From July 8 to 9, 2022, the 2022 Second Ganyu Animal Husbandry Summit Forum (hereinafter referred to as Ganyu Forum) co-organized by the Jiangxi Animal Husbandry and Veterinary Society and the Guangdong Animal Husbandry and Veterinary Society was successfully held in Nanchang City, Jiangxi Province. The forum is themed "Pig Epidemic Prevention and Control and Nutrition and Health", and invited more than 20 authoritative industry experts to give wonderful reports. More than a hundred people including industry associations, scientific research institutions, leading enterprises, animal husbandry industry representatives participated in the forum. As the first national high-tech enterprise listed on the Science and Technology Innovation Board in the domestic industry, Shenlian Biopharma (Shanghai) Co., Ltd. (hereinafter referred to as Shenlian Biotechnology) was invited to attend the meeting.
Faced with the rapid development of current modern animal husbandry technology, it is both an opportunity and a challenge! The experts at the meeting conducted in-depth discussions on how the animal husbandry industry in Jiangxi and Guangdong provinces can develop in a coordinated manner, and focused on preventing illegality and disease control in the rainy season, preventing diarrhea and pig farm purification, and animal nutrition and health. The opening ceremony of the forum was chaired by Xie Jinfang, Vice President of Jiangxi Academy of Agricultural Sciences. At the beginning of the meeting, Liu Liang, director of the Jiangxi Provincial Animal Husbandry and Veterinary Bureau, the organizer Liu Liang, deputy secretary of the Party Committee and president of the Jiangxi Academy of Agricultural Sciences, Dai Xingzhao, chairman of the Guangdong Animal Husbandry and Veterinary Association and vice president of the Guangdong Academy of Agricultural Sciences, and Yang Hanchun, professor of the School of Veterinary Medicine of China Agricultural University and secretary-general of the Chinese Animal Husbandry and Veterinary Association, delivered speeches respectively, and wished the forum a complete success. In his speech, Liu Liang mentioned that this forum will focus on resource sharing and win-win cooperation, strengthen academic, talent, and scientific research and technology exchanges in the industry, and introduce that Jiangxi's total animal husbandry output value will be 25 billion in 2021, and the number of live pigs transferred is third in the country. At the same time, it is proposed that when providing social services, we should pay attention to the shortcomings in livestock and poultry breeding, animal nutrition, and biosecurity.
While the animal husbandry industry is developing rapidly, we should pay more attention to the harm caused by African swine fever in the rainy season. How to prevent and control African swine fever and establish a better biosecurity concept? Professor Yang Hanchun, Professor of the School of Veterinary Medicine of China Agricultural University and Secretary-General of the Chinese Animal Husbandry and Veterinary Association, delivered a report on "Strategies and Strategies for African Swine Fever Prevention and Control". At present, African swine fever has been in my country for 4 years, and the pathogenic strains are very harmful. Once indulged, there will be endless troubles. In addition, prevention and control is difficult, and precise removal is more difficult. Most farms need to be removed from the entire site, resulting in a decrease in my country's pig inventory and a decrease in pig population, which has long become a normal virus. The main risks of African swine fever are: internal and external environment, pigs, soil, transportation tools, water sources, personnel, etc. Under low temperature conditions, the viruses in pig carcasses and live pigs can survive for more than 6 months or even for several years. my country's pig industry continues to develop stably and healthily is a major need. There are currently no safe and effective vaccines and no effective measures, but eradication of plague is possible. Professor Yang Hanchun summarized: 1. Eradication of non-plague must be the direction of non-plague prevention and control and is an unshakable strategy; 2. Scientific and reasonable planning and improvement of the prevention and control system are the guarantee for the eradication of African swine fever; 3. Biosafety is the only effective and feasible strategy for the prevention and control of African swine fever in pig farms.
Going steady and far-reaching. Rebirth of newborn
F-and-mouth disease and African swine fever are listed as first-class epidemics in pig diseases. They are a global pandemic and are attached great importance to them by all countries. Mr. Wang Jianghui, technical director of Shenlian Biopharma (Shanghai) Co., Ltd., gave a report on "The Application of "Molecular Book Staple Technology" in Foot-and-mouth Inactivated Vaccine", which deeply analyzed why it is necessary to solve the technical difficulties of antigen stability of Foot-and-mouth Inactivated Vaccine inactivated Vaccine in three aspects: the current status of Foot-and-mouth Inactivated Vaccine inactivated Vaccine in three aspects: research on the technological innovation and application of "Molecular Book Staples".
Teacher Wang introduced the current situation of foot-and-mouth disease: Since 2012, FAO/WOAH has required member countries around the world to implement a five-stage gradual control path for foot-and-mouth disease. my country has fully understood the epidemiology of foot-and-mouth disease, the risk-based foot-and-mouth disease control plan, and is implementing the third phase of the eradication control measures. China's foot-and-mouth disease immunization control strategy is mainly based on vaccine immunity. my country has begun to study foot-and-mouth disease vaccines since the 1950s. At present, foot-and-mouth disease vaccines have reached the world's advanced level, mainly based on the continuous development of my country's foot-and-mouth disease inactivated vaccine processes.
Since 2007, due to the limited protection of the old strain, the pig foot-and-mouth disease vaccine vaccine has been replaced three times. Currently, the main types of O-Myanmar 98 poison and A-type pig poison are prevalent, so it is extremely important to choose excellent species. At the same time, the higher the antigen content of the vaccine, the better, and the antigen content is proportional to the neutralizing antibody within a certain range. The main problem with antigen content is that the continuous degradation of antigens as the storage time is prolonged. Due to the poor stability of antigen content, it has a great impact on the immune program in the pig farm. FTC research laboratories at home and abroad have confirmed through a large number of studies that the matching of foot-and-mouth disease vaccine strains and the stability of antigen content are the two key factors that determine the protective power of foot-and-mouth disease vaccines.
Breakthrough Innovation Running Light
Teacher Wang analyzed the source of the virus and summarized the three main factors that are prone to degradation of antigens inactivated foot-and-mouth disease vaccines. In order to solve the degradation problem, Shenlian Bio's scientific research team broke through conventional antigen protection technology and developed the "molecular staple" technology, which completely solved the technical problem of antigen degradation of foot-and-mouth disease inactivated vaccines. At the same time, after 20 months of finished vaccine testing, the effective antigen in each vaccine is still above 20 micrograms. The technological innovation of "Molecular Book Staples" solves the problem of vaccine stability from the source. After use, the number of blood collections is reduced, the overall antibody level after immunization is overall, and the immune program is stable, making the pig farm save time and effort while saving more worry and money!
Teacher Wang finally summarized: During the normalization of non-plague, four points should be paid attention to in the precise prevention and control of foot-and-mouth disease: 1. Vaccination is the most economical and effective prevention and control method; 2. Vaccination must be formulated to formulate a continuous and flexible immunization procedure; 3. Choosing excellent toxicity is more important than choosing content; 4. Choosing stable antigen content is more important than choosing a higher content.
Conclusion
As the degree of intensification of animal husbandry industry is becoming more and more complex, seriously affecting the health of the pig herd and the sustainable development of the pig farming industry. Based on strong scientific research technology and brand strength, the vaccine products and technologies launched by Shenlian Bio are surprising every time. As a touchstone and pathfinder for antigen preservation technology of domestic foot-and-mouth disease inactivated vaccines, the invention and innovation of the two-way antigen protection technology of Molecular Books i-MolSta is of milestone significance and has created a new era of antigen protection technology!
