The best doctor for animals is their own immune system. Only the normal operation of the immune system, the body will be strong, in order to effectively resist the invasion of most diseases. The immune system of poultry is composed of multiple organs of the body working together in coordination. The immune organs are divided into central immune organs and peripheral immune organs. The central immune organ is the place where all kinds of immune cells occur, differentiate, develop and mature. Peripheral immune organs are the sites where lymphocytes and other immune cells colonize, proliferate, and generate immune responses. Central immune organs include: thymus, bursa, bone marrow. Peripheral immune organs include: spleen, intestinal lymphatic tissue, paramural lymph

The life cycle of coccidiosis is generally 4-7 days, the asexuality period is 3-5 days, the sexual reproduction period is 2 days, and the formation of sporulated oocysts in vitro only takes about 1 day. The wall of the coccidia oocyst has two layers, the outer layer is a protective membrane, strong, with greater elasticity, and the chemical composition is like keratin; the inner chemical composition is lipid-like, and the protoplasm is granular. Because of such a special protective structure, the resistance of coccidia oocysts is very strong, and they can survive in the soil for 4 to 9 months. Oocysts are extremely resistant to common disinfectants. Any fodder contaminated by the feces of diseased chickens or chickens with insects,

1. salt poisoning: excessive salt intake, common symptoms are thirst, collapse, paralysis, restlessness, limb weakness and so on. 2. Ammonia poisoning: due to poor ventilation, the harmful gas in the chicken house cannot be discharged in time, and the ammonia gas is very harmful to the chickens. Ammonia poisoning chickens, often manifested as: cockscomb purple, poor appetite or even waste, but like to drink water; eyes and oral mucosa congestion, head breathing, convulsions before death. Ammonia poisoning more serious chicken flocks, more located far away from doors and windows. 3. Fluoride poisoning: due to the frequent use of stone powder in the chicken industry, and the high fluorine content, exceeding the standard will cause chickens

Foreign media said that British scientists have used gene editing technology on chicken cells cultured in the laboratory to prevent the spread of avian influenza. This is a key step in the development of genetically modified chickens that can prevent the outbreak of human influenza. According to a Reuters report on June 3, researchers from Imperial College and the Roslin Institute of the University of Edinburgh in this latest study changed a part of chicken DNA in cells cultured in the laboratory to prevent the avian influenza virus from being in the cell. Survive and replicate. Mike McGrew of the Roslin Institute, who co-led the research, revealed that the next step will be to breed the genetically modified chickens. "This is a heavy

The warm and wet season provides favorable conditions for the reproduction of coccidia. If we want to treat coccidia, the environment must be improved. The life history of coccidia is generally 4~7 days, the asexuality period is 3~5 days, the sexual reproduction period is 2 days, and the formation of sporulated oocysts in vitro only takes about 1 day. The wall of the coccidia oocyst has two layers, the outer layer is a protective membrane, strong, with greater elasticity, and the chemical composition is like keratin; the inner chemical composition is lipid-like, and the protoplasm is granular.

Taiwan's Changhua County Animal Disease Prevention and Control Institute received a report of abnormal death of chickens from a native chicken farm in Erlin Town on the 19th. It sent personnel to carry out movement control and collect diseased chickens for examination. On the 24th, it was confirmed by the Animal Health Laboratory of the Agricultural Committee that it was infected with H5N2 subtype highly pathogenic avian influenza virus. Epidemic prevention personnel entered the site on the 25th to complete the culling and disinfection work, with 27,103 native chickens. The temperature has risen, but the bird flu virus has been localized and will occur all year round. Dong Mengzhi, director of animal epidemic prevention in Changhua County, called on poultry to reduce their resistance due to rapid climate changes. Poultry farmers should pay attention to ventilation or warm measures in poultry houses. Changhua County

Chronic respiratory disease of laying hens is a disease with clinical symptoms mainly in the respiratory tract, which is easy to be repeated. It usually occurs more often in winter and spring. Due to the invasion of cold air and the high density of chickens, it is easy to occur when the house cannot be well adjusted for heat preservation and ventilation. Clinically, the causes are more numerous and interactive, making it more difficult to determine and eradicate than a single infection. Causes of disease: when chickens suffer from certain infectious diseases, such as Newcastle disease, influenza, branch transmission, larynx transmission, mycoplasma, Escherichia coli, etc., can cause chronic respiratory diseases. In addition, when viral respiratory diseases and Mycoplasma gallisepticum invade the chicken body at the same time, it can enhance its

Infectious rhinitis is an acute respiratory infectious disease of chickens caused by Haemophilus paragallinarum. The main manifestations are inflammation of the eyes, nasal cavity and suborbital sinus, facial swelling and running water-like nasal fluid. The disease has a high incidence, rapid spread, often mixed with chronic respiratory disease, colibacillosis. The growth and development of breeding chickens are poor, the laying rate of laying hens decreases by 10-40%, and the economic loss is large.

The EcoAnimal Health Organization, headquartered in the United Kingdom, is about to start developing a live attenuated poultry mycoplasma vaccine after signing a second agreement with the University of Georgia in the United States. The University of Georgia in the United States followed an arrangement with the Ecological Animal Health Organization to develop a potential vaccine for Mycoplasma gallisepticum. Researchers at the university have conducted an initial proof-of-concept of the effectiveness and safety of this new vaccine. PeterLawrence, Non-Executive Chair of EcoAnimal Health, said: "Mycoplasma is a bacterium that primarily affects commercial laying hens and poultry reproduction worldwide, resulting in a 5-10% drop in egg production from affected poultry, and
