A pig farm continuously raises the sow’s health status so that the sow’s performance can be optimally expressed, which can increase productivity and profitability. It also provides a basis for the production of safe and healthy food; a high-yielding sow herd can increase the number of farms The annual slaughter volume can effectively reduce the pig's production costs and increase profitability. Therefore, the establishment of a healthy high-yielding sow herd is the key to achieving the final benefits of a farm. The establishment of a healthy high-yielding sow herd, in addition to environmental factors, but also need to do the following aspects.

Establishing a healthy, high-yielding core group All pig producers understand that the health of a sow herd on a farm directly determines the health of the entire herd, while the health of the herd is a state of dynamic equilibrium, along with the environment. Changes, disturbances of external factors will break their original equilibrium and unpredictable lesions will occur. In order to maintain a strong productivity of the sow herds, the producers had to update the sow herd on schedule. The annual turnover rate of sows in a commercial farm is about 30%, and that of a breeding farm is about 40%. The supplement of a large number of reserve pigs will maintain or enhance the productivity of the herd, but it will also break the original The dynamic balance of herds has brought unforeseen problems to production. It can be seen that the supplementation of spare pigs has become a key factor that restricts the health of the entire herd and requires the carefulness of producers. People usually supplement the reserve pigs in two ways: one is introduced from other fields, and the second is reserved for the field. Most commercial pig farms and a few breeder farms adopt the pattern of introducing excellent pigs from the field when supplementing spare pigs. However, we also understand that while introducing excellent genes, it is also possible to introduce unknown diseases, which will be given later. The production has brought troubles. Many field leaders understand that the detailed analysis of the incidence of pigs is mostly caused by introduction. Therefore, we remind you that the introducer should be careful to introduce. When introducing, not only the performance and shape appearance of the selected breeding pig should be considered, but also the health condition of the breeding pig must be understood. At the same time, the donors of our breeding farms must tell the introducer of their own epidemic prevention treatment without reservation, so that the introduction of the breeding farm can be known to others. Can not be passive. The best way to supplement reserve pigs is to stay in the field. To reserve reserved pigs in this field, we must set up our own purebred breeding group. Therefore, when we introduce the binary system, it is better to introduce a certain number of original breeding pigs to supplement the reserve pigs later. Provide the basis. When introducing new farms, it is necessary to carry out detailed inspections and determine the introduction of farms in consideration of the principles of health and performance. Introduced in the process of introduction based on the size of the herd of pigs with excellent blood breeds, to form a core purebred breeding group. In some old pig farms, when introduced into a core group, some virulent pigs that are unfavorable to the herd should be eliminated through purification or blood tests. After the blood tests, the antibody levels of various diseases in the herd are known. Based on a thorough understanding of the health status of their own herds, introduce excellent pigs that are healthier than their sows, and do a good job of seed selection, segregation, and all necessary immunizations before reintegrating into basic groups. Core populations must also be updated strictly. Grasp the standard of health, detailed file record data.

In the case of grasping the principles of health, we must choose high-yield breeders as females; fast-growing good male boars serve as male parents. At present, the ideological awareness of the pig producers in the South is relatively advanced than that of the North. They can better formulate a scientific introduction plan based on the actual situation in the field. The pig producers in the North often pay too much attention to the pig's body type, which makes the production more difficult and the overall benefit is not high. We recommend long-term determination of introduction from a farm or a company, avoiding multiple introductions as much as possible. To choose a good brand, good service, good reputation of large pig companies. Always put the sow's health and high yield first.

Pig health plans and regular health tests The health-producing sow herd is the basis for normal production. In order to maintain or guarantee long-term health, a strict scientific health plan must be established. In recent years, due to the high density of large-scale pig farms, the prevalence of communicable disease-based morbidity and mortality has increased. Once pathogens invade a susceptible herd, the entire population will soon be involved in causing significant economic losses. The current swine disease has mostly changed from the typical to atypical mild or subclinical type. The new disease continues, and the old disease still exists. Due to the genetic variation or serotype change of pathogens, it is becoming more and more difficult to prevent diseases, and the epidemic of the atypical b Concerns, producers put forward prevention and treatment, because prevention is active, and governance is passive. It is necessary to establish group prevention and group health plans. Therefore, we need to carry out preventive vaccination programs, regularly scheduled drug add-on health plans, parasite detection and control plans, nutritional indicators testing programs.

Fully understand what diseases exist in the surrounding animal husbandry farms, combine the epidemic situation in this field, and then establish a reasonable immunization program, a reasonable choice of vaccines, master the correct vaccine injection method, inoculate according to the prescribed date, 10-14 days after the immunization of pigs should be About 10% of the pig's blood was pumped, serum was separated and examined, serum antibodies were detected to determine the effect of herd immunity, and if necessary, vaccines were given or immunization procedures were adjusted or vaccine manufacturers were changed. Adhere to quarantine to eliminate pigs with virulent poisons. Although the pigs have been rigorously immunized, sometimes the immune antibodies are low or the pigs are in poor condition. They can be infected by the disease. In order to prevent early infection, we must carry out drug care for the pigs.

Specific health plans are as follows:
(1) The perinatal period of sows (1 week before sow and 1 week after childbirth, mix in the following drugs per ton of feed)
180% of the original net 125 grams + doxycycline 100 grams (or 300 grams of aureomycin). 280% of the original net 125 grams of + sulfamethoxazole 500 grams + trimethoprim (TMP) 100 grams + sodium bicarbonate (sodium bicarbonate) 1000 grams.
(2) piglet lactation period 1 open material or drinking water add 80% of the original net 50ppm + amoxicillin 100ppm. After 215 days, 80% of the original composition of the original net was added with 125 ppm of colistin, 50 ppm of zinc and 250 ppm of bacitracin. 3 Add 80% of the original net 125ppm + chlortetracycline 300ppm.
4 Add 80% of the original net 125ppm + amoxicillin 200ppm + sulfamethazine 0ppm + TMP50ppm.
5 Add oral rehydration salt in drinking water, supplement multiple vitamins, acidifiers, digestive enzymes, and probiotics.
(3) Before and after weaning of piglets 1 week before weaning and 2 weeks after the weaning, 80% of the original raw rice was added with 110ppm of net + 400mg of aureomycin. 2 1 week before weaning and 2 weeks after the weaning, 80% of the original progeny was added with net 110ppm of amoxicillin and 175ppm of amoxicillin. 3 One week before weaning and two weeks after weaning, 2% florfenicol 1000 ppm + sulfamethazine 110 ppm + TMP 50 ppm was added to the feed.
4 Limamycin premix (containing 100 mg/kg of benamycin and actinomycin) was fed at 44 ppm. If 1 week before and 2 weeks after delivery, mix by 120 ppm.
6 water-soluble erythromycin 50 grams add 100kg of water, for free drinking, once every 3-5 days, can prevent mycoplasma pneumonia, rickettsia and other diseases.
7 The tylosin tartar 250-500ppm solution is for pigs to drink, mixed with 10-500ppm.
(4) The broth was transferred to 1ppm of the material 1 week before and after the fattening, 1000ppm of 2% florfenicol for 4 days. Prevention is halved. Pregnancy animals are disabled.
0.2% oxytetracycline was added to the material for 7 days.
3 The temperature in the nursery house in winter was low relative to the nursery, and it was transferred to the pig on the 2nd day of the aspirin.
5 Tiamulin 100g + doxycycline 100g (or aureomycin 400g) per ton of feed was used for 1 week. After 1 month, use it again for 1 week.

Do a good job of immunization
1. Each pig farm should develop an immunization program that is more suitable for the field according to its own specific conditions.
2. Poultry farms with poor sanitary conditions should be injected with E. coli genotypes, red fungus bacilli, infectious gastroenteritis, epidemic diarrhea, rotavirus, pulmonary epidemic, erysipelas, streptococcus, infectious pleuropneumonia and other vaccines.
3. The breeding farms should conduct immunization monitoring. After the pigs have been injected with seeds for 10-14 days, they should be sampled and separated from the serum for inspection, checking the growth of the antibodies, and quarantining some infectious diseases.
4. The monitoring of certain diseases can be considered negative without vaccines, especially the attenuated vaccine for blue-eared disease. Do not use it for pregnant sows and boars of reproductive age. For the pig farms that are not seriously polluted, gene-free seedlings should be used. Attention should be paid to the use of gene-free seedlings from established manufacturers to prevent the mixing of gene-free seedlings from multiple manufacturers and prevent the occurrence of genetic recombination.
5. Inactivated vaccines are best to be immunized twice prior to mating, with an interval of 4-6 weeks for enhanced immunity. In case of outbreaks of swine fever, pseudorabies, and parvoviruses, attenuated vaccines should be used as soon as possible for emergency vaccination. After the epidemic is stable or in the old epidemic area, inactivated vaccines are mainly used for purification.

Insect Repellent Programme Parasites such as tapeworms, whipworms, and cockroaches damage the body's immune system. It consumes large amounts of nutrients from pigs and renders pigs immune to dullness. As the resistance of herds is reduced, regular deworming is very important for controlling parasites. The following deworming methods are recommended according to production practice.
1. The sow was subcutaneously injected with ivermectin 0.3 mg/kg body weight 1 month before going to bed and repeated 1 week apart.
2. The boars drive each time in the spring and autumn, with the same amount as above.
3. The weaned piglets were fed with ivermectin powder to feed the pigs for 7 days after being transferred to the nursery and repeated at 1 week intervals. (At this time, the pig has a small body weight, less medication, and good insect repellent.)

Perseverance management
1. Scientific and reasonable staffing Pig production requires the same coordination of staffing, unreasonable staffing, and uncoordinated production. The phenomenon of overstaffing occurs in many people. There are fewer personnel and personnel are shared by the workshops, which is unfavorable for prevention. (Generally equipped with field length, deputy chief, veterinarian, statistics, workshop director), scientific and reasonable staffing is the guarantee for the smooth production of modern pig farms.
2. Scientific and reasonable assessment methods Scientific and reasonable assessment methods are not only the mobilization of employees' enthusiasm, but also a constraint on all employees in their positions. The indicators of assessment are the goals that everyone strives for, the goal is efficiency, the benefits are win-win, the units have benefits, and the employees also have income.
3. Creating a people-centred work environment Leaders should think more about their employees and try to solve practical difficulties and practical problems for them. The real management is not how to manage the employees, but how to solve the worries of employees, how to create a comfortable working environment for employees.
4. The correct guiding ideology and far-sighted development concept
a. Managers should not use economic sanctions to control everything. They should mainly focus on persuasion and education. They should use morals to serve people. Each employee wants to do a good job and must be strong. They all want to move forward. They do not want to go backwards. Doing well does not mean that everything does not work well. Chairman Mao said that "if there is anything wrong, it will be a good comrade." Therefore, our requirement for personnel is that we are not afraid of making mistakes, we are afraid of not changing, and we are not afraid that we will not be afraid of not learning.
b. As a company, we must have a grand blueprint for development. He is the goal of every one of our staff in pursuit and the goal we strive for. There is hope for the future development of the company. There is hope for the employees, and the survival of the company is related to each employee. The development and family. The grand blueprint for the development of enterprises is the driving force for our employees to always be positive.
We have a healthy and productive sow herd, a scientific epidemic prevention health plan to escort, strong management to persist and implement, our farm will not be profitable? (Qilu Livestock News)
