Precautions For Fumigation And Disinfection Of Chicken Coops

Precautions for fumigation and disinfection of chicken coops

Among chicken house disinfection methods, chicken house fumigation disinfection is one of the common and thorough disinfection methods. Moreover, chicken house fumigation disinfection can effectively disinfect the ground, crevices, breeding equipment and electromechanical equipment in all directions. In order to ensure the effect of fumigation and disinfection of chicken houses, what are the precautions in the process of fumigation and disinfection of chicken houses?

One, the container should be ready

Both formalin and potassium permanganate are corrosive. The chemical reaction that occurs when they mix is ​​violent, lasting 10 minutes to 30 minutes, and releasing a lot of heat. Therefore, the volume of the container containing formalin and potassium permanganate should be as large as possible, generally not less than 4 times the volume of formalin, and it is best to be corrosion-resistant and heat-resistant ceramic or enamel containers.

Second, the medicine should be appropriate

The concentration of formalin used for fumigation and disinfection shall not be less than 35%, and the mixing ratio of it and potassium permanganate shall be 2:1. Whether the mixing ratio of formalin and potassium permanganate is appropriate can be judged according to the color of the residue after the reaction and the degree of dryness and wetness: if it is some slightly wet brown powder, the ratio is appropriate; if it is purple, it indicates high manganese The dosage of potassium acid is too large; if it is too wet, the dosage of formalin is too large.

3. Proper operation

The disinfection container should be evenly placed in the chicken house, and as close as possible to the door of the house, so that the formaldehyde gas can better permeate the entire chicken house space and facilitate the staff to evacuate quickly after the operation. During operation, the staff should first put potassium permanganate into the disinfection container, and then pour it into formalin proportionally. It is absolutely forbidden to put potassium permanganate into formalin. Fumigation and disinfection of empty houses can only be carried out on brooding rooms, chicken houses after transfer, and chicken houses that have been vacant for a long time.

Fourth, the odor should be eliminated

Before fumigating and disinfecting the chicken house, all doors and windows should be opened for ventilation for more than 2 days to remove the formaldehyde gas. If you need to use it urgently, first use 5 grams of ammonium bicarbonate, 10 grams of quicklime, and 10 milliliters of hot water at 75°C per cubic meter of space. Put them in a disinfection container and mix them evenly. Use the ammonia gas generated to neutralize the formaldehyde. Air for 30 minutes, and finally open the doors and windows of the chicken house to ventilate for 30 to 60 minutes.

Five, the environment should be suitable

When performing fumigation and disinfection, it is also required that the temperature in the chicken house is not lower than 18℃ and the relative humidity is above 60%. In order to meet the above requirements, the temperature can be maintained at 18℃~26℃ by heating in a stove in the chicken house, spraying clean water with a sprayer or adding 6 grams of potassium permanganate per cubic meter of space with 6ml-9ml of clean water ~9g method, the relative humidity will rise above 60%.

Sixth, clean up thoroughly

The penetrating ability of formaldehyde gas is weak, only the surface disinfection effect. Therefore, before fumigation, the feces, dust, cobwebs, feed residues and other debris on the floor, walls and ceiling of the chicken house must be thoroughly cleaned, and then washed with a high-pressure spray water gun to ensure that the chicken house Any place is spotless, so that the use of formaldehyde gas can fully contact with pathogenic microorganisms such as viruses, spores, bacteria and bacterial propagules.

The important thing is that the chicken house should be sealed. The effective medicine for fumigation and disinfection of the chicken house is formaldehyde gas. The higher its concentration in the chicken house and the longer the residence time, the better the disinfection effect. Therefore, before fumigation and disinfection, all doors, windows, walls and gaps in the chicken house must be sealed with plastic film or tape; after fumigation and disinfection, they must be sealed for more than 1 day.

The advantage of the fumigation and disinfection method of the chicken house is that the fumigated drug gas can be evenly distributed to all corners of the chicken house to cut off the spread of pathogens. Do mechanical removal before disinfection, to give full play to the role of disinfection drugs, the drugs must be in direct contact with pathogenic microorganisms, etc. Therefore, fumigation and disinfection of chicken houses should maximize the sterilization effect under the premise of ensuring safety.
