What are the precautions for fumigation disinfection of chicken coops?
Chicken coop disinfection is a task everyone will definitely do during the breeding process, and there are many methods of chicken coop disinfection. Fumigation disinfection is one of them. Fumigation disinfection is a relatively common disinfection method and is also the most basic method of disinfecting empty coops. However, there are some aspects of fumigation disinfection that we need to pay attention to. If it is not managed well, it will not only have a certain impact on the growth of the chickens, but may even harm human health. Now let's take a look at the precautions for fumigation disinfection!
1. Clean thoroughly
After the broiler chickens are sent to market and before fumigation disinfection, the chicken coop must be comprehensively cleaned, including the walls, ceiling, and so on. Manure, leftover feed, and all kinds of things that do not belong in the chicken coop must be completely removed. Then use clean water to spray and wash everything, without missing any corner, and the feeding equipment and daily tools in the chicken coop must also be cleaned thoroughly. This prevents reducing the effect of fumigation disinfection, because fumigation disinfection uses a disinfectant in gas form to disinfect. If the chicken coop is too dirty, then the area covered by the gas is reduced, leading to a lower disinfection effect.
2. Seal the chicken coop
As just mentioned, the form of fumigation disinfection is gas disinfection, so during disinfection the chicken coop must be sealed to reduce ventilation. If conditions allow, it can be placed in a completely airtight environment. Moreover, the main disinfectant is formaldehyde, and the disinfection effect of formaldehyde is directly proportional to its concentration and time. Therefore, during disinfection, apart from keeping one door for the feeding staff to enter and exit, all other vents and windows and doors must be sealed off to prevent gaps from letting air leak through and reducing the effect of fumigation disinfection. In addition, formaldehyde is also harmful to the human body, and this can prevent it from escaping the chicken coop and affecting people's breathing.
3. Prepare containers
Before disinfection, containers should be prepared according to the area of the chicken coop. If the chicken coop is large and the dosage of disinfectant used is relatively high, at least more than one container should be prepared. This is because if too much disinfectant is used, it is very easy for the liquid to overflow, causing waste of the disinfectant and increasing disinfection costs. The containers should have sufficient volume and be suitable for holding the full amount of disinfectant. The containers should also have a certain resistance to corrosion and heat, because the disinfectant has a certain corrosiveness and the temperature is relatively high. If they cannot withstand it, the disinfectant will also be wasted.
4. Remove odors
Because the disinfectant used in fumigation disinfection is formaldehyde, and formaldehyde has a very strong smell, after disinfection we should promptly open the vents for ventilation and air exchange to discharge the formaldehyde odor and reduce the formaldehyde concentration. Formalin residue must not be left behind, to prevent the chickens from accidentally eating it and being poisoned. Before the chickens enter the coop, the formaldehyde odor must be completely removed, otherwise it will affect the growth of the chickens. If it is not completely removed, it will lead to uneven growth progress in the flock, reduce the early growth rate, delay the time of sending them to market, and also affect the effectiveness of vaccines.
The above is a brief introduction to the precautions for fumigation disinfection of chicken coops. Fumigation disinfection is relatively comprehensive and thorough. However, if management measures are not done well, it can very easily harm the growth of the flock and may even threaten human health. Therefore, everyone must do the preparation work before disinfection to reduce the harm. That is all for today's introduction. This article is for reference only. Thank you for reading and supporting.
