How to Prevent Aspergillosis in Birds: Methods and Measures

Preventing aspergillosis in birds is an important aspect of maintaining the health of poultry farms and preventing widespread disease. The primary means of preventing this disease is strict adherence to zoohygienic and veterinary sanitary rules during the keeping and feeding of birds.

Key Prevention and Disinfection Measures

To prevent the development of aspergillosis, a comprehensive set of disinfection measures is employed. The wet treatment method involves the use of a 10% solution of calcined soda or a 3% solution of chloramine. Hot solutions of xylonaphth-5 or other fungicidal preparations are also used.

Particular attention is paid to treating premises with a high-dispersion aerosol of formaldehyde. For example, a 40% solution at a rate of 30 ml/m³ or a 25% solution at 50 ml/m³, with an exposure time of up to 6 hours. After treatment, the premises are ventilated, and formaldehyde is neutralized with a 25% ammonia solution, using an amount equal to half the volume of formaldehyde.

Protection of Bedding and Eggs

Before settling the birds, the bedding is treated with a 2-3% solution of copper sulfate (10 ml/m²). Iodoclin is also used for even sprinkling — 50-100 g/m². Before placing the birds, 100 g/m² is used, and subsequently — once a week in the presence of birds — 50 g/m².

During the growing process, birds are inhaled with monochloride iodine at a rate of 0.5 ml/m³, and without birds — 2 ml/m³. Eggs are disinfected three times:

• no later than 1-1.5 hours after laying;
• before placing in the incubator;
• after transferring to the hatching cabinets.

For the first two procedures, a high-dispersion aerosol of a 35% formaldehyde solution is used at a rate of 40 ml/m³ or a 38-40% solution at 25 ml/m³ for 30 minutes. The third disinfection involves using an aerosol of a 33% solution of iodotriethylene glycol at a rate of 15 ml/m³.

Additionally, the bedding is disinfected with solutions, including a 4% solution of peracetic acid, sodium or calcium hypochlorite, and chloramine B (with active chlorine 2%) — 600 ml/m², and paraform — 0.5 kg/ton of bedding.
