How to do a good job of disinfection of empty houses in farms 20

Top the second floor, but the first floor method should also be tried.

, 20%-30% plant ash (mainly containing potassium carbonate): take 10-15 kg of sieved plant ash, add 35-40 kg of water and stir evenly, continue to boil for 1 hour, and make up the evaporated water. It is mainly used for disinfection of enclosures, sports fields, walls and troughs.

It should be noted that the water temperature is best at 50°C-70°C.

-20% lime milk (calcium hydroxide): take 5 kg of quicklime and add 5 kg of water, wait for it to be turned into paste, and then add 40-45 kg of water. It is used for the disinfection of enclosures and venues, ready to use, and stirred evenly.

Proper selection of disinfectants Farmers should use disinfectants recommended by the local veterinary epidemic prevention department according to different disinfection objects, requirements and environmental conditions. Check its label and instructions when purchasing to determine whether it is a qualified and valid disinfectant approved by the veterinary drug regulatory department for production and sale. At the same time, consider whether the disinfectant has the best inexpensive, soluble in water, no residual toxicity, no damage to the disinfectant, relatively stable in the air, easy to use, and has a broad-spectrum, rapid and efficient disinfection effect on the prevention and extinguishing of epidemic diseases.

In use, scientific preparation methods are adopted as required. According to the requirements of the instruction manual, the actual required concentration, appropriate temperature and solvent selection should be prepared, and the agent should be prepared and used immediately, and should not be stored for a long time; Some disinfectant solutions are prepared for multiple uses at one time, but the content of active ingredients should be determined first, and prepared and used according to the measurement results.

Second, the disinfection method should be appropriate According to the specific conditions of different disinfection environments, disinfection objects and types of disinfectants, etc., the disinfection methods that can produce efficient and feasible disinfection methods can be selected. Generally, spraying, infiltration, drinking water, fumigation, etc. In addition, there are disinfection methods such as flame, high temperature, cooking, and biological fermentation.

In production, scientific disinfection procedures should be designed, and compatibility contraindications should be avoided when two or more varieties of agents are used together. When disinfection, use the diluted disinfectant to disinfect directly, and after a certain period of time, remove the dirt on the disinfectant, especially the organic matter. Repeat the disinfection with disinfectant again, so that the operation effect will be better.

Long-term use of disinfectants should be cross-medicated, and large doses or long-term use of the same disinfectant should be avoided, otherwise, it is easy to develop drug resistance, and even cause environmental pollution and excessive drug residues in animal products. Therefore, cross-medication must be used on a case-by-case basis during production. 3. Preventive disinfection should pay attention to preventive disinfection Preventive disinfection can play a role in epidemic prevention and control.

Disinfection should be carried out regularly according to local conditions. Although sometimes no epidemic occurs, if the environment is not disinfected and purified in time, the pathogens in the environment will accumulate more and more, and the number and virulence of pathogens reach a certain level, and epidemics are prone to occur. At the same time, there will be blind spots in disinfection and transmission through the air, wild birds, rats, the surrounding environment, trees, etc., which is also a threat.

Therefore, different disinfectants and disinfection methods should be selected according to different disinfection objects for disinfection of vehicles, personnel and articles, enclosure places, utensils, etc.

The farm is disinfected daily, so that bacteria and viruses can be quickly disinfected.

Under normal circumstances, the farm does not need to be disinfected, and it is enough to clean and hygienize regularly.

In the event of an animal infectious disease in or near the local area, necessary disinfection measures should be taken as appropriate. When disinfection, disinfectants such as 84 disinfectant or bleaching powder supernatant can be used to wipe or spray disinfection on guardrails, walls, floors, etc.; For wet ground, it can also be directly sprinkled with bleaching powder or quicklime; For livestock and poultry manure, a chlorine-containing disinfectant solution containing 10000 20000mg l of available chlorine can be added, mixed and placed for 2 hours.
