Action makes the difference in poultry farms

Viruses attack when we least expect it, and some spread quickly among chickens. This is the case with infectious laryngotracheitis (ILT). It is a viral respiratory disease that affects chickens worldwide. It is caused by Gallid Herpesvirus 1 (GaHV 1), also known as infectious laryngotracheitis virus. An outbreak causes great suffering to the chickens and can lead to severe losses. That is why poultry producers need to have tools to prevent outbreaks from happening

How can I know if my chickens are infected with the ILT virus?

When chickens cough, farmers must be attentive because it can quickly escalate. Chickens could start coughing blood or even die. Additionally, they may display signs of conjunctivitis. Suppose the layer (i.e., egg-laying chicken) is laying fewer eggs than usual. In that case, it can also be an indicator of the presence of the ILT virus.

It is hard to identify the ILT virus based only on symptoms, especially as many signs may also belong to other diseases. Poultry producers need to monitor the incidence of these respiratory signs and contact their veterinarian as quickly as possible. They need to confirm the presence of this viral infection by performing lab tests and necropsy (dissection of a body to determine the cause of death).

What is the best way to prevent the ILT virus?

Good news! There is a way in which farmers can protect their flocks from ILT infections: vaccination.

When chicks have hatched, vaccination is the best way to shield them against this virus. Vaccines can be administered through In Ovo or day-old subcutaneous injection of a vectored HVT (herpesvirus of turkey) vaccine. This application is the most convenient way to start protecting your birds against this imminent threat. Furthermore, live attenuated ILT vaccines may be recommended if they are locally authorized to enhance the level of protection against the infection. They can be applied through an eye drop, spray, and water. These types of vaccines are primarily suitable for pullets (future layers).

But what happens if the ILT virus is already there?

Once the presence of the virus is detected, it is essential to contact your local veterinarian responsible for the farm to contain the situation. They will know how to proceed and can help minimize the impact.

What can farmers do to control the spreading?

ILT travels fast, and it can infect chickens by inhaling it or through the eye. The personnel, farm equipment, and the litter carry the virus, so it needs to be controlled from these different perspectives.

The best thing to do is take action. Several biosecurity measures will help the farmers keep the virus from escalating.
