First, observe diligently.
Pigs should not be lazy. Pig farms should arrange professionals, such as technicians or veterinarians, to inspect pigs at least 2-3 times a day, and often communicate and exchange information with breeders in order to grasp the dynamics of pigs in real time. If abnormal reactions are found, countermeasures can be taken in time.
We should be careful when observing the state of pigs. We should judge the health status of pigs according to their mental state, appetite, feces, age, sex, physiological stage, season, temperature and humidity, air quality and so on. If any abnormality is found, it should be analyzed in time to find out the reason and take measures to solve it as soon as possible.
General diseases should be treated as soon as possible, and severe infectious diseases should be isolated immediately, treated harmlessly when necessary, and emergency disinfection and immunization measures should be taken to prevent their spread.
Second, the production level is measured and counted.
The productivity level of pigs is a barometer reflecting the quality of feeding management and health status. For example, the low conception rate and litter size of pigs are often related to poor feeding technology, improper feeding management and some diseases; Low birth weight is related to sow malnutrition during pregnancy; 2 1 day-old piglets have small litter weight and poor uniformity, which are related to insufficient breast milk, late or improper feeding, bad environment or disease onset; The low daily gain and poor feed reward of pigs may be due to some chronic diseases hidden in pigs or improper feeding management. Based on these factors, accurate measurement and statistics are needed to know whether the feeding management level is appropriate and whether the health of pigs is in the best state. Poor feeding and management can not give full play to the maximum genetic potential of pigs, but also reduce the health level of pigs.
Third, the autopsy of sick pigs.
It is very important to dissect the dead pigs in clinic. By dissecting sick pigs, we can observe whether there are lesions in various organs and tissues or the types and degrees of lesions, so as to understand the types and severity of diseases in pigs.
Four, antigen and antibody monitoring
The monitoring of antigens and antibodies, first, can make clear the effective degree of artificial immunization and provide reference for when to vaccinate again in the future; Second, it can help to infer whether you have some kind of disease. Because antibodies in serum can indicate that pigs have been in contact with homologous antigens, or that pigs are sick or have been sick in the past, or that the vaccination of pigs is effective. If the antibody level drops, it means that these antibodies may be infectious diseases or residual antibodies after vaccination.
After pregnant sows are vaccinated, piglets can obtain maternal antibodies by eating colostrum. Determination of maternal antibody of piglets can not only understand the immune status of piglets, but also be an important basis for determining when piglets will be vaccinated again. Some diseases can be quarantined by simple methods such as whole blood agglutination test in production site.
In the process of pig breeding, we should not only pay attention to the environmental monitoring of pig breeding, but also pay attention to the growth status of pigs to avoid the occurrence of pig diseases and ensure the safe and rapid growth of pigs.
