Pig farming is a complicated process. Throughout the pig production process, pig farms have a high density of pig farms. High-density pig farms may have diseases at any time, and the diseases that grow in pigs are easily contagious. Group outbreaks, the rate of expansion is extremely fast. If the spread of the disease is not curbed in time, the losses will be very severe when the scale of the disease is larger. Therefore, it is very important to do a good job of herd health detection during the pig raising process, to detect the disease in time, to control the epidemic early, and to eliminate the infectious diseases in the bud state.
So, how to monitor the health of herds in the pig farm during the pig raising process? This is a problem that pig farmers are very concerned about.
1. Observe the usual living conditions of the herd:
Pig breeders need to observe their pigs at any time. If abnormal living conditions are found, they should report to the veterinary staff or technicians in time. Farm technicians and medical staff should visit the herd at least 2-3 times a day during the critical period of piglet growth, and often contact the breeder to exchange information to grasp the growth dynamics of the herd. Be careful and meticulous when observing herds, and master the observation techniques, timing and methods.
Generally, in the process of pig production, "three looks" can be used to judge, that is, to look at the spirit, feed to appetite, and clean up the feces. The pig's age, sex, physiological stage, season, temperature, air, etc. should be considered, and observation and recording should be carried out in a focused and purposeful manner. If any abnormal situation is found, it should be analyzed in time to find out the cause and take measures to solve it as soon as possible. If it is a general disease, it should be treated symptomatically or eliminated. If it is a severe infectious disease, it should be immediately killed and properly treated, and emergency disinfection and immunization measures should be taken to prevent its spread and spread. Eliminating abnormal pigs in time will not only reduce the consumption of materials and medication, but also help maintain the safety of the entire farm.
2. Measure the growth status of specific pigs:
For specific breeds or crossbreeds in pigs, it is required to breed at a high-end specified breeding management level, and at the same time to show a specific production level. By measuring statistics, you can know whether the level of feeding management is appropriate and whether the health of the herd is in a good state. Poor feeding management can not achieve the maximum genetic potential of pigs, while also reducing pig health.
3. Anatomy and inspection of sick pigs:
The dissection and examination of sick and dead pigs is very important in the clinic. Professionals can understand the types of pig diseases and the types of disease by observing the disease or the type and degree of the disease in each organ and tissue through the dissection and examination of the sick pig And severity.
4. Antigen and antibody monitoring:
Pig farm professionals should regularly check and determine antibody levels in serum and body fluids, which is an effective way to understand the immune status of animals. The presence of an antibody in the animal's serum indicates that the animal has been in contact with the homologous antigen. The presence of the antibody means that the animal is sick or has suffered from the disease in the past, or that the animal has been vaccinated. If antibody levels are down, these antibodies may be remnants of an infectious disease or vaccination. Testing the antibodies after vaccination can clarify the effectiveness of artificial immunization and serve as a reference for when to vaccinate in the future.
After vaccination of pregnant sows, piglets can obtain maternal antibodies by eating colostrum. Determining the amount of maternal antibodies in piglets can understand the immune status of piglets, and is also an important basis for determining when piglets are vaccinated. The technology used to check antibodies can also check and identify antigens and diagnose diseases. At the production site, simpler methods such as whole blood agglutination tests can be used to quarantine certain diseases, eliminate positive pigs, and purify the herd.
In the process of pig breeding, we must 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 herd disease. A two-pronged approach ensures the safe and rapid growth of pigs.
