The low temperature and humid environment in winter is conducive to the proliferation of many pathogenic microorganisms, which may easily lead to the occurrence of diseases. Therefore, it is also an important part of the environmental control of winter pig houses to eliminate disinfection measures, eliminate pathogenic microorganisms in the external environment, and eliminate the transmission route of epidemics. 1, pig house disinfection: winter pig house environment is closed, dust, harmful gases and other pollutants suspended in the air, suitable for the growth of pathogenic microorganisms, easily lead to the occurrence of disease. Therefore, it is necessary to strengthen the regular disinfection of the pig house and timely eliminate the pathogenic micro-bacteria in the pig house. Before the disinfection, the manure and urine in the pig house should be cleaned first, and the disinfectant without irritating odor such as potassium persulfate complex, chlorine dioxide or chlorpyrifos can be selected. 2, environmental disinfection and approach control: the purpose is to ensure the size of the field, the main road and the bio-safety after the circle. High-pressure spray disinfection can be carried out using 0.2%--0.3% peracetic acid or 2% caustic soda. In general, the disinfection frequency is set at 2 times/month. In order to ensure the biosecurity of the audience, we must also pay attention to the control of the approach. It is necessary to minimize the entry of off-site personnel into the production area, and the entry and exit of articles and personnel must be disinfected. In smaller farms, veterinary drugs, feed salesmen, pig dealers, etc. should be prevented from entering the pig house directly. 3, disinfection tank disinfection: the use of 2%-3% of the various disinfection tanks in the field, every 1 to 4 days to replace, should pay attention to keep the disinfectant in the pool at a reasonable level. In addition, in order to prevent the hoof disease of the breeding herd, the pool can also be used with 1:80 disinfection, or they can be used interchangeably. medical protective suit with shoecover,medical protective suit without shoes cover,hazmat suit,hooded coverall without seal tape Shandong Zhushi Pharmaceutical Group Co.,LTD , https://www.sdzs-medical.com
