With the gradual increase of temperature, the environment of livestock and poultry breeding deteriorates more rapidly with the increase of temperature. This requires breeding workers to disinfect the breeding environment before the environment deteriorates. However, disinfection is not a random operation. Many breeding workers are prone to certain misunderstandings on the issue of disinfection. These misunderstandings are:
1. No disinfection is required if no epidemic has occurred.
The main purpose of disinfection is to kill the pathogen of the infectious source. There are three basic links for the occurrence of the disease: the source of infection, the route of transmission, and the susceptible animals. In livestock and poultry breeding , sometimes no epidemic occurs, but there are sources of infection in the external environment. The source of infection will release pathogens, which will invade susceptible livestock and poultry through air, feed, drinking water, etc., causing disease. If the environment is not disinfected and purified in time, the pathogens in the environment will accumulate more and more, and when it reaches a certain level, the epidemic will occur. Therefore, farmers in areas where no disease has occurred should be disinfected to prevent them before they occur.
2. Before disinfection, the environment is not completely removed.
Due to the large amount of organic matter on the farm, such as feces, feed residues, livestock and poultry secretions, body surface shedding, and rat dung, sewage or other dirt, these organisms conceal a large number of pathogenic microorganisms, which will consume or neutralize and disinfect The effective ingredients of the agent have seriously reduced the concentration of the action on pathogenic microorganisms, so that thorough removal is a prerequisite for effective disinfection. Generally, it should be cleaned (in order to prevent dust from flying, it can be sprayed with disinfection water beforehand), rinsed (including the washing of poultry houses, equipment and feeding equipment), and then disinfected.
3. Infectious diseases will not occur after livestock and poultry have been disinfected.
Although disinfection is carried out, it is not always possible to obtain a thorough disinfection effect, which is related to the type of disinfectant selected, the quality of the disinfectant and the disinfection method. Even after disinfection has been fully regulated, it is safe in a short time, but many pathogens can be transmitted through the air, birds, rats and other media. Farm animals continually pollute the environment and also cause a large number of pathogenic microorganisms in the environment to multiply, so it must be Regular, positioning, thorough and standardized disinfection, combined with planned immunization, can ensure that farmed animals must not get sick or have fewer diseases.
4. The stronger the disinfectant smell, the better the disinfection effect.
The disinfection effect is mainly related to its sterilization ability and spectrum. At present, some advanced and good disinfectants in the world have no odor, such as persulfate. On the contrary, some disinfectants with strong odor and strong irritation have a dead zone of disinfection, and have strong odor and strong irritant. It has certain damage to the respiratory tract and body surface of livestock and poultry, but it is easy to cause respiratory diseases.
5. Long-term fixed use of a single disinfectant.
If a single disinfectant is used for a long period of time, bacteria and viruses may also develop resistance to it. At the same time, because of the broad sterilization spectrum, it may not be able to kill a pathogenic bacteria and cause it to multiply, and it may also have resistance to disinfectants. Therefore, several different types of disinfectants are generally used in rotation.
