Treat coryza in chickens, cold in birds is a severe bacterial infection found in an acute form, it affects the upper respiratory tracts in chickens and is characterized by the presence of inflammation of the eyelids, water secretions from the nose and eyes, swelling of the sinuses with edema, swelling in the face and sneezing, and sometimes a little in the lower respiratory tract, inheritance Prolonged disease is often accompanied by mycoplasma and coliform infection.
What is coryza in chickens
Coryza causes a bacterium called Haemophilus bargainer, a microbe that is susceptible to heat and kills it at a temperature of more than 50 ° C within 5 minutes.
The disease increases in severity and remains for the flock during the cold winter months. The severity of the disease also increases if the bird is exposed to weak factors such as poor ventilation, increased humidity in the wards, severe crowding, lack of feed quantities, and lack of vitamins, especially vitamin (A).
The severity of the infection varies according to the virulence of the microbe or the presence of accompanying secondary infection. Chickens are the only bird exposed to infection under natural conditions, and it is exposed to the disease at all ages. However, older ages are more susceptible to disease, and disease always appears in intensive breeding.
The infection is transmitted by inhaling air contaminated with nasal secretions from infected birds and through the mouth by eating contaminated food and water. The infection spreads through the horizontal and mechanical paths through the tools and utensils used in the infected wards.
How to prevent coryza in chickens
Sources of infection are always infected birds that have recovered from Recovers disease.
