(1) Health monitoring
Health monitoring is to find all kinds of hidden dangers and individuals carrying pathogens through a comprehensive inspection of healthy groups, and then adjust the feeding management system and immune preventive measures of the whole herd in a targeted manner. At present, the focus of health monitoring in pig farms is mainly to solve the infection and epidemic problems of some reproductive disorders, respiratory syndrome, multifactorial diseases and recessive infectious diseases. Health monitoring can be carried out by daily inspection of pig growth and development and detection of collective antibody level. , so as to fully grasp the production situation of pigs, find problems in time, adjust the nutritional level of diet, improve environmental and climatic conditions, strengthen daily feeding management, keep pigs in a good physiological state and reduce any risk of illness.
On the basis of health examination, it is necessary to carry out group health care for pigs, which can not only improve the production performance of pigs quickly, but also make pigs grow and develop healthily. The focus of group health care is on pigs during pregnancy, lactation, seed conservation and high yield.
(2) Epidemiological surveillance
Regularly checking the health status of pigs, collecting and analyzing the data of common diseases and daily production conditions of pigs, monitoring the dynamics of various diseases and the effect of epidemic prevention measures, comprehensively evaluating the healthy development of pigs and predicting the risk of diseases are the main tasks of epidemic monitoring and an important part of the epidemic prevention system of pig farms. Through routine epidemic monitoring (quarantine) means such as daily patrol inspection and serological detection, we can master the health status of pigs, the occurrence of diseases in the field, the immune quality and the level of epidemic purification, and also provide objective basis for epidemic prevention work in this field. Especially the outbreak and epidemic of major infectious diseases in this region and this season, we should strengthen prevention in order to respond in time. At the same time, the quality of vaccines and disinfectants used in the field should also be tested to ensure that they are really effective. If we can't do the above work in time, we can't accurately and deeply understand the epidemic and development trend of pig farm diseases, let alone take effective prevention and control measures in time, thus affecting the healthy growth and development of pigs.
