What is Chronic Respiratory Disease (CRD)?
Chronic Respiratory Disease (CRD) is a common respiratory disease found in poultry, especially in chickens. The disease can be caused by a bacteria called Mycoplasma gallisepticum, which affects the respiratory system of the bird, leading to chronic respiratory problems.

CRD is caused by a bacterial infection called Mycoplasma gallisepticum, which is highly contagious and can spread rapidly from one bird to another. The disease can be transmitted through contact with infected birds, contaminated equipment, or even through the air.
The signs of CRD in poultry include:
- difficulty breathing
- nasal discharge
In severe cases, the bird may exhibit a gasping motion and its beak may become swollen and discoloured.
The symptoms of CRD in poultry include:
- respiratory distress
- laboured breathing
- loss of appetite
- decreased egg production
in severe cases, death. The symptoms may take a few days to develop after infection and can last for several weeks.
Preventing CRD in poultry is crucial to ensure the health of the flock. The following preventative measures can be taken:
- Quarantine infected birds
- Use proper biosecurity measures
- Clean and disinfect equipment regularly
- Provide a well-ventilated environment
- Avoid overcrowding
Chronic Respiratory Disease is a common respiratory disease in poultry caused by a bacterial infection called Mycoplasma gallisepticum. Early diagnosis and treatment are crucial for successful recovery and preventative measures can be taken to reduce the risk of infection.
Q: How long does it take for CRD to spread to other birds?
A: CRD is highly contagious and can spread rapidly to other birds within a flock. The incubation period for CRD is typically 2-4 weeks.
Q: What causes chronic respiratory disease in chickens?
A: CRD is caused by a bacterial infection called Mycoplasma gallisepticum, which is highly contagious and can spread rapidly from one bird to another.
Q: How do you treat CRD in chickens?
A: CRD can be treated with antibiotics such as tetracycline or oxytetracycline. However, treatment is more effective when administered early in the infection. In severe cases, euthanasia may be necessary to prevent the spread of the disease.
Q: What are the symptoms of chronic respiratory disease in poultry?
A: The symptoms of CRD in poultry include difficulty breathing, coughing, sneezing, nasal discharge, respiratory distress, wheezing, labored breathing, loss of appetite, decreased egg production and in severe cases, death.
Q: What is the best drug for CRD in poultry?
A: Tetracycline or oxytetracycline are commonly used antibiotics to treat CRD in poultry.
Q: Can chickens recover from respiratory disease?
A: Yes, with early diagnosis and treatment, chickens can recover from respiratory diseases. However, in severe cases, the bird may not recover and euthanasia may be necessary.
Q: What medicine can I give my chickens for respiratory infection?
A: Antibiotics such as tetracycline or oxytetracycline are commonly used to treat respiratory infections in chickens.
Q: Is there a vaccine for CRD in chickens?
A: Yes, there are vaccines available to prevent CRD in chickens. Vaccination is recommended for all birds in a flock, especially those at high risk of infection.
Q: Can humans contract CRD from infected birds?
A: While it is possible for humans to contract Mycoplasma gallisepticum from infected birds, it is very rare and the infection is generally mild and self-limiting.
Q: How long does it take for a chicken to recover from CRD?
A: The recovery time for a chicken with CRD can vary depending on the severity of the infection and how quickly it is diagnosed and treated. Some birds may recover within a few days, while others may take several weeks to recover fully.
Q: Can CRD be transmitted through eggs?
A: No, CRD cannot be transmitted through eggs. However, infected birds may pass the bacteria to their offspring during hatching, resulting in chicks that are already infected with the disease.
Q: What should I do if I suspect CRD in my flock?
A: If you suspect CRD in your flock, isolate the affected birds immediately and contact a veterinarian for diagnosis and treatment. It’s also important to take preventative measures to reduce the risk of further spread within the flock.
Q: How can I prevent CRD in my flock?
A: To prevent CRD in your flock, practice good biosecurity measures, such as quarantining new birds, keeping equipment clean and disinfected and avoiding overcrowding. Vaccination is also recommended for all birds in the flock, especially those at high risk of infection.
