In the traditional concept of people, disinfection will cause a large number of functional bacterial flora to die, leaving the fermentation bed to lose the effect of fermentation and decomposition, which is the so-called "dead bed", so the fermentation bed housing cannot be disinfected. In actual fact, after a lot of experiments have proved that as long as the operation is properly, the fermentation bed can be completely normal disinfection. Studies have shown that the use of compound iodine solution, compound phenol solution, compound glutaraldehyde, and sodium dichloroisocyanurate powder commonly used in pig farms have no adverse effects on the total number and temperature of live bacteria in the fermentation mattress material. After general disinfection, the number of strains can be restored by 70% within 48 hours and reach the pre-sterilization level within 3-5 days. Ordinary disinfection has almost no effect on the amount of bacteria in litter below 30cm. With the extension of the time after disinfection, the effect of disinfectant is reduced. The bacteria began to recover.
1. The method of disinfecting the dry-sweeping fermentation bed: (1) Spray disinfection. This method is suitable for the surface disinfection of the fermentation bed, is to deal with general epidemic prevention and epidemic prevention and simple disease disinfection, the use of a medium dose, you can achieve the purpose of disinfection (after disinfection, generally do not turn the bed surface 3-5 days). In addition, the litter has strong adsorptivity, and the disinfectant should not be diffused and infiltrated and will be quickly degraded, which greatly reduces the impact of disinfecting on animals. (2) Fumigation: It is a kind of disinfection method that is usually adopted when the animal is first entered or when the bed is vacated. It is mainly to achieve complete disinfection of the housing. Mostly used for the disinfection of chickens, ducks, geese and other pens, the disinfection of piggery is less in this way. (3) litter accumulation sterilization. This is a unique disinfection method of the fermentation bed, and it is also the most common and most commonly used method of disinfection. It mainly consists of stacking and fermenting the litter during the empty period. The fermentation produces a high temperature of 40-60° C. and uses the long-lasting high temperature to kill harmful germs and eggs in the litter, thereby achieving a complete disinfection effect. Studies have shown that when the fermentation temperature is maintained at 55°C for more than 3 days, or at 50°C for 5-7 days, pathogenic bacteria in the litter can be killed, and important conditions for qualified hygienic indicators can be achieved. (4) Other disinfection. According to the actual situation, you can also choose other disinfection methods. Such as: fixed local disinfection, layer disinfection and so on.
2. The precautions for disinfecting the dry-type fermentation bed: (1) No toxicity. The fermentation bed is not necessarily disinfected for most of the time because in the fermented mattress material, the active and powerful functional flora predominates and there is almost no living space for pathogenic microorganisms. In other words, the dry spreader has its own disinfection. (2) timely disinfection. Disinfection should be based on the actual situation, choose the right time. Disinfection should be strengthened when there is an outbreak threatened around, but there is no need to disinfect most of the time without the threat of an outbreak. (3) Focus on disinfection: The focus of fermentation bed disinfection is not on the fermentation bed itself, but on the links with the outside world, such as people, vehicles, materials and gates.
Throughout the development history of the fermentation bed, the problem of disinfection of the fermentation bed has certainly been a cliché problem. It will continue to be asked and answered in the past and in the future. However, it is certainly not enough to rely solely on chemical agents to control the disinfection of disease spread on the fermentation bed. In the future, there will be more scientific and reasonable disinfection methods waiting for us to study and develop.
