Today, this paper makes some detailed introduction to the chicken house disinfection procedure, the contents are as follows.

Cleaning and disinfection in chicken coop

The cleaning and disinfection in the chicken house is divided into four steps: "one sweep, two flushes, three sprays and four empty houses".

1. The first step is "sweep". Thoroughly remove and clean up the sundries, chicken droppings, cobwebs and feathers in the henhouse.

2. The second step is "Erchong". Use a clean pump or high-pressure pump to pump water and rinse the chicken house up and down, left and right (and walls, brick posts, windows, floors) thoroughly.

3. The third step is "three sprays". Use clear water pump to disinfect the chicken coop up and down, left and right, until dripping drops, generally every 100 square meters of chicken coop should be sprayed at least 300 jin of water.

4. The fourth step is "four empty houses". After spraying disinfectant, the chicken house should be left vacant for 5 days. After the chicken house is naturally dried, another disinfectant is sprayed, or it is fumigated with potassium permanganate and formalin.

Note: if the chicken coop with bursal disease has occurred, use 5% formalin spray (repeat step 3).

The general disinfection procedure of the chicken house is as follows: after cleaning up the chicken manure, rinse it with water and dry it, sprinkle the ground and 1 meter high wall with 2% caustic soda, rinse with water for 2 days, air dry and then spray with 0.3% disinfectant. After 2 days, spray 0.1% diquaternary ammonium iodide (or 2.8 disinfectant 300 jin) with 0.1% diquaternary ammonium iodide (or 2.8 disinfectant 300 jin) and sprinkle the ground and 1 meter high wall with 20% quicklime for 2 days. Leave 3Mel vacant for 5 days before entering the seedlings.

Disinfection of nursery room

After the completion of the disinfection procedure specified in Article 1, before the chicken house is cool and dry, fumigate with formalin (formaldehyde) potassium permanganate:

1. Formalin: potassium permanganate is 2:1.

2. Per cubic meter of space: 25ml formalin, 12.5g potassium permanganate (spatial cube calculation: length * width * height, unit: meters).

3. Each nursery has 3 porcelain bowls. After putting potassium permanganate into the porcelain bowl, pour in 2 times the amount of formalin immediately.

4. Close and seal the doors and windows of the nursery, and then open the doors and windows for ventilation after 24 hours.
