With the continuous increase in the scale of pig production, the epidemic has become more complex. In order to effectively control the disease and improve economic efficiency, it is necessary to carry out reasonable health tests and active and effective health care measures for the pigs.
Create a good pig house environment. A good pig house environment and proper feeding and management can not only improve the pig's production performance, but also it is a proactive measure to improve the health of the herd, increase herd resistance, and reduce herd stress. Peacetime should be kept clean and comfortable, good ventilation, winter insulation and cold, cool summer heatstroke. Reasonably formulate and strictly implement the feeding and management points of the pigs at each stage to improve the overall health of the herd.
Adhere to self-cultivation. The pig farms are frequently introduced into different regions, and it is easy to introduce various pathogens into the field. At the same time, due to the different susceptibility of newly introduced pigs and original pigs to different pathogens, epidemic diseases can easily occur. Therefore, pig farms should insist on self-cultivation and self-cultivation, with as little or no introduction as possible. If introduction is required, pig farms with healthy disease-free should be selected. After introduction, they should be isolated for observation for 2-3 months. The original pig herd.
Isolated breeding, all in and out. Isolated breeding, also known as multiple isolation production, is to keep pigs in different stages of the life cycle in different places. When more pigs are raised, the production process is divided into breeding, pregnancy and delivery, conservation and fattening. These pigs at different stages can be kept in 3 separate places. A two-point system can also be used, ie breeding, pregnancy and delivery in one place, nursery pigs and finishing pigs in one place. All-in, all-out, that is, the same batch of pigs in the same period into a pig house (field), the same period out of a pig house (field), all the pigs transferred out, after a thorough cleaning and disinfection after a week and then enter the next batch of pigs. This can eliminate the pathogens left by the pigs in the previous batch and provide a clean environment for new pigs to further avoid circulating infections and cross-infections.
Sanitary disinfection. Disinfection is the use of disinfecting drugs to kill or eliminate the pathogenic microorganisms that are released from the source of infection to the external environment. Its purpose is to cut off the route of transmission and prevent the spread and spread of animal infectious diseases. Enhancing the disinfection of feed, drinking water, ground, feed troughs, feeding tools, and vehicles in and out is of great significance in preventing infectious diseases. Disinfectants should be selected to be non-toxic or low-toxic and highly effective, and use drugs alternately to avoid drug resistance.
Immunization. Immunization is an important means to stimulate the pig's body to produce specific resistance and reduce the susceptibility of swine. It is one of the important measures to prevent and control the occurrence of swine infectious diseases. Farms should be immunized in strict accordance with scientific immunization procedures, timely and accurately monitor immune antibodies, and develop appropriate immunization procedures based on the monitoring results to ensure that the herd is always in an immunoprotective state. The focus should be on the prevention of viral diseases such as swine fever, blue ear disease, and foot-and-mouth disease.
Drug care. Mainly refers to the use of drugs for the control of bacterial diseases, viral diseases, parasitic diseases, but the scale of the pig farm is generally from the two aspects of bacterial diseases, parasites, and for viral diseases through drug care is The effect is poor and the cost is too high. Therefore, it is better to control the viral disease through vaccination. The pig farm must first investigate the epidemic characteristics and patterns of bacterial diseases and parasites in the field, and reasonably perform drug care.
