker technology and transgenic animals, piglet diarrhea genetic engineering vaccine, monoclonal antibody and The research and application of high and new biotechnology, such as nucleic acid probe, not only effectively promoted the development of animal husbandry, but also made the level of animal science and technology in China maintain the world leading level in some fields Animal science and technology has also created huge social and economic benefits in actual production Taking Northern China as an example, in order to solve the supply problem of meat, eggs and milk products in cold areas, the "standardized plastic film greenhouse technology for livestock and poultry breeding" has been promoted From 1992 to 1995, the market has been provided with 2.4 million tons of meat and 500000 tons of eggs, More than 3 million tons of feed were saved, and the direct economic benefit reached more than 3 billion yuan The contribution rate of scientific and technological progress to the economic growth of animal husbandry in China has increased from 31.4% at the end of the sixth five year plan to about 50% at present Rn5 21st century will be the era of knowledge economy The rise and development of knowledge economy will have a significant and far-reaching impact on all areas of human social life, including animal husbandry At present, the contribution rate of scientific and technological progress to the economic growth of aquaculture in developed countries is generally 60% - 80% Compared with them, China still has a big gap This also shows that the development potential of animal science and technology in China in the new century is huge At the beginning of the new century, China's Animal Science and technology will probably make new breakthroughs and progress in the following areas The industrialization of rn5 animal science and technology will be accelerated With the continuous development of the market economy system, the scientific research system of the planned economy will undergo major changes: the relationship among science and technology, industry and market will be closer, market demand and competition will increasingly become the direct driving force for the development of science and technology, and enterprises and scientific research departments will take the initiative to combine science and technology, production and market organically, both of which are scientific research and production It will be carried out around the market, thus it is possible to produce a number of high-tech breeding enterprises to drive the development of science and technology in the whole industry The application of high and new technology in animal science and technology will be more and more extensive, and may have a far-reaching impact on the development of breeding industry, such as gene engineering, cell engineering, bioengineering, cloning technology and other cutting-edge technologies, which will be more widely used in production at the beginning of next century The application of some protein feed and monoclonal antibody diagnostic reagents has a broad prospect and will achieve significant economic benefits The development of rn5 conventional technology still has great potential Compared with the developed countries in the world, China's aquaculture production level is not high, and the production of the same amount of animal products consumes more feed resources than other countries It is the only effective way to ensure the supply of animal protein in China to select large-scale breeding, improve production efficiency and develop the production of animal products Therefore, animal science and technology will have a great development in the research and promotion of modern intensive breeding, good supporting livestock and poultry breeding, integrated disease control, feed mix, environmental control, slaughtering and processing, harmless waste treatment and other technologies The selection of animal breeding species will tend to be diversified, while species will tend to be concentrated Market demand and consumption habits determine that pigs, chickens, cattle, sheep and other livestock and poultry will still be the main types of animal breeding in China, but the degree of improved breeding will be greatly improved, and the varieties will be more and more concentrated on a few international excellent varieties At the same time, with the development of diversified market demand, animal breeding species will tend to be diversified, and the development of special breeding industry will make animal breeding industry enter a broader field In line with this, the scope of animal science and technology research and development will be further expanded Rn5 information network technology and computer application in animal science and technology are more and more important The wide application of computer information network technology is the main driving force for the society to enter the knowledge economy The emergence of the Internet has realized the global information sharing and changed the traditional concepts and methods of market, scientific research and management The application of computer and the information network based on Internet will play an important role in the research, popularization and application of animal science and technology Rn5 (author:) to feed Weibo to:
