1. Quarantine before entering the slaughterhouse

Quarantine before pig slaughtering is very necessary, before the pigs enter the slaughterhouse, it is necessary to master the quarantine process and standardize the implementation in the actual work. After the pigs are transported to the slaughtering place, the relevant certificates of the pigs should be strictly inspected, including origin quarantine, transportation quarantine, etc., and then the source of the pigs should be inspected to ensure the standardization and effectiveness of the inspection. After determining the source of live pigs, review their specific immunization period and ascertain their health status. The behavior of live pigs entering the slaughtering site is carefully examined, including dynamic behavior and static behavior. Under the special conditions of epidemic swine diseases, pigs to be admitted to the slaughterhouse are required to hold a certificate of non-infected area, which is a necessary way to effectively prevent swine epidemics. In the quarantine process before entering the slaughterhouse, it is necessary to accurately check the number of live pigs, and carry out inventory at the first time when abnormalities are found, in order to understand the specific situation of pig transportation, and to grasp the health status of existing pigs through a comprehensive inspection, so as to ensure the effectiveness of the pre-slaughter quarantine.

2. Inspection before slaughter

Before slaughtering pigs, the standardization and effectiveness of pig inspection should be ensured through individual inspection and sample inspection. Before slaughtering, new pigs should be isolated for observation and comprehensive inspection, and should not enter the slaughtering process blindly. In the process of individual inspection of live pigs, physical examination is carried out by touching, seeing, hearing and other diagnostic methods to grasp the health status of live pigs, and isolation inspection is carried out if necessary to confirm that the inspection is qualified before they are allowed to enter the pig pens in the slaughterhouse. Before the slaughter of pigs, we need to implement sample inspection with the qualified pigs as the object of physical examination, grasp the time interval of inspection, carry out regular inspections, closely observe the dynamics of pigs, including diet, exercise, etc., once the abnormal conditions of pigs must be isolated in a timely manner, and visual mucosa, oral mucosa, feces, etc. as the object of inspection, and carry out a comprehensive and detailed inspection of the isolated pigs.

3.Re-inspection before slaughter

Do a good job of re-inspection before pig slaughter, mainly through the re-inspection to determine the health status of the herd, which is an important part of the process of pig slaughter and quarantine, in order to ensure the effectiveness of the re-inspection of pigs before slaughter, need to be combined with the specific conditions of pigs, on the basis of a comprehensive inspection of the individual implementation of the individual pig focused on the inspection, to ensure that the pigs are qualified for the quarantine of the pigs before slaughter, and to promote the pigs to enter the slaughter stage smoothly. Re-inspection of pigs before slaughter is mainly relative to the body temperature of pigs, through the body temperature check again, it is easy to grasp the specific situation of pigs before slaughter, and then take effective measures. Due to the transportation link will affect the physiological state of pigs to a certain extent, when the pigs appear stress reaction, need to be combined with the specific symptoms of pigs to carry out a comprehensive analysis of the emergency slaughter of pigs to deal with the implementation of a comprehensive quarantine, and based on the quarantine of pigs after the slaughter of pigs stamped with the appropriate seal, so as to prove that the health of the pigs, and harmless treatment if necessary, to avoid the growth or spread of bacteria.

The re-inspection of pigs before slaughter is a kind of specialization work, which is mainly reflected in the group quarantine and individual quarantine, the group quarantine takes the pigs as the object, and determines the health condition of pigs by observing the specific dynamics of the pigs, and the common indexes include diet, drinking water, vomiting, squealing, etc. The observation of the activity of the pigs is realized by the way of expulsion to observe whether there is the problem of dropping the single in the pigs and the abnormality of the excretion, etc., which can ensure the effectiveness of the group quarantine before slaughter of the pigs. The effectiveness and reliability of group quarantine before slaughter. When individual quarantine is implemented before pig slaughtering, it is mainly to check the individual pig through various diagnostic methods, taking fur, appearance, secretion, excretion, heartbeat, body surface and so on as the main points of quarantine. If there is purulent secretion, diarrhea, or blood in feces, it can be judged that the individual pig is infected with a certain disease. If there is abnormal heartbeat, abnormal gastrointestinal peristalsis, nodules in lymph nodes, swollen skin, pain in chest, etc., it can be concluded that the individual pigs are infected with certain diseases. Before the slaughter of live pigs, through the group quarantine and individual quarantine to carry out a comprehensive re-inspection, easy to accurately grasp the health status of live pigs, to ensure the standardization of the slaughter and quarantine of live pigs, and to create favorable conditions for the safety of live pigs and meat products.
