pig breeding in order to achieve the established goals for each batch, environmental adaptation gilts around the past is a part of. Before breeding, the introduced reserve pigs need to be exposed to the pathogenic microbial environment in the original pig group, so that the reserve pigs improve the immunity, not affected by sudden illness. Another purpose of environmental adaption management is to ensure a stable reserve pig to the breeding workshop to meet the needs of breeding objectives. In order to achieve these two purposes, there must be a set of detailed management procedures. The scale pig farm only has the correct implementation of the environmental adaptation procedure, so that the rear presence pigment is gradually exposed to the microbial environment of the original pig group to ensure that the breeding has high immune power to introduce the breeding target.

The environmental adaption period means this time from the reserve sow to introduce the pig farm to the breeding. Everything done during this period is to make the introduced reserve sow can have a longer reproductive life. The main purpose of management is to ensure that sufficient reserve pigs are provided to the partner to achieve breeding objectives. If the rear preparation pig is threatened by high-level pathogenic microorganisms (bacteria and virus) during this period, they cannot estrurist or delay, so they cannot meet the number of different sows required for breeding. Therefore, the adaptation procedure is designed to contact the original pigs in contact with the original pigs, which is gradually exposed to the original pig group, which can cause the rear preparation pig to generate immunity to the existing disease of the pig farm, for those previousDated diseases can also produce immunity without causing the rear presence of pigs infected with the disease. In addition, the reserve pigs also take time to adapt to new environments, new feed, new water supply systems and breeders after long-distance transportation. Another important part of the environmental adaption period is to expose the researchers to the boar, thus stimulating estrus. Appropriate stimulation procedures can estrus the resembled mother pigs in a suitable time in order to breed by the time required.
Due to the case of various pig farms, the right environmental adaptation procedure is required to be formulated by the pig farm veterinarian. The formulation procedure must consider the difference in the introduction of the health of the species and the pig farm, some special diseases and facilities that can be provided. Typically, before, in front of a series of procedures to implement an environment, it is necessary to isolate a period of time.
Environmental Adaptation Program: This “program” is different from the program that lists management content in an environmental adaptation period of up to 12 weeks, which can be used to discuss specific procedures for each farm. Including the rear presence of mother pig environment adaptation scheme, vaccination scheme, and an overall epidemic prevention plan.
The following is a few concepts of isolation and environmental adaptation:
The isolation must be emptied before the pig, then flush and disinfect. Once you enter the pig, strict measures must be implemented to prevent the incoming disease with the pigs. The breeder enters and exits the shower, wearing special clothing and boots. Regular work such as: feeding, check, etc. should be done in the final, and can no longer return to the original pig.
During the discharge period, the resell of the mother, must be checked daily, see if there is no clinical symptom, any abnormal situation should be recorded, and inform the veterinarian in time. It is important to introduce the pig farm and the veterinarian of the pig farm. It is important to introduce a variety of pigs, and should immediately tell the veterinarian in the investment of the pig farm.
veryMulti-disease has a 3 weeks of latency, so the veterinarian must conduct a health check against the reserve pig before mixing the rear preparation pig before the original pig group, that is, the fourth week of isolation. This includes examining and introducing a veterinarian invested in a seed pig farm, introducing a pig farm having no new disease, and is clinically healthy. It also includes immunity to test certain diseases. Once all inspections indicate that the pig is only very clean, the reserve pig can go to the environment to adapt to the pig house. The isolated process consumes more expensive, but it is the most basic way to protect the health of the original pigs, and make the rear sow have time recovery after transportation.
Transfer Environment Adaption: The backup sow after isolation should be long to 95-100kg. If the rear stock is directly entered into the environment, we should have 100kg, about 150 days. In either case, before entering the mother pig, the environment should be emptied, flush, and disinfect. It is definitely not to raise the researcher with other pigs, and it is best to stay away from other pig houses as much as possible, preferably in the edge of the pig farm. Sometimes, the environmental adaptation procedure is also in the isolation house.
Environmental Adaptation Period: In order to have a seminated mother pig in the pathogenic microorganism of the field, it gradually established immunity and at least 4-5 weeks. However, the reserve sow is in the third estrus, so it is assumed that they have entered the environment for 7 days after 7 days, then the third estrus is 1 week, that is, they can go 6 weeks. Face room. In practice, this period is usually 6-7 weeks, depending on the time of the first estrus of the reserve sow. If the pig farm invested into a pig is threatened by the disease, the veterinarian will recommend extending the environmental adaption period, so the weight of the stored sows should be smaller, so that the pig farm will produce better breeding results.
Immunization: Immunization is a very important way to cause immunity to produce immunity against farm, which is much more reliable than exposure to pigs, and more effective. The immunization procedures of the reserve sow are annotated in the immunization plan, usually starting from the initial production of 3 weeks from the initial production of 1 week. The correct vaccination time, dosage, and injection technique are critical, otherwise it will reduce the protection or expire all immunization.
Exposure to the pathogenic microorganisms of pigs: Under normal circumstances, it takes 7 days after the re-binding pigs reaches it to recover from transportation and adapt to the new environment, because the immune function should be temporarily lowered. Be started from the second weekIn the pathogenic microorganisms exposed to the pig, this method is not the most appropriate scientific method, because the disease level in the pig group is unstable, so the immune extent obtained in the process of contact with the pig group is also different. However, the principle is to make the number of reserved pigs contact pigs and feces, which can make the immune levels tend to be consistent, without revealing the immune system of the rear sow. The type, quantity and inoculation time of pigs are determined according to the opinions of the veterinarian. Put some young elimination sows (produced the first child and the second child) within the column of adjacent rearing sows, according to the proposal in the procedure, the pig is allowed to have nasal contacts. These eliminated mother pigs are more likely to spread the pathogens than old sows, as old sows have high levels of immunity. The feces of pigs and piglets is also a better source of pathogens, and a small amount of feces can be taken for a long time. This low level of exposure should last for 2-3 weeks, in order to cause adequate immunity before entering the house.
Stimulating Emotion: Contact with the boar will affect the first estrus of the rear sow and the synchronization of the same pig. Typically, the backbone of the mother pigs into the environment within 5-7 days, and the few sows in the entire group will begin the first estrus. The purpose of stimulation is mainly in order to make all the re-prepared sows in as short as possible. From the third day of the environment, you will have a ripe boar to stimulate estrus, twice a day until all the rearing sows have emerged, and the time of the reserve sow card is logged. In the second day of the second estrus, I used the boar to stimulate until all the sows were estrus and recorded. This second stimulus is to improve the synchronization of the entire pig, but also to predict the time of the third estrus (ie, the breeding).

From the third day of the environmental adapted period, the ripe boar is stimulated, two times a day, until all the rearing sows have emerged, and the time in the rear softer card. In the second day of the second estrus, I used the boar to stimulate until all the sows were estrus and recorded.
