Determines the management process of the rear sow is one of the core key points. At this stage, the design of the reserve mother pig house is insufficient. This article will make a brief introduction to the design and management of the backparent pig house, I hope to help readers.
1, Isolation Domestication
The design and management of the bonded pig hosteau is the largest effect of the sow house. The resembled mother pigs enter the group, which may be introduced into new diseases, or infect the original disease in the field after entering the group. In order to keep the swine group healthy and stable, it is generally isolated and domesticated before the resell of mother pigs. Regarding the researchers of the mother pig isolation, the author makes the following brief introduction.
In order to prevent the post-prepared sow from being introduced into new epidemic, such as Blue Ear Disease PRRS, Pseudo Track Pr, Pathogenic Diarrhea PED, Pork Fever HC, requires isolation of the rear sow. Among them, the anti-veneer PR, swine fever HC, etc. can be detected by laboratory during isolation, and vaccinated in time is performed in time. For diseases such as blue ear disease PRRS, epidemic diarrhea PED, with strong infectious, harmful, and limited market vaccine protection effect, need to take isolation measures to reserve sows, let them use autoimmune systems to remove vivo pathogen Thus reducing the risk of torgets.
In order to prevent the pathogens in the infection of the mother pig farm after the post-bonding pigs, it is necessary to domestication of the rear sow during the isolation to reduce the risk of infection. For diseases such as swine fever, pseudoal travelers, foot-and-mouth disease, dieb, fine, ring, pig Danzi, etc., generally adopt an immunization control method. For some vaccine prevention and control effect, it is harmful to large epidemic (such as blue ear disease, epidemic diarrhea, etc.), which allows the rear stock to contain a wild-containing material (feces, dead fetus, elimination of sows) , Abortion sows, small intestines, serum, etc.) to establish certain immunity.
In many European and American pigs, the pig has high health, and the reserve mother pig isolation and domestication plan is more mature. It can be used for reference, but the domestic pig farm has a different situation, many pig farm organisms Safety conditions and production management levels are poor, and they have not purified pseudo-ram, swine fever, etc., need to be cautiousMerly is domesticated, avoiding the new fierce infectious diseases infected with backfish. Given the status quo of complex pigs in China, it is recommended to adopt a strategy of “isolation main, cautious domestication”.
Theoretically, the higher the health level of the introduction, the lower the risk of incoming epidemic disease. For blue-ear disease positive stable pig farms, if the reserve sow of 3-5 weeks old, it can be obtained from the prime pig (PCR detection). In the previous period of preservation, the pig group is easily infected with blue ear disease virus due to loss of maternal antibody protection, and serological detection of blue ear disease antibody has increased. Therefore, in a pig group having a weight greater than 50 kg, the difficulty of retaining the daughter after the negative sow is large, especially in a point-produced pig farm. Pig ring virus diseases and pseudo-rabies have similar situations. For the reserve sows in the same field, theoretical small day-old pigs are “clean” than the big age, the latter infection is high, and it is recommended to choose a small age of small age. There is sufficient time to isolate domestication.
About the reserve mother sow, the development of the corresponding scheme is first developed according to the actual problems existing in this field, and the specificity of domestication and corresponding evaluation criteria should be made. In principle, it is possible to use vaccine immune to prevent and control, do not use other materials to be domesticated; can be domesticated with natural infection, do not use muscle injection and other ways. Domestication is not universal, just a supplement to existing immune prevention and control systems. At present, there are often domestic pig farms, and there is a dazzling project with blue ear disease, Escherichia coli (white diarrhea), viral diarrhea (PEDV). Compared with other diseases, pigs are long and tetanous and tetanous are long and harmful, and is generally the main reference objective for the isolation of resembled mother pigs.
About the reserve mother sow blue ear disease, its key point is that biological safety is strict, the isolation time is long, usually 3-5 months. The first month is observing the quarantine period, and during this period, the health status of pigs is observed, and the blood collection test evaluation is performed. Domestication can be carried out if necessary. For blue-ear disease bungeic pigs, if wild toxia is used, the general body is 3 weeks after the antibody will be turned into a yang; 2-3 months no longer tap, the antibody begins to decline; 3-4 months post, the body is no longer brought Toxicity; after 4-5 months, the antibody becomes negative. If you use blue ear disease, the body antibody has a small change in body antibody and a short detoxification time compared to wild toxia. Generally, the backpass of the mother sow is a sow.General S / P value
The author critored 952 pig farms in the past three years, 3% of the pig farms were blue ear disease negative fields These fields are mainly concentrated in the core groups of pig enterprises and the trace households in remote areas. For larger pig farms, single field can be purified by blue ear disease, but it is necessary to maintain a negative is difficult to maintain a complete biosafety system for a long time. Among them, scientific location, multi-point layout, closed group feeding, batch production, empty house disinfection, vehicle disinfection, and resellual pig isolation and domestication have become the basic means of prevention and control of diseases in scale. Individual pig farms have even installed air filters to reduce air level propagation.

For the blue ear disease negative mother pig farm, the resembled mother pigs do not need to be dazzling to be domesticated, and should focus on isolation. It is recommended to take advantage of the post-prepared sows from the wear pigs in this field, and leave it directly in the cultivation house in the sow field, no longer transfer from the sow. The advantage of this strategy is more easily controlled for the health of the reserve sow, which is conducive to the stability of the sows, and the drawback is due to the smaller pigs, which requires a large returning strength to meet the breeding needs, or In the case of incubation or fattening houses, 20-60 kg of weight of the blue ear disease (antigen and antibody) reserve a sow (antigen and antibody), and transferred it to the rear-home sow culture () for 1-3 months. Due to the uncontrollable factors outside the system, the income risk of the disease is large, try not to introduce the outside of the system, if it is indeed introduced, it is recommended to introduce the health level higher than the existing sow in the existing sow, the best It is separated by isolation for 2-4 months in a rear-backed breeding site, and the pig house takes a small unit design. Each batch of pigs will carry out all the full out of the field (), avoiding the backup of the system. The sow is placed at the same time in a field, and the test results can be obtained after passing the results. Avoid introducing the blue-ear disease positive sows (the most risk) from the outside of the system, if the positive backparent sow is introduced, it is necessary to put it in the reserve mother pig breeding field.Leaving 3-5 months until the blue ear disease test results are dual negative, they can take into account the group. Only stringent biosafety measures are taken to eliminate various vulnerabilities, and the sows may maintain a negative state in a long time for a long time.
1.2 Blue-ear disease positive stable field domestication
Due to the vast majority of pig farms as blue ear disease positive fields, general pig farm health management goals are stable to keep pigs, and continue to supplement health. High reserve sows, gradually purifying pork fever, pseudohaves, etc. in the field, constantly improving the health level of pigs.
Generally, 50-60 kg of weight, pseudo-raw sow, the pseudo-raw sow, the pseudo-raw sow, the pseudo-morale, and most of this stage have naturally infected the blue-ear virus in the field, no need to carry out blue The ancient domestication project is placed in the reserve sow, and is isolated for 1-3 months. It is also possible to choose a reserve pig in the system or introduce a double-negative sow from the system to the system, and transfer it to the reserve sow cultivation (field) to isolate the breeding, generally 3-4 months before breeding. Domestication. If you choose to introduce 40-60 kg of blue-ear disease positive sows from the system, the risk of introducing the blue ear sterilized drug plant is large, generally need to separate it separately in the reserve sow culture field to isolate domestication 3-4 months.

About blue ear disease domestication methods, it can be vaccinated with blue ear diseaseVaccine, or after contacting the rear bonding pigs in a manner that contains the venue of the blue ear disease (dead, abortion sow, elimination of sows, serum, etc.). Each batch is better in the field () in units to reduce the virus level propagation and the pigs repeated infection, avoiding the high-proof of blue ear disease antibody, resulting in the post-bonding porcum in group delay.
2, the facilities and equipment of the reserve mother pig house
The rear bonded pig house must meet the relevant requirements of the isolated domestication described above. In order to improve the utilization of the rear, it is necessary to have some of the following facilities. 2. Reserve sow tract
The reserve sow is generally started at around 160 days, so it is necessary to use boars to make effective tradition from 160 days. The number of traumatic boars is required to meet the 1st tempting boar every 80-100 times, and it is necessary to use the adult traded boar of the year-old. The traction of the boar should be branched or artificially consolidated once a week to ensure good sex.
In terms of facilities, the BEAR system is confirmed to be effective. Figure 1 is a typical Bear traxicle, both sides are equipped with a two-way entry and exit bar door that can be two-side switches. Two columns are installed in each angle to prevent the back of the mother pigs. At the corner, these columns also provide space for feeding staff to avoid boars. The design of the middle part of the boar is included in the following facilities:
1) 4 to 6 temptation boar bars (60-75CM width, 2.4m long, 1.15m high) have columns on both sides of the boarbar Door (fixed with lock or latch), there is a drinking fountain on both sides, and which direction boars can drink water. The boar is fed with a plate. The drip system is installed in the field is used to cool the boar.
2) 1 hair-free sow fence (1.2m wide, 1.8-2.4m long, 1m high) two-side switch double switch two-side switches.
3) 1 fertilizer pig scale (61cm wide, 1.8-2.4m long, 1M high) open the door, and the reserve sow is weighed.
4) 1 feeding personnel channel (20-30 cm wide, 1.8-2.4m long, 1m high, no steel bibly fixed) is set between the field coil and the boarbar.
When losing, each column has no more than 15 back sows. Repeated personnel carefully observed productionRecommended mother pigs in time. Confirm that the quiet estrus rushes to the estrus sow. The rest of the remaining reserve sows put out a boar with their direct physical contact, recording the reserve sow of the latter estrus. In order to ensure that the initial breeding is in a suitable weight range, the reserve sow that detects estrus can weigh and record it.

2.2 Rear Supply Bar Rear Supply Sigs from the big bars into the limit column, The change in the environment affects the amount of feeding, which in turn affects the reproduction of the rear sow. If the top 1 D ~ 9 D will drive the reserve sow into the limit column, the transition should have a significant impact on the production tribe. Frequently, it is a resend of mother pigs to detect estrus. If it is judged that the next rate of breeding rushes the bonded mother pig to the limit column, it will generally adapt to the limit column for 3 weeks, and the transition is relatively stable.

3, the conclusion
Reasonable design and management of the rear bonded pig house is the key to the success of the modern pig farm. Each production system initiates a detailed reserve sow management process in combination with various factors such as disease prevention and control, breeding, and production management to guide the backpoint of the mother pig.
