Description

TECHNICAL FIELD

[0001] The present application relates to the pig feeding technical field, in particular to a feeding method for preventing and controlling African swine fever. BACKGROUND

[0002] African swine fever (ASFV) is caused by African swine fever virus (ASF) infection in domestic pigs and wild boars, which can cause infected pigs to die.

[0003] Controlling the source of infection, cutting off the transmission route and protecting susceptible animals are the basic guidelines for developing infectious disease prevention and control measures. The common method for protecting susceptible animals is vaccination and drug treatment. However, the control of African swine fever vaccine and drugs has not been successfully developed. Under the current conditions, the effective way to control African swine fever can only start from biological safety, control the source of infection, and use some traditional Chinese medicine preparations to enhance the ability of pigs to resist viruses, even if there are virus-carrying pigs, symptoms rarely appear.

[0004] The main food for raising pigs is corn, which comes from thousands of households in the fields, which carries a large amount of dust and virus-carrying pests (there are 383 species of stored grain pests in China, of which 242 species of insects and 141 species of mites), and various pests are also carriers of ASF virus. The general method for removing pests in corn storage is to fumigate with aluminum phosphide and various insecticides, but this fumigation will leave a large amount of fumigation drug residues, which will cause significant harm to the health of pigs.

[0005] Regarding biological safety, it is not difficult to understand. However, in pig production practice, most enterprises (farms) have only done a lot of work on closed management and environmental disinfection, and few pig raising enterprises have carried out purification treatment on corn.

[0006] The basic principle of controlling ASF through some additives is that when the change range of the feeding environment (such as air temperature) is large, the pig's resistance is poor due to stress reaction, and some pigs quickly show ASF symptoms. It is feasible to enhance the resistance of pigs and reduce the incidence of pigs by using some specific traditional Chinese medicine preparations, but the effect of preventing African swine fever is unstable. SUMMARY

[0007] In order to make up for the defects of the existing technology, in order to solve the technical problems that the traditional method of enhancing the resistance of pigs and reducing the incidence of pigs through some specific traditional Chinese medicine preparations can prevent and control African swine fever to some extent, but the effect of preventing African swine fever is unstable, the present application provides a feeding method for preventing and controlling African swine fever.

[0008] The technical problem to be solved by the present application is solved by the following technical scheme:

[0009] A feeding method for preventing and controlling African swine fever, comprising a feeding step, which comprises:

[0010] ①When the average temperature <10℃, in the basic feed added 2-5 kg / t of blue round Zhu Wenjing and 2-5 kg / t of Ephedra soup traditional Chinese medicine preparation together with feeding;

[0011] ②When the average temperature 10℃-25℃, in the basic feed added 2-5 kg / t of blue round Zhu Wenjing and 2-5 kg / t of Huangqi Ciwujia traditional Chinese medicine preparation together with feeding;

[0012] ③When the average temperature >25℃, in the basic feed added 2-5 kg / t of blue round Zhu Wenjing and 2-5 kg / t of Longdan Xiergan soup traditional Chinese medicine preparation together with feeding.

[0013] In the present application, the preparation method of the blue round Zhu Wenjing is as follows: taurine, L-ascorbic acid, fly maggot protein, glucose oxidase are weighed and mixed in a weight ratio of (5-10):(0.5-1):(1-5):(0.1-0.5), then crushed, sieved, and bagged for use.

[0014] Taurine (Tau) is a semi-essential amino acid, widely distributed in various tissues and important organs of the animal body. It is the most abundant free amino acid in the body. Since 1827, taurine was isolated from bovine bile, and in 1975, the first report on the physiological function of taurine appeared. Taurine is synthesized in tissues and cells, and must rely on external transport to blood intake. Studies have shown that taurine has the function of promoting intestinal absorption and improving feed utilization.

[0015] Vitamin C, also known as ascorbic acid, has the important functions of enhancing the body's disease resistance, promoting growth and development, improving immunity, and preventing various diseases. In recent years, vitamin C has been widely used in the prevention and treatment of infectious diseases and has achieved remarkable results.

[0016] Fly maggot protein is rich in antibacterial peptides and plays a very important immunoregulatory role in the immune system. They are not only cellular immune factors, but also have the biological activities of avidin, agglutinin and opsonin. Through rapid response, antibacterial peptides agglutinate exogenous pathogenic microorganisms in the infected local, and then through the connection and mobilization of avidin and opsonin, the entire immune system of the body is fully mobilized to fight against exogenous pathogenic microorganisms.

[0017] Glucose oxidase, most of the beneficial bacteria in the pig intestine are anaerobes, and harmful bacteria are aerobic bacteria, glucose oxidase consumes free radicals to generate hydrogen peroxide which can play a role in resisting harmful viruses, so that the beneficial anaerobic bacteria in the pig body can continuously reproduce, and harmful aerobic pathogenic bacteria such as E. coli can be reduced. In the presence of glucose oxidase, glucose acid is generated, which helps to activate the immune cells in the piglets in the acidic environment, thereby enhancing the immune resistance of the piglets, thereby effectively improving the disease resistance and immune function of the pig.

[0018] Blue round Zhong Wen mainly resists porcine blue ear virus and porcine circovirus, and when the porcine blue ear virus and the porcine circovirus are purified, the ASF can also be better controlled.

[0019] In the application, the preparation method of the Ephedra decoction traditional Chinese medicine preparation is as follows: ephedra, cassia twig, licorice, apricot kernel are weighed respectively according to the weight ratio (90-110):(60-80):(30-50):(350-370), mixed, crushed, sieved, and bagged for use.

[0020] In the application, the preparation method of the Huangqi Shiwujiang traditional Chinese medicine preparation is as follows: Huangqi and Shiwujiang are weighed respectively according to the weight ratio (10-20):(5-10), mixed, crushed, sieved, and bagged for use.

[0021] Huangqi has a very wide effect on the immune system, not only can improve humoral immunity and cellular immunity, but also can promote the generation of immune factors and enhance the function of phagocytes, especially the effect of Huangqi polysaccharide is obviously better than that of saponins and flavonoids. Huangqi polysaccharide can significantly improve the ability of immunosuppressed dogs to produce gamma-interferon (IFN-gamma) and interleukin-2 (IL-2), thereby enhancing their immune function.

[0022] Shiwujiang also has a significant immunomodulatory effect. Its polysaccharide has a good effect on B cell function reconstruction and can reduce or reduce leukopenia caused by cyclophosphamide. Shiwujiang polysaccharide can produce interferon and is a promoter of interferon.

[0023] The compound drug of Huangqi and Shiwujiang can improve the immunity of pigs, enhance the resistance in vivo, and reduce the occurrence of diseases. It is particularly effective in preventing and treating cold and respiratory tract infection diseases.

[0024] In the application, the preparation method of the Longdian Xiigan decoction traditional Chinese medicine preparation is as follows: Longdiancao, Huangqin, Zhizi, Zexie, Mutong, Cheqianzi, Danggui, Shengdihuang, Chaihu, Shenggancao are weighed respectively according to the weight ratio (5-10):(10-15):(10-15):(15-20):(10-15):(10-15):(1-5):(10-15):(5-10):(5-10), mixed, crushed, sieved, and bagged for use.

[0025] In the present application, the mesh size of the sieving is 60-80 mesh.

[0026] In the present application, the corn in the basic feed is pretreated by being stored in a feed processing workshop external isolation room warehouse or a silo for more than 15 days, a circulating ventilation pipeline is arranged in the warehouse to ensure uninterrupted air supply for 24 hours a day, and the air is continuously supplied by mechanical pressure for 15 days.

[0027] The corn silo is installed with a circulating ventilation system, and is started for 24 hours a day, so that the corn in the silo is continuously ventilated, and the continuous ventilation is carried out for 15 days. During the mechanical ventilation, the pressure generated by the fan equipment is used to send low-temperature and low-humidity air from the outside into the corn pile, and to draw out the dirty air with high temperature, high humidity and much dust (containing various virus-carrying insects), which has two effects: one is to promote the heat and moisture exchange between the inside and outside of the corn pile, which can obviously reduce the temperature and moisture of the corn pile, balance the temperature and moisture of the corn pile, delay the increase of corn fat and acid value, and prevent corn from mildewing. The other is to blow away a large amount of dust and insects containing a large amount of viruses, further purify the corn, and prevent the virus from entering the pig farm through the corn raw materials. As long as the corn is fresh, non-mildewed and free of virus-carrying pests, the health of the pigs can be further ensured, and the occurrence of ASF can be prevented.

[0028] In the present application, the feeding method is at least one of sow feeding, piglet feeding, nursery pig feeding and fattening pig feeding.

[0029] In the present application, the pig house nursing step is further included.

[0030] In the present application, the regular vaccination step is further included.

[0031] Compared with the prior art, the present application has the following beneficial effects:

[0032] The traditional Chinese medicine has four properties of "cold, cool, warm and hot", and the principle of application is "treating cold with hot medicine and treating heat with cold medicine". We found that in the pig production practice, most breeding enterprises (farms) do not use different traditional Chinese medicine preparations according to the "cold, cool, warm and hot" characteristics of traditional Chinese medicine under different temperature conditions, which leads to unstable prevention and non-swine flu effect. Under different temperature conditions, the use of different traditional Chinese medicine preparations (Mahuang Decoction, Huangqi Ciqiuga, Longdan Xielan Decoction) can double the antiviral effect, significantly enhance the pig's resistance to disease, prevent and control the occurrence of ASF, and achieve stable prevention and non-swine flu effect.

[0033] The additives used in the present application have two types: one is pure traditional Chinese medicine preparation; the other is several conventional raw materials (taurine, L-ascorbic acid, fly maggot protein, glucose oxidase). These materials have the following common characteristics: safe, no toxic side effects, no palatability problems, have the effects of strengthening healthy energy and eliminating pathogenic factors, have definite curative effect, and are green and safe.

[0034] The present invention installs a circulating ventilation system in the corn silo and keeps it running 24 hours a day for ventilation, with continuous air injection for 15 days. This can not only lower the temperature of the corn pile and reduce the moisture content of the corn, maintaining the freshness and high quality of the corn, but also effectively remove dust and insects carrying various viruses in the corn, ensuring the physical health of the pig herd and preventing the occurrence of ASF.

[0095]

[0096] In 2023, the production results of Xibeiaizhu Pig Farm are shown in Table 6.

[0097] Table 6, production results of Xibeiaizhu Pig Farm in 2023 (400 sows in stock)

[0098]

[0099] As can be seen from Table 6, the survival rate of pigs in Xibeiaizhu Pig Farm in 2022 reached 86.3%, and the feed conversion ratio of market pigs was 2.84:1. In 2022, the survival rate of pigs born in most pig farms was less than 85%, and the feed conversion ratio was more than 3.0:1. The feeding method of Example 3 performs outstandingly.

[0100] Example 4

[0101] In December 2021, the average temperature was <10℃, and 420 pigs (average individual weight 80-90 kg / head) in the No. 1 fattening house of Baoshengyuan Pig Breeding Co., Ltd. appeared sub-health conditions, mainly cough and purple skin. The feeding method for preventing and controlling African swine fever was tried, which mainly includes the following steps:

[0102] 420 heads of fattening pigs were randomly divided into three groups, 140 heads in each group. The first group was fed with 3 kg / t of Lan Yuan Zhu Wenjing and 3 kg / t of Mahuang Decoction of Traditional Chinese Medicine in the basic feed; the second group was fed with 3 kg / t of Lan Yuan Zhu Wenjing and 3 kg / t of Huangqi Cida Five Adder Decoction of Traditional Chinese Medicine in the basic feed; the third group was fed with 3 kg / t of Lan Yuan Zhu Wenjing and 3 kg / t of Longdan Xiergan Decoction of Traditional Chinese Medicine in the basic feed. The preparation methods of the above Lan Yuan Zhu Wenjing, Mahuang Decoction, Huangqi Cida Five Adder Decoction and Longdan Xiergan Decoction are the same as those in Example 2.

[0103] For the above three groups of sub-health fattening pigs, the method specified in the present application was also used, and the unhealthy pigs were eliminated by tooth extraction. The test period was 1 month, and the test results are shown in Table 7. During the test process, the average weekly temperature was <10℃.

[0104] Table 7: The proportion of tooth extraction type pigs in each group in the test of Baoshengyuan Pig Farm in December 2021

[0105]

[0106] As can be seen from Table 7, the proportion of tooth extraction type pigs in the first group is the lowest. This shows that under the condition of an average weekly temperature of less than 10℃, adding Lan Yuan Zhu Wenjing to the basic feed at 3 kg / t of feed, and adding Mahuang Decoction of Traditional Chinese Medicine at 3 kg / t of feed, has the best effect on preventing and controlling non-swine fever.

[0107] Example 5

[0108] In August 2021, the average weekly temperature was >25℃, and 150 heads (average individual weight 50-60 kg / head) of fattening pigs in No. 12 fattening house of Shunwang Pig Breeding Co., Ltd. showed sub-health conditions, mainly cough and purple skin in some pigs. The feeding method for preventing and controlling African swine fever of the present application was used, which mainly includes the following steps:

[0109] The 150 heads of fattening pigs were randomly divided into three groups, 50 heads in each group. The first group was fed with 3 kg / t of Lan Yuan Zhu Wenjing and 3 kg / t of Mahuang Decoction of Traditional Chinese Medicine in the basic feed; the second group was fed with 3 kg / t of Lan Yuan Zhu Wenjing and 3 kg / t of Huangqi Cida Five Adder Decoction of Traditional Chinese Medicine in the basic feed; the third group was fed with 3 kg / t of Lan Yuan Zhu Wenjing and 3 kg / t of Longdan Xiergan Decoction of Traditional Chinese Medicine in the basic feed. The preparation methods of the above Lan Yuan Zhu Wenjing, Mahuang Decoction, Huangqi Cida Five Adder Decoction and Longdan Xiergan Decoction are the same as those in Example 2.

[0110] For the above three groups of sub-health fattening pigs, the method specified in the present application was also used, and the unhealthy pigs were eliminated by tooth extraction. The test period was 1 month, and the test results are shown in Table 8. During the test process, the average weekly temperature was >25℃.

[0111] Table 8, Shunwang pig farm in August 2021 test each group of tooth extraction type treatment pig proportion

[0112]

[0113] From table 8, it can be seen that the test group 3 tooth extraction type treatment pig proportion is the lowest. It shows that under the condition of the average weekly temperature higher than 25℃, adding blue round Zhu Wenjing 3 kg / ton of feed in the basic feed, and adding longdan li gan tang traditional Chinese medicine preparation 3 kg / ton of feed at the same time, the effect of preventing and controlling non-swine fever is the best.

[0114] Example 6

[0115] In October 2022, 10℃< average weekly temperature <25℃, 90 heads (average individual weight 70-80kg / head) in No. 6 fattening house of Hongbo pig breeding Co., Ltd. appeared sub-health condition, mainly part of the pigs coughed, and the skin turned purple. The feeding method for preventing and controlling African swine fever of the application was tried, mainly including the following steps:

[0116] The 90 fattening pigs were randomly divided into 3 groups, 30 heads in each group. The first group was fed with 3 kg / ton of blue round Zhu Wenjing and 3 kg / ton of ma huang tang traditional Chinese medicine preparation in the basic feed; the second group was fed with 3 kg / ton of blue round Zhu Wenjing and 3 kg / ton of huangqi ci wu jia traditional Chinese medicine preparation in the basic feed; the third group was fed with 3 kg / ton of blue round Zhu Wenjing and 3 kg / ton of longdan li gan tang traditional Chinese medicine preparation in the basic feed. The preparation methods of the above blue round Zhu Wenjing, ma huang tang, huangqi ci wu jia and longdan li gan tang are the same as those of example 2.

[0117] For the above three groups of sub-health fattening pigs, tooth extraction type treatment was also taken while the method of the application was tried. Unhealthy pigs were eliminated. The test period was 1 month, and the test results are shown in table 9. During the test process, 10℃< average weekly temperature <25℃.

[0118] Table 9, Hongbo pig farm in October 2022 test each group of tooth extraction type treatment pig proportion

[0119]

[0120] From table 9, it can be seen that the test group 2 tooth extraction type treatment pig proportion is the lowest. It shows that under the condition of 10℃< average weekly temperature <25℃, adding blue round Zhu Wenjing 3 kg / ton of feed in the basic feed, and adding huangqi ci wu jia traditional Chinese medicine preparation 3 kg / ton of feed at the same time, the effect of preventing and controlling non-swine fever is the best.

[0121] The above examples only express the implementation of the application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the application. Any technical solution obtained by equivalent substitution or equivalent transformation should fall within the protection scope of the application.
