    Reuters National Development and Reform Commission Ministry of Agriculture and other departments in the preparation of the "national animal epidemic prevention system construction plan." As of 2008, through the implementation of planning, China's animal epidemic prevention system improved gradually, to the strengthening of animal disease prevention and control work has played an important role.

    National Development and Reform Commission on June 24 message, 2004, against the avian flu epidemic in China's high rate, according to the State Council requirements, the National Development and Reform Commission and the Ministry of Agriculture and other departments prepare a "national animal epidemic prevention system construction plan (2004-2008)" . "Planning" for animal epidemic prevention system of weak links, made six of key construction projects:

    First, animal disease prevention and control center project. Focused on building national and provincial animal disease prevention and control center.

    The second is the grass-roots level animal epidemic prevention infrastructure projects. Focus on building and perfecting the 1,825 county-level and the Xinjiang Corps, Farm Animal Epidemic Prevention Station farm system (including animal epidemic monitoring and border animal epidemic monitoring stations), 18,700 township veterinary stations, 490 county-level aquatic animal epidemic prevention stations and 250 Lu Health and wildlife focus of disease monitoring stations.

    Third, quarantine supervision of infrastructure projects. Focus on building and perfecting the provincial, county, township 3 Animal Health Authority (stations), in which township quarantine supervision of infrastructure construction into the township veterinary considered together, improve the animal epidemic prevention supervision and inspection stations and exit inspection and quarantine facilities.

    Fourth, the residues of veterinary drugs and monitor the quality of infrastructure projects. Focus on improving the building of national and regional veterinary drug residues monitoring and evaluation of the quality of institutions, as well as by the provincial veterinary medicine quality supervision, improve the immigration drug residue monitoring facilities.

    Fifth, the national animal epidemic prevention technical support for the project. Focus on building and improving national and regional animal disease diagnostic laboratory, veterinary microbiology center, the pathogen, such as the vaccine antigen reserves.

    Sixth, veterinary biological products production projects. 17 focus on enabling enterprises to vaccine production of GMP.

    As of 2008, all in the planning of the central, provincial, county-level animal epidemic prevention projects and infrastructure construction in the country 50 percent of the township veterinary stations have been arranged investment, a total of 7.48 billion yuan investment, of which 4.98 billion yuan investment in the central and local Invest 2.5 billion yuan. Through the implementation of planning, China's animal epidemic prevention system improved gradually, to the strengthening of animal disease prevention and control work has played an important role.

    First, major animal disease prevention and control capability has been enhanced. In addition to small ruminant OIE only in the implementation of immunization in individual districts, the other major animal diseases immune density of more than 90 percent. Provincial, county, township epidemic monitoring and reporting system have been gradually perfected, the provincial, city and county levels of major animal epidemic emergency response system improved gradually, the ability to deal with emergencies has been constantly strengthened. Major animal epidemic decreased significantly, the major animal epidemic outbreak and the number dropped significantly.

    The quarantine is markedly improved the level of supervision and law enforcement. Animal health supervision and law enforcement work has been strengthened since 2004, around the animal health inspection and quarantine institutions a total of 20 billion animals (only), animal products and quarantine 2.6 billion tons, the animals were unqualified 80 million (only), failed animal products 70,000 tons, all in accordance with the relevant provisions of the treatment.

    Third, the capacity of veterinary drug industry monitoring continuous improvement. Veterinary medicine quality supervision and monitoring work capacity and residue levels were significantly improved, veterinary drug manufacturing enterprises and the use of part of monitoring has been strengthened, veterinary drug business gradually standardize the order, the Chinese steadily improved the quality of veterinary drugs, veterinary drug residues超标was significantly lower. 2007, poultry products veterinary drug residues超标rate dropped to 0.5 percent than 2002's 5.6 percent decline by 5 percentage points.

    Fourth, science and technology support system has been strengthened. Has taken shape veterinary laboratory network system, the avian flu, foot and mouth disease, mad cow disease and other major animal disease diagnostic laboratories and national reference laboratory as the mainstay of various types, a clear division of laboratories, operating efficiency, significantly enhance the role of scientific and technological support, In the avian flu, the Asian type I foot and mouth disease, pig-borne disease and highly pathogenic blue ear pig disease and other major animal disease prevention and control work, play an important role.

    The article to share with others:
    First, the leaders attach importance, grasping work arrangements. Xianju convened communes (town) station layout for a meeting of major animal disease-free work, the Secretary personally, and issued a "do a good job on major animal disease-free work-notice", by the animal disease control center in charge of grasping Implementation.

    The second is meticulously organized and grasping the investigation and mapping. Organization animal husbandry and veterinary technical cadres and members of village-level animal epidemic prevention in-depth village, the scale of livestock breeding farms and large, the kinds of livestock and poultry, Danqin into the field and 5-6 in the livestock and poultry and compulsory vaccination in the investigation and one by one immunization procedures, By asking the owners to view the file immune to find leak-free, the new Bulan, has been immune to the period of time not to fill the avoidance or strengthen the immunity of livestock and poultry to register. According to the investigation, Woxian shall be free of classical swine fever 8640, highly pathogenic blue ear pig disease 8329, avian flu 21,200 chickens, 37,300 ducks bird flu, geese 500.

    Third, it is not completed in time, grasping vaccination effectiveness. Not immune to the livestock and poultry epidemic prevention organizations in time for staff meeting or supervision and guidance to owners of livestock and poultry-free. Effectively "should be free to make free, do not stay free."

    Fourth, the material protection, grasping vaccine supply. The timely transportation for compulsory vaccination of varieties and quantities of vaccine, hog cholera vaccines have been transferred to 10,000 copies, the highly pathogenic blue ear pig disease vaccine 10,000 copies, the avian flu vaccine in a total of 50,000, and other various vaccines Beizu . In strict accordance with requirements of the custody and transportation of vaccines to prevent the use of invalid Miao.

    Fifth, the supervision and inspection and monitoring grasping effect. Xianju organization personnel to go to township and village supervision and inspection-free work, the inspection found problems, timely rectification and reform to ensure that the work completed for the smooth conduct. Focus on strengthening the families of professional poultry, livestock and poultry live poultry market place to monitor the work of the immune antibody was less than the requirement to promptly fill-free or strengthen immune to ensure that the animal's immune antibody存栏qualified standards.

      Analysis of the reasons for failure of immune poultry disease
      [Published :2008-7-14]

      1. chickens in individual differences

      Because the immune response by many genetic factors and environmental factors. In a random flocks, the immune response was inclined to the scope of normal distribution, which means most of the chickens on vaccine immune response was the middle level, while a small portion of the vaccine for the poor immune response. Despite the small number of chickens have been vaccinated, it can not receive adequate protection against infection of chickens in this part of the low immunization with the number depending on the nature of the vaccine. The vaccine antigen as possible, the higher the intrinsic quality, low protection of the chickens the less. The highly contagious disease, even in the presence of a small number of unprotected animals, once encountered pathogen infection, will also cause the spread of the disease prevention and treatment plans and lead to the failure of white. Therefore, we should also attach importance to the environmental disinfection and sterilization work to minimize pathogen contact with chickens opportunities.

      2. Chickens in the normal immune response by inhibiting

      As immune suppression so that the body after the vaccination can not produce the expected immune protection, the immune suppression caused a lot of reasons:

      ① the poor health of the body, especially the presence of certain diseases, immunization. Factors such as chicken anemia virus, infectious bursal disease virus and Marek's disease virus infection.

      ② stress response. Such as the ones in overheating, cooling, climate change suddenly, chicken density is too large, frightened group to group and the sudden replacement of feed,
      Changes in light, osmium, such as hunger, can cause chicken in the vaccine reduced the immune response.

      ③ immunization program design unreasonable, especially for maternal antibodies or antibodies in residues not fully consider the impact. These antibodies can inhibit attenuated vaccine so that it can not in the proliferation of chicken, so that immunization failure. In addition, a variety of vaccines to use or similar time-use, the vaccine could be interference between the role. If the vaccine can interfere with bronchial infectious Newcastle disease vaccine, the weak germ of the Newcastle disease epidemic prevention effect reduced.

      3. Vaccines and the choice of inappropriate use

      ① immunization method unreliable. Each vaccine has its best immune channels, such as arbitrary changes will affect the immune effect. Injection, drinking water, points eyes, intranasal not the correct action in the part of both individual and groups can not get enough of the vaccine, thus affecting the quality of immunization.

      ② latency period of vaccination or immunization gaps infection. In the affected areas have not been exposed or the chicken immune disease, often part in the vaccination of chickens have been infected with pathogens, and are in incubation period, when vaccination may trigger the disease. After the vaccination, the body has a process to identify and respond in this process, the immune resistance gradually increased, reached the peak before gradually decay. After the vaccination of chickens to generate sufficient immunity before the period known as the immune blank period, during this period if the highly virulent pathogen infection, the failure will lead to immune.

      ③ inappropriate choice of vaccine. Selection of vaccine serotype with the market, the region epidemic pathogenic serotypes in line. Selection of the vaccine should be applied to the nature of chickens to the age and physical stage. The quality of the vaccine should be up to standard, Ruodu Miao, the key is dynamic, inactivated vaccine is the key to effective content, otherwise, may lead to immune failure.
