Disinfection methods and points for attention of Lime in Pig Farm

Pig farm disinfection is one of the most important work of raising pigs, it is related to the health of pigs, and in disinfection is the most commonly used timely quicklime, quicklime is a natural disinfectant, cheap, easy to buy, use and distribution, so it is often used as disinfection. However, if it is not used properly, it will not only not pay attention to disinfection and sterilization, but also a waste of manpower and material resources, and in serious cases, it will lead to symptoms such as burns of pigs. So how to disinfect with lime? What are the points for attention? Let's get to know it.

1. Misunderstanding of lime disinfection

When many pigs are disinfected with lime, they just clean the pigsty and sprinkle some lime powder on every corner. In fact, this is wrong. This not only fails to play the important role of disinfection and sterilization, but also causes pigs to eat lime powder by mistake, causing burns to the oral cavity and digestive tract, or during the activity, the lime powder is lifted, causing pigs to inhale lime powder, which can easily lead to respiratory diseases. Some people spray lime powder with water in the pigsty, which is also wrong, so that the solution can not be used until the solution cools, but the solution will react with carbon dioxide in the air, reduce the content of calcium hydroxide, and the effect of disinfection and sterilization is low. In addition, lime should not be stored for too long, otherwise it will react with carbon dioxide to form calcium carbonate and lose its original disinfection and sterilization efficacy.

2. The correct method

Quicklime itself does not have disinfection around, only when it is mixed with water to form hydrated lime, which has strong alkalinity and high disinfection and sterilization effect, so direct application of lime powder during disinfection does not have any disinfection effect. The correct method should be to spray an appropriate amount of water on the floor of the pig house, and then sprinkle the lime powder on it to form calcium hydroxide after the reaction, which plays the role of disinfection and sterilization. It can also be made into 20% lime milk with water and smeared on the wall or floor, so that it can not leave a dead corner, but also play an important role in decoration, and should be used in a short time after it is made, so as not to lose its effect.

3. Points for attention

When in use, we should pay attention to whether the lime contains impurities, otherwise explosion and combustion may occur in the process of mixing water; quicklime has the effect of disinfection and sterilization only after a chemical reaction occurs after meeting water, and it does not have any disinfection effect to use it directly; lime milk must be used now, and the disinfection and sterilization effect may be lost for a long time; before disinfection, the last cleaning work must be done at the disinfection site.
