What disinfectant is used for cattle pen disinfection? What is the best disinfectant to use for catt

Disinfectant for cattle pen disinfection:

1. Caustic soda: When using caustic soda to disinfect the cattle pen, it should be noted that because caustic soda has a corrosive effect on metal objects, it must be rinsed with water after disinfection. Moreover, caustic soda has a strong corrosive and damaging effect on **, coat and clothing, so you should pay attention to protect yourself when using it.

When disinfecting the barn, all the cattle must be removed, and after disinfection, the diaphragm should be used for half a day to rinse the ground and feeding trough with water, and then the cattle can be put into the pen.

2. Grass ash.

You can use 10-15 kg of fresh and dried plant ash, add 50 liters of water, boil for 20-30 minutes, stir while cooking, and then remove the slag to use. Grass ash can generally be used for floor disinfection, and its main ingredient is potassium hydroxide.

or potassium carbonate, the disinfection effect is the same as 1%-2% caustic soda.

3. Formaldehyde: You can also use 2%-5% formaldehyde to carefully disinfect the ground, utensils, walls and excrement of the cattle pen, and you can choose to spray and fumigate when using. Generally, 1 cubic meter volume is filled with 25 ml of formaldehyde plus the same amount of water, and then heated to volatilize it into gas, or 25 grams of potassium permanganate are added.

Fumigation and disinfection.

Classification of disinfection effect.

Highly effective disinfectant: refers to one that can kill all bacterial propagules (including mycobacteria).

Viruses, fungi and their spores, etc., also have a certain killing effect on bacterial spores (pathogenic spores) and meet the requirements of high-level disinfection.

Medium-effect disinfectant: refers to the preparation that can kill microorganisms such as mycobacteria, fungi, viruses, and bacterial propagules to meet the disinfection requirements.

Inefficient disinfectant: refers to the preparation that can kill bacterial propagules and lipophilic viruses and meet the disinfection requirements.

Because there is no contamination of infectious disease pathogens, the newly built cattle pen generally only needs to be cleaned and cleaned without deliberate disinfection. If disinfection is really necessary, it can be sprayed with 84 disinfectant, and the ground can also be sprinkled with bleaching powder or quicklime.

There is no need to disinfect, just clean up as usual. If a zoonotic disease occurs locally or nearby, the tongue should be disinfected. For walls, railings, floors, etc., 84 disinfectant or bleaching supernatant can be used for spraying or wiping disinfection, and damp ground can also be directly sprinkled with quicklime or bleaching powder.

Precautions for the use of household disinfectants.

Reasonable allocation of concentration of chemical disinfectant can only reach a certain concentration to have a disinfection effect, the concentration is too low can not eliminate pathogenic microorganisms, too high concentration may have a significant destructive effect on the disinfection object, and may bring harm to human health. The higher the concentration of disinfectant, the better.

When the cattle farm needs to be disinfected, it is recommended to use chlorine-containing preparations such as 84 disinfectant and bleaching powder. Chlorine-containing disinfectants are highly effective disinfectants that can effectively kill common bacteria, viruses and other pathogenic microorganisms.

Disinfection refers to the method of killing pathogenic microorganisms, but not necessarily bacterial spores. Chemical methods are usually used to achieve the effect of disinfection. The chemicals used for disinfection are called disinfectants.

Sterilization refers to the method of killing all microorganisms on an object, usually using physical methods to achieve the purpose of sterilization.

Preservative refers to the method of preventing or inhibiting the growth and reproduction of microorganisms. The chemicals used for embalming are called preservatives. Sterile means no live bacteria and is the result of sterilization. The technique of preventing microorganisms from entering the body or objects is called aseptic operation.

Significance of disinfection:Prevent the spread of pathogens into society and cause epidemics.

Prevent patients from being infected by other pathogens, complications, and cross-infection.

It also protects healthcare workers from infection.

Types of commonly used disinfectants.

1) Quicklime: Paint walls and floors with 10%-20% emulsion, and use and prepare ready, 2) Lysol (coal phenol soap solution): ineffective for spores, disinfect hands and instruments with 1%-2% solution. 4%-5% solution to disinfect stables and transport vehicles.

3) Sodium hydroxide: also called caustic soda or caustic soda. It has a strong killing effect on bacteria and viruses, and increasing the concentration can kill spores.

The concentration can be used for virtual body disinfection and indoor spraying, and the concentration of 2%-3% is generally used for disinfection.

4) New Gil Kill: Disinfect hands, ** and sterilize instruments with concentration.

5) Nongle (bacteria and viruses): effective against bacteria and viruses, with a concentration of 1%-2% for the disinfection of contaminated livestock houses, sites and means of transportation.

Disinfection is aimed at pathogenic microorganisms, and in general, the possibility of contamination of the cattle pen by pathogenic microorganisms is very small, so there is no need for disinfection, and regular cleaning and hygiene can be done.

If contamination of the pen is confirmed or suspected to be contaminated with pathogenic microorganisms, or to prevent infection before and after the cow farrowing, it is necessary to disinfect the barn. For disinfection, chlorine-containing disinfectants (such as 84 disinfectant, bleaching powder supernatant...... can be usedPeracetic acid and other disinfectants to spray and disinfect fences, walls, etc. The above-mentioned disinfectants are all high-efficiency disinfectants, which can effectively kill common bacteria, viruses and other pathogenic microorganisms.

For wet ground, bleach can be directly sprinkled.

There are many types of disinfectants used in the cowshed, and the concentrations are also different, so the commonly used disinfectants and concentrations are introduced as follows.

Brush the barn, walls and floors with quicklime water, and wait until the quicklime water is dry before laying straw and feeding the cattle.

After the barn has been disinfected, how long does it take for the cattle to enter the barn?

1.Mechanical removal method: It mainly removes pathogens through mechanical methods such as sweeping, scrubbing, ventilation, and filtration. Although this method is common and commonly used, it cannot achieve the purpose of thorough disinfection, and as an auxiliary method, it must be carried out in conjunction with other disinfection methods.

2.Physical disinfection: sunlight, ultraviolet rays, drying, high temperature, steaming and other methods are used to kill bacteria and viruses. _

3.Chemical disinfection: The most commonly used method is to use chemical drugs to kill and imitate pathogens.

The selection of disinfectant drugs should consider sterilization broad-spectrum, low effective concentration, fast action and good effect; second, it is harmless to humans and animals; Third, the properties are clear and stable, soluble in water, and not easily affected by organic matter and other physical and chemical factors; Fourth, it is easy to use, inexpensive and easy to promote; Fifth, it is tasteless, odorless, and does not damage the disinfected items; Sixth, the residual amount after use is small or small. __

4.Biological disinfection method: This method is commonly used to accumulate and ferment contaminated feces, and use thermophilic bacteria to produce heat of more than 70 when multiplying, and can kill pathogens such as viruses, bacteria, and parasite eggs after 1 or 2 months.

However, this method is not applicable to diseases caused by spore pathogens such as anthrax and emphysema, and the feces of such diseases should be burned or buried deeply.
