Diagnosis of chicken often respiratory disease – Amouns prevention and control – China Animal Husbandry Website – A useful animal husbandry website

In recent years, with the development of the aquaculture, the development of epidemic chicken disease is increasing. In popular chicken disease, chicken respiratory disease is a key disease that threatens the healthy production of chicken industry. It is more common, and symptoms are similar, mostly mixed infections, difficult to prevent treatment, seriously affect the growth and development of chickens, bring huge gains to farms Economic loss. How to effectively determine the nature of respiratory disease and formulate prevention and control programs, is one of the top probables of many clinic veterinarians.

Overview: Newcastle disease is also known as Asian chicken or chicken fever, is a poultry height contact with poultry caused by a new city disease. Each aged chicken is susceptible. Non-immunized chickens will have extremely high incidence and mortality. The clinical symptoms are mainly characterized by elevated body temperature, loss of appetite, yellow-green dung, spirit and depth, show different levels of respiratory symptoms (cough, snoring, Zhangqi, breathing, etc.). Oduumic chickers showed a decrease in laying, and the white-shell eggs were produced, and the abnormal eggs were produced. Various neurological symptoms (twist, wings paralysis, etc.) can occur later. Typical cutting diseases are mainly duodenal near-end, ileum starting portions, more common partial mucosa congestion swelling or purple jujube nucleus ulcers. Tonsil swelling, bleeding, adentective nipple bleeding. Outlot hiopsis visible follicles, bleeding, deformity, liquefaction. Tracheal bleeding, with mucus.

Establish and improve the hygiene and epidemic prevention system; after the disease, it must be blocked immediately, isolate the pathogenesis, and thoroughly disinfected; the dead chicken body and feces , Stepping, etc. should be incinerated, deeply involved in disinfection. Technical Consultant: Wang Xiao Consultation: 15725217809 (with VX Cong) hopes to talk to everyone to talk about chicken knowledge.

Infectious bronchitis is an acute and highly contactive infectious disease caused by infectious bronchitis virus. Chicken is the only natural host of this disease. Various aged chickens are susceptible, but the sick is seriously ill. In the early days, slight respiratory symptoms, such as the sound, sneeze, cough, etc., but only when quiet is quiet. The chicken suddenly has a large number of incidence, gradually intensifies, showing anorexia, thirst,Spiritual loss, arch back, drainage, white dung, feces contain a large amount of uric acid salt, surrounding feathers around the anus, dirty sickness, hardening, severe face and full body skin color dry, hardcore Ministry dry. Typical Cayage Symptoms: The kidney is swollen, pale, and the appearance of the anthrophone. The appearance is extremely thin, the detection of the visible adenopsis is extremely swollen, and the spherical swelling is large.

Prevention and control measures

Strengthen feeding management. Adhere to the whole process, strictly sanitary disinfection measures, thoroughly cleaning and disinfection in front of the whole audience, and regularly with chicken in the next child, pay attention to reduce the stimulation of the chicken respiratory mucosa, avoiding adverse stress; with the growth of the egg And seasonal changes, reasonable reduction of feeding density, pay attention to temperature, humidity, avoid climate environment stress; chicken should pay attention to ventilation, especially in autumn and winter, the time is longer, to prevent harmful gas concentrations from exceeding the standard, trigger chicken Branch; give high-quality full-price feed, guarantee adequate cleaning water, reasonable application of vitamins, especially vitamin A, vitamin E, vitamin C can be doubled, appropriate amounts of minerals and maintain balanced; this disease recovery chicken is forbidden As a chicken, the eggs cannot be seeded.

Infectious laryngi

Overview: infectious laryngi is an acute respiratory infectious disease caused by infectious laryngonia virus. A variety of chickens can be infected, and adult chickens are most features. In the winter and spring season, the disease rate and the mortality rate are high. This disease is characterized by difficulty breathing, cough and coughing from blood-containing mucus, laryngeal and tracheal mucosa, bleeding – necrotic inflammation. It is mainly divided into laryngiitis and conjunctivitis. Latutani is inflammatory: feature is that the diseased chicken is characterized by difficulty breathing, looking up the neck, coughing, coughing, and coughing. Corry-checking lesions are swollen laryngeal and tracheal mucosa swelling, congestion, bleeding, or even necrotic, and intracorinum cavity often filled with blood clots, mucus, pale yellow cheese exudates. Conjunctiva: Mainly slurry conjunctivitis, showing edema, congestion. Some chicken eyes, especially the face of edema. Some will have celluloseclic conjunctivitis, corneal ulcers. Sometimes mixed with laryngeal, tracheal lesions.

Prevention and control measures

Strengthening feeding management, reducing feeding density, preventing pathogenic invasion, once the pathogenesis, viruses are not easy to eradicate. Pay attention to the disinfection and hygiene of the chicken house, can be disinfected with disinfectants, 2 to 3 times a week, and pay attention to the insulation of the chicken house. The chicken farm that has undergone this disease is the most effective preventive measures to vaccine immunity. The egg hooks and seeds were applied to the vaccine drop 2 times before and after 40 days before and after 80 days, and the disease can be effectively prevented. At the same time, it is recommended to immunize 4 to 5 days, the chicken house is sterilized in time, and the chicken can effectively prevent the chicken from tearing, nasal and other vaccines.

Infectious rhinitis is a chicken acute upper respiratory disease caused by the elderly vice, with nasal cavity and sinus inflammation, flow Nose, sneezing, facial swelling and adult membrane is the main probation symptom. The chickens of any age are prone, but young chickens are generally less serious. The 8 ~ 12 weeks old chickens are most common. Most of the season occurred in autumn and winter. Typical cases, tatone diseases become slurry, mucus or suppurative inflammation of nasal cavities, sinus and eye-catching membranes. Visible sinus, yellow, viscous purulent secretions or cheese samples, sinus prostate or cheese samples, sullen respiration symptoms and constant heads.

Prevention measures

First strengthen feeding management. The chicken house must be well ventilated, and the chicken group should not overcrowly, prevent various stress.

Overview: Chronic respiratory tract is a chronic respiratory pathogen caused by chicken infection, the clinical is mainly manifested as cough, runny nose, and breathing. Chronic respiratory disease characterized by gasping, sinus swelling, color swelling. Although the mortality rate is low, the chickens are slow, and the laying egg declines, and the feed pay is low. Available in four seasons in the year, the climate is more variable and the cold season has been sent. The tangible symptoms have a large number of viscous secretions in the nasal cavity, trachea. Early airbags mild turbid edema, opaque, as the disease progresses, forming a cheese-like substance on the airbag. Always mixed with viral diseases and other bacterial diseases, such as E. coli, avian influenza, new city disease, infectious bronchTannitis, etc. The chicken environment should be good in the honeyhouse to maintain a good ventilation, reduce the concentration of harmful gas, and the sun is sufficient in the chicken. It is necessary to clear the fecal debris and regular replacement of the gasket, and do a good job in keep warm, and the density of feeding is reasonable to prevent crowding. What should I do if I have a new city evolution, a disease of new city disease? What should I do if I get a respiratory tract?
