Requirements for the Use of Disinfectant Sprays on Poultry Farms

Today, poultry farming has entered an intensive and large-scale stage, but the outbreak of diseases brought about by intensive farming and the rapid spread followed. In order to cope with this situation, farmers have used Various methods, disinfection is an important part of them.

Disinfection is divided into several forms, including factory environment disinfection, surface disinfection, disinfectant spray, immersion disinfection, etc. Nowadays, most large-scale farms can perform basic disinfection procedures, but spray animal facility disinfectant is used by many. ignored by breeders.

Ⅰ. Why is a disinfectant spray necessary?

1. The disinfectant spray can effectively kill pathogenic microorganisms in the poultry house during the breeding process, reduce their content, greatly reduce the chance of poultry contacting pathogens, and control the spread of diseases.

2. Some acidic disinfectant sprays can neutralize the ammonia gas in the poultry house and reduce the dust content in the air at the same time. The disinfectant spray reduces the irritation of ammonia gas and dust particles to poultry.

3. In hot summer, the disinfectant spray can promote evaporative heat dissipation and play an effective cooling role.

Ⅱ. Several precautions for the disinfectant spray

1. Cold stress

The veterinary disinfectant spray can increase the humidity in the poultry house, and the evaporation of water can take away a lot of heat, which is easy to reduce the temperature in the poultry house in a short time, causing cold stress.

Solution:

(1) Administer vitamin C or multivitamin to poultry before disinfecting spray.

(2) Appropriately increase the temperature in the poultry house before spraying (2 to 3 °C higher than the conventional temperature)

2. Selection of disinfectant spray types

The disinfectant spray should be as efficient, safe and less irritating as possible, such as quaternary ammonium salt disinfectant spray, iodine preparations, chlorine preparations, potassium hydrogen persulfate compound and other disinfectant sprays.

The choice of disinfectant spray should also consider the age of the flock, the disinfection environment, the epidemic characteristics of infectious diseases, etc., and select the corresponding disinfectant spray in a targeted manner to achieve a better disinfection effect.

3. Spray time

The spraying time should be as high as possible at noon, and at the same time reduce the brightness of the light to prevent the flock from being overly frightened and causing stress.

4. Dilution of the disinfectant spray

The dilution ratio of the disinfectant spray refers to the manufacturer's recommendations. The best dilution water is tap water or well water. There are fewer impurities in the water and less impact on the disinfectant spray.

In winter, the temperature is low, and warm water (about 30°C) should be used when diluting the disinfectant spray. On the one hand, it can improve the disinfection effect of the disinfectant spray, and on the other hand, it can also prevent the flock from being stimulated by cold.

5. Control the spray particle size

During disinfection, the particle size of the droplets needs to be controlled between 80 and 120 microns, and the minimum cannot be lower than 50 microns to prevent respiratory problems caused by too small droplets. If the droplet is too large, it will cause uneven disinfection and excessive humidity in the poultry house after disinfection.

6. Disinfection is not recommended before and after vaccination

For vaccine immunization, especially 3 days before and after bacterial vaccine immunization, using the disinfectant spray for poultry farm should not be done, so as not to affect the immune effect. At the same time, doing so also avoids the double stress caused by immunization and spray disinfection.

7. Disinfection operation

The sprayer or dilution bucket must be cleaned. When disinfecting, the spray head of the disinfection sprayer should face upwards to make the droplets fall evenly. Pay attention to spraying on the ground, walls, ceilings, cages, etc. to moisten the ground, walls, and cages. The body surface should be slightly damp.

After spraying, ventilate as soon as possible to let the water evaporate as soon as possible. After disinfection, thoroughly clean the spray equipment, and do not let the disinfectant spray remain in the spray equipment.
