Professor Chen Yaosheng is chief scientist of national pig industry technology system
First of all, is a leading authority on pig breeding, pig industry technology system of chief scientist professor yao-sheng Chen report topic is "the science and technology innovation and the development trend of China's pig industry, the influence of the content is divided into epidemic of pig industry, scientific and technological innovation leads the industry after becoming the butterfly and the blast time refactoring of swine breeding system.
First of all, Professor Chen used the following words: "Be fearless in the face of danger, be firm in your confidence, have a clear understanding of the situation, look at the overall situation, deal with it scientifically, focus on the future, grasp the general trend, do a good job in top-level design, and never press the brakes!" A few words let us correctly understand the situation of pig industry.
The layout of pig industry in China is divided into key development areas, restricted development areas and potential development areas. Under the impact of African swine fever, seven major defects of pig industry have been exposed and their long-term impact has been caused. In the future, long-distance trafficking of live fat pigs will not be banned, and long-distance trafficking of breeding pigs will also be greatly reduced. For pig farms with a certain scale, live pigs should be eliminated as far as possible, so that no live pigs can enter. Professor Chen also points out that the most profound lesson of AFCD is the circulation of live pigs.
African swine fever may be a fatal blow to more than 90% of small and medium-sized farmers, but it is a godsend for the leading enterprises in the industry's core competitiveness. In 2018, the market share of top30 breeding enterprises is about 15%, and by 2020, this proportion is expected to exceed 50%, forming an oligopoly market.
Pig industry key technology are mainly concentrated in breed, feed, disease, and product and waste as well as facilities six aspects, the key point is breeding introduction and varieties of form a complete set, the key to feed technology is a precise formula and precision feeding, disease, treatment, and focuses on vaccine disinfection, direction of biological safety and health without resistance, the mainly around the resource recycling of waste disposal and ecological friendly, facilities in overall introduction and efficiency, finally realizes the product safety and quality.
Nutrition of pigs:
Chen Daiwen, vice President of Sichuan Agricultural University
Pig nutrition experts, vice President of sichuan agricultural university professor dai-wen Chen's report is the development trend of China's animal nutrition, animal nutrition were analyzed in three aspects of the theory, technology and practice achievements, but at the same time it faces many theoretical problems, such as focus on nutrients, focusing only on the input and output, intestinal problems, idealized static, to feed cognitive deficiencies;
Under the guidance of the theory of mismatching, can not eat, poor effect, low utilization, great harm of the application of the problem, in a word, the current situation of feed nutrition is unbalanced and inadequate.
The current situation of feed nutrition urgently needs theoretical and technical breakthroughs. Theoretical breakthroughs focus on precision nutrition, including eight theories of animal nutrition, nutritional needs, animal nutrition system concept, nutrition and animal health, nutrition and animal production, nutrition and meat production, feed utilization mechanism and animal nutrition methodology.
In terms of animal nutrition innovation, six technological innovation directions were introduced:
(1) For the future feed industry's main functions: nutrition source transformation and additive creation
(2) The main function of scientific and technical personnel: nutritional value and nutritional needs
(3) The main function of the formulator: nutritional structure and nutritional balance
(4) The main function of the breed end formulator is to prepare full price and global feed
(5) Feed processing at the aquaculture end: use fermented feed
(6) Aquaculture end feed modulation: the use of fluid feed
The innovation of feed technology can be summarized as 3F technology:
Formulation: To optimize nutritional structure and meet accurate requirements
Fermentation: Modification of chemical structure and improvement of efficiency
Fluid feed: The modulation of Fluid feed and increase in feed intake

Laying hens:
Zhou Precious, Secretary of the Party Committee of Beijing Huadu Yukou Poultry Industry
In Beijing Huadu Yukou Poultry industry, which has a history of 40 years, Party Secretary Zhou Guicheng presented the title "Scientific and technological Innovation and Development Trend of China's laying chicken Industry". China's laying chicken stock ranks the first in the world, about 1.207 billion, accounting for 31.35% of the global total. The output of eggs ranks the first in the world for 32 years in a row, and the per capita consumption of eggs is 18kg, ranking the third in the world.
The national laying chicken industrial system has achieved five breakthroughs through 10 cows. First, 14 supporting layers have passed the national new Variety examination, and the market share of domestic varieties is more than 70%. Second, the integration and demonstration of standardized large-scale laying hens breeding technology, and the establishment of hundreds of national laying hens breeding standardized demonstration farms; Third, the purification effect of vertically transmitted diseases was remarkable, and the evaluation test station was the first to realize the purification of avian leukaemia. Fourth, carry out scientific research to reduce burden. A-vii vaccine has solved the technical problem that the strong virus of Newcastle disease epidemic cannot be weakened by traditional methods. The fifth is the creation of the world's only microecotype mycotoxin explanation agent.
As one of the three largest laying chicken breeding companies in the world, Huadu Yukou Poultry Industry takes the lead in many aspects in China and even in the world. They have independently cultivated three series and ten varieties of egg broilers, such as Jingfen6, which produces the most eggs in the world and has a smaller egg weight. The biosafety model of 4335 was established, which was the first to achieve the breakthrough of zero positive rate of leukemia in chickens. Taking immune program optimization as the core, it follows 2 principles, 3 laws, 4 aspects and 5 supports to practice scientific burden reduction. In addition, a "menu-style" accurate nutrition supply scheme was created. In China, the "stacking cage + artificial insemination" model for six-layer breeding chickens was pioneered, and a platform for intelligent laying hens was developed.
In the 40 years of development of Huadu Yukou poultry industry, they insist on the original intention, insist on doing something, do something; In breeding, broilers do not pursue fast growth, laying hens do not pursue more eggs; Do not do full coverage immunity, laying hens 21 days not immune, egg production period not immune; Not all vaccines are immune. For vertically transmitted diseases, source purification is needed; for environmental conditioned diseases, biosafety + scientific feeding management is needed; and for immunologically controlled diseases, scientific immunity + biosafety is needed. Do not block field, do not plant trees; Do not do omnipotent feed; Do not do the production mode of this delivery.
For the future, The goal of Huadu Yukou poultry industry is to achieve a balance between three high yields, high efficiency and high benefits, with a basic balance between supply and demand, so that China's laying chicken industry can develop healthily.
Beef cattle:
Cao Binghai is chief scientist of the National Beef cattle industry Technology System
Professor cao binghai, chief scientist of the national beef cattle industry technology system, wrote in his report "the scientific and technological innovation and development trend of beef cattle industry in China". He listed the Top10 research hotspots in global agriculture in 2019, including animal nutrition and its economic nature, animal epidemic prevention and control, and animal pharmacology.
The report showcases technological innovations in beef cattle such as multiple calves, key points being screening for drug-sensitive cows, dosing, timing of ovulation induction, and luteal number tests. This technology has advantages and disadvantages: the disadvantages are that the operation technology needs precision and proficiency, the management intensity needs to be increased, and the cost is increased by 200-250 yuan/cow; The advantage is that the pregnancy rate is 15-20% higher than the usual technique.
The demand trend of beef cattle industry :(1) the demand space of beef is large; (2) Due to the increasing demand for personalized consumption, the market level is segmented, so the market should be featured and differentiated; (3) As the whole cattle raising population is decreasing, the breeding cost is increasing, the import volume is increasing, and the pressure of environmental protection is increasing. So in the future, competition will intensify and challenges will increase; (4) The power of promotion mode is far greater than that of promotion technology, and tailor-made diversified policies are urgently developed.
These pigs, broilers and laying hens, beef cattle in the field of scientists higher-ups or enterprises, they are studying, solid work, made extraordinary contribution in their area, some results or the world's leading, as the animal husbandry industry colleagues, these scientists research results, direction, or whether that brought some inspiration for you?
