Early spring chicken infectious laryngotracheitis should pay attention to, how to treat what drugs you need to know!

Infectious laryngotracheitis is an acute and contagious upper respiratory infectious disease caused by infectious laryngotracheitis virus. So here to remind the majority of farmers, early spring chicken infectious laryngotracheitis should pay attention to, how to treat what drugs you need to know!

What medicine does chicken infectious laryngotracheitis use?

Can be used Gankang polypeptide, each set can be injected 1000 adult birds, 2000 chicks, generally once injection. Drinking water each set of 500 adult birds, 1000 birds concentrated 3 Mel 4 hours to drink, generally drinking water once, seriously ill drinking water for two days, once a day.

Note:

1. Avoid mixed use of Gankang polypeptides and strong acid and strong base drugs.

2. Gankang polypeptide is not a special case without additional dosage.

3. 50 minutes after taking the drug, there will be detoxification (diarrhea), and it will disappear the next day.

How to treat it? What are the prevention and control measures?

Spring is a disease-prone season. Infectious laryngotracheitis is an acute respiratory infectious disease caused by herpesvirus. The disease spreads quickly and the mortality rate is high. It can happen all the year round, but it happens frequently in winter and spring.

In the initial stage, the diseased chicken had nasal juice, translucent, tears in the eyes and conjunctivitis. It was followed by characteristic respiratory symptoms, that is, wet rales, coughing and wheezing. Inhale head and neck forward, upward, open mouth, inhale difficulty, there is wheezing sound. Severe cases, high dyspnea, cough, coughing with blood mucus. Secretions can be asphyxiated to death when they can't cough and block the trachea.

When the disease occurs, it can be treated symptomatically, and antibiotics are used to prevent secondary infection. Disinfect chicken sheds and raising utensils frequently. Chickens can be immunized with attenuated vaccine by electric eye in the endemic area of the disease. The time of the first immunization was about 4 weeks old, and the second immunization was carried out after 6 weeks. Diseased chickens can be injected intramuscularly with 50-100000 units of streptomycin twice a day for 3-5 days. The virus spirit is mixed and fed.

Measures:

Treatment

Prevention of chicken infectious laryngotracheitis attenuated vaccine 1 dose of usage: 30-day-old eye drops, nasal drops. Note: as vaccination can make chickens carry virus, this prescription is only used in areas where the disease is endemic.

When you get sick, you can use Longda tripeptide and each set can inject 1000 adult birds. Antimicrobials were used to prevent secondary infection. Breeding and management equipment and chicken sheds should be disinfected. Sick chickens should not be raised in mixed herds with susceptible chickens.

Disinfection

Raise and manage appliances and chicken sheds for disinfection. Chickens of unknown origin should be isolated and observed, and several susceptible chickens can be put together with them. Observe for 2 weeks, do not get sick, prove that there is no virus, then you can mix and raise.

Elimination

Sick chickens can not be raised in mixed groups with susceptible chickens, and tolerant recovered chickens carry virus and detoxification within a certain period of time, so it is necessary to strictly control the contact between susceptible chickens and recovered chickens, and it is best to eliminate sick chickens.

Immunity

Chickens naturally infected with infectious laryngotracheitis virus can produce strong immunity, which can be obtained for at least 1 year, or even lifelong immunity. The protective effect of susceptible chickens can range from half a year to one year after vaccination. Maternal antibody can be transmitted to offspring through eggs, but its protective effect is very poor, and it does not interfere with chicken immunization, because the vaccine virus belongs to cell-bound virus. The authors believe that it is best not to be immunized with attenuated vaccine or natural virulent vaccine in areas where the disease is not endemic, which can not only make the epidemic source of the disease exist for a long time, but also spread other diseases.

Vaccination

In the areas where the disease is endemic, you can consider vaccinating chicken infectious laryngotracheitis attenuated vaccine, nasal drops, eye drops (also with drinking water) immunity. Follow the instructions for use of the vaccine.
