How to Disinfect a Chicken House

Disinfection with chicken means that all the articles in the house and the chicken body and space are sprayed with a certain concentration of disinfectant solution. It is an important part of the integrated intensive epidemic prevention of modern intensive chickens, and it is one of the effective means to control the environmental pollution and spread of epidemic diseases in chicken houses. Especially for those poor isolation conditions, it is more effective for different batches of chickens to be raised on the same farm and old chicken farms where various epidemics occur frequently.
First, the role of chicken disinfection
1. It can effectively kill various bacteria and viruses floating in the air in the house, reduce the floating dust in the house, inhibit the production of harmful gases such as carbon monoxide, carbon dioxide and ammonia, and purify the air in the house, thus effectively preventing The occurrence of respiratory diseases in chickens.
2. It can effectively kill a variety of pathogenic microorganisms in chicken houses, prevent the accumulation of pathogens discharged from diseased chickens in chicken houses, and effectively prevent Marek, Newcastle disease, Bursa, Staphylococcus, Escherichia coli, and white peony. The occurrence of other diseases.
Second, the procedures and methods of chicken disinfection
1, sweeping dirt. Clean chicken cages, floors, walls, chicken droppings, feathers, dust, dirt mats, and roof cobwebs as thoroughly as possible.
2, rinse. Flushing with clean water does not kill the pathogenic microorganisms. The purpose is to flush the dirt out of the house and improve the disinfection effect. Rinsing sewage should be drained from the sewer or dark waterway to a remote location and cannot be discharged around the house.
3, careful selection of drugs. The disinfectant must be broad-spectrum, high-efficiency, strong, and less corrosive to metal and plastic products. It has inhalation toxicity, irritation, and skin absorption of humans and chickens, and will not invade residues in meat and eggs. Disinfectants that can be used to disinfect chickens include powerful disinfectants, peracetic acid, benzalkonium chloride, sodium hypochlorite, bactericides, poisonous agents, gold iodine, Huifuxing, and complex phenols.
4, science with liquid. It is better to use tap water to prepare disinfectant solution. The concentration of the disinfectant should be uniform, and the drug that is not easily soluble in water should be stirred thoroughly to dissolve it. When the temperature of the disinfectant liquid is increased from 20°C to 30°C, the efficacy can be increased by 2 times. Therefore, when preparing the disinfectant liquid, dilute it with hot water. However, the water temperature should not be too hot and should generally be controlled below 40°C. The stability of the prepared disinfectant solution deteriorates and should not be stored for a long time. It should be used now and used once.
5, correct disinfection. Disinfection with chicken can make the atomization effect of automatic spray device or agricultural small backpack sprayer, the mist size is controlled at 80-120 microns, the nozzle is about 50 cm from the chicken body is appropriate. When the spray is sprayed upwards, the spray is gradually sprayed inside and outside, and the chickens are sterilized once a day. It is best to sterilize the chicken once every morning and evening. Closed-type henhouses can also use large bottles of peracetic acid, Hui Fuxing and other volatile disinfection drugs hung on the air inlet, with the air into the chicken house, to achieve the effect of chicken house air disinfection.
