Description

Technical Field

[0001] This invention relates to an organic acid powder composition for improving the environment of pig houses. Background Technology

[0002] The quality of the environment has a significant impact on pig farming. If the pigsty and its surrounding environment are not well-maintained, many diseases can occur. To raise pigs well, it is essential to provide them with a comfortable living environment.

[0003] There are generally five factors that affect the pigsty environment: 1. Temperature: Pigs are homeothermic animals and need a suitable temperature environment to be happy and healthy. 2. Humidity: Humidity is also very important for pig growth. High humidity weakens pigs' disease resistance, promotes the growth of pathogenic microorganisms, and makes pigs susceptible to mange, eczema, and respiratory diseases. High humidity can also cause feed to mold, which is very detrimental to pigs' health. 3. Light: A suitable lighting environment can effectively improve feed conversion rate and enhance pigs' growth. 4. Density: Density control is also a key factor directly affecting pigs' growth. Both overcrowding and undercrowding are detrimental to pigs' health. 5. Biocontrol: First, it is necessary to strictly control animals, staff, and personnel entering and leaving the pig farm to reduce transmission routes; second, it is necessary to improve the environment to control and isolate pathogenic microorganisms away from the pigsty.

[0004] Of the factors mentioned above, temperature, light, and density are relatively easy to control and achieve. However, humidity control and biosecurity are more difficult to balance. This is because pigsties must be regularly disinfected to reduce the possibility of disease in pigs. Currently, the common method for disinfecting pigsties with pigs is spraying disinfectant, and to prevent certain diseases, regular, frequent disinfection is often mandated. However, frequent disinfection leads to a persistently damp environment in the pigsty. While quicklime can be used for disinfection, it has no antibacterial or disinfecting effect when applied directly. Quicklime needs to be diluted with water and allowed to react for a period of time to produce slaked lime, which then has some antibacterial properties. Some pig farmers directly sprinkle slaked lime on the ground in the pigpen, which can easily burn the pigs' skin and hind legs. If pigs eat food from the ground, it can also burn their mouths and digestive tract. Furthermore, when spreading lime, the resulting dust can be easily inhaled by pigs, causing coughing and sneezing. The correct method is to thoroughly wash the floor and walls of the pigsty after the pigs have been removed from the pen, then mix purchased quicklime with water to make a 20% lime slurry, and apply it to the walls and floor of the pigsty, especially in crevices and corners. However, this method will obviously also lead to the pigsty becoming very damp.

[0005] In fact, until now there has never been a suitable method that can both reduce humidity and achieve good isolation and disinfection effects.

[0006] We found several comparative documents on treating piggery environments that are quite similar to this application through a novelty search. The first one: CN201810022231.0 "Multifunctional Dry Powder Environmental Modifier and its Preparation Method and Application" discloses a multifunctional dry powder environmental modifier. The formula, calculated by weight percentage, includes: 70-75% montmorillonite, 20-25% zeolite powder, 1-2% vitamin C, 1-3% silicon dioxide, and 2-5% organic acids. This dry powder environmental modifier is used to improve the environment of poultry and livestock farms, reducing humidity, adsorbing harmful gases (such as ammonia and sulfur-containing gases), and simultaneously reducing animal stress.

[0007] Our analysis suggests that this technology is still imperfect: 1. Most importantly, the invention purpose and actual effect of the improver described in this literature only focus on reducing humidity and odor purification in livestock farms, without considering the requirements of biosecurity. 2. The literature uses only a small amount of organic acid, and its technical purpose and function are merely to achieve acid-base neutralization with chemicals such as ammonia and sulfur, solely to reduce harmful gases.

[0008] The second invention, CN201510500190.8, "A Dry Powder Disinfectant Modifier," discloses a dry powder disinfectant modifier comprising an adsorbent, an antibacterial agent, and a regulator. The adsorbent comprises 93%–95% of the total content, the antibacterial agent comprises 3%–5%, and the regulator comprises 1%–4%, all proportions being by weight. The adsorbent is selected from any three or more of montmorillonite, attapulgite, diatomaceous earth, gypsum, alum, activated clay, kaolin, talc, and activated carbon. The antibacterial agent includes natural plant essential oils, and the regulator includes fragrances and borneol. This dry powder disinfectant modifier is used to regulate and improve the environment of pigsties, for piglet delivery, for wound disinfection and antibacterial treatment, and for disinfection and drying of bacterial diarrhea. It is also used to regulate and improve the environment of cattle sheds, chicken sheds, duck sheds, and other livestock pens, for disinfection and antibacterial treatment of animal wounds, and for disinfection and drying of bacterial diarrhea.

[0009] Analysis suggests that this technology is still imperfect: 1. Not every plant essential oil possesses broad-spectrum antibacterial capabilities; in fact, different essential oils only inhibit different bacteria. Therefore, not every essential oil is effective. The broad concept of "essential oil" in the literature makes it difficult to guarantee its effectiveness. 2. Essential oils are highly volatile and unstable. The method of adsorbing essential oils onto particulate carriers is rarely used nowadays. Even when essential oils are formulated into a solution for spraying, the effective time remains too short. Therefore, the method described in the literature, which combines dry powder with essential oils, would require a very large dosage to achieve the desired effect, resulting in high costs and limited practicality. Summary of the Invention

[0010] The purpose of this invention is to provide an organic acid powder composition for improving the pigsty environment, which has both a very good effect of reducing humidity in pigsties and a good effect of inhibiting, isolating and controlling microorganisms. Using the product and method of this invention to improve the pigsty environment can achieve the dual effects of good humidity control and good microbial control.

[0011] The technical solution of the present invention is: an organic acid powder composition for improving the pig house environment, which is uniformly mixed from the following raw materials in the following weight ratio: 70-80 parts of carrier particles, 8-15 parts of organic acid powder, and 3-7 parts of spore-forming beneficial bacteria combination powder.

[0012] Furthermore, the carrier described in this invention is one or more of the following: zeolite powder, montmorillonite, glucose, stone powder, wheat bran, calcium carbonate, and rice husk powder.

[0013] The organic acid powder described in this invention includes one or more of the following: fruit acid, lactic acid, citric acid, oxalic acid, and malic acid.

[0014] The spore-forming beneficial bacteria combination powder described in this invention includes one or more of Bacillus subtilis, yeast, and spore-forming lactic acid bacteria.

[0015] The above-mentioned organic acid powder composition for improving the pigsty environment is prepared by weighing each component raw material according to the ratio, mixing them, and then pulverizing them to 150-300 mesh.

[0016] The product described in this invention is used as follows: apply it manually or with a powder sprayer at a minimum of 20 grams per square meter, at least 4 times a day. Adjust the amount and frequency of application according to the actual pigsty environment. Generally, spray it into the pigsty (pigpen) and onto the pigs.

[0017] The beneficial effects of this invention are as follows:

[0018] Firstly, the composition of this invention includes a high but appropriate amount of organic acid powder and a carrier material with good moisture absorption effect. The carrier and powdered organic acid, etc., can be scientifically and quantitatively sprayed during use to effectively control the humidity of the pig house environment in the pig farm and quickly achieve the required level of coolness and comfort.

[0019] Secondly, the organic acid powder used in this invention is sprayed directly into the pigsty. This has two main effects: firstly, it reduces humidity; secondly, the high concentration of organic acid powder in this invention quickly lowers the pH level of the pigsty environment to below 3, or even lower. A pH below 3 effectively inhibits and isolates many viruses, effectively preventing the spread and occurrence of various viruses. In particular, this invention is highly effective in controlling African swine fever virus (ASF). Current research shows that ASF virus is immediately inactivated when the environmental pH is below 4. Therefore, this invention effectively inhibits and isolates the spread of ASF and other viruses. Furthermore, the organic acid powder adheres to the pigs after spraying, forming a thin layer that adheres for approximately 2-4 hours, acting as a protective film. This not only effectively blocks the spread of ASF virus but also provides a talcum powder-like effect.

[0020] Acidifying agents, including organic acids, are currently mainly used in pig farming in feed. Direct use to improve the pigsty environment is rarely seen; when they are used, they are mostly acidic solutions, and the direct use of acid powder is almost nonexistent. In the existing literature we retrieved, the use of organic acid powder utilizes the ability of organic acids to neutralize chemicals such as ammonia and sulfur, thereby reducing harmful gases. Therefore, this invention uses a large amount of organic acid powder to be directly sprayed into the pigsty without increasing humidity, and it can also effectively lower the environmental pH value. This is a unique and innovative application not currently seen in the industry.

[0021] Thirdly, this invention employs a combination of beneficial bacterial spore powder, which is one of the inventive aspects of its formulation. Maintaining a healthy microecological environment in pigsties is crucial for the health of pig herds. Currently, the existing method for maintaining the dominance of beneficial microorganisms in pigsties involves spraying microbial preparations promptly after disinfection, once the disinfectant's effects have worn off. These supplementary beneficial microorganisms can rapidly multiply within the pigsty, competitively inhibiting the growth of harmful microorganisms, thereby creating a balanced microecological environment throughout the pigsty. However, whether spraying manually or automatically, the timing is difficult to pinpoint precisely, as it's challenging to accurately determine the timeframe between the disinfectant's effects fading and the beneficial bacteria's ability to multiply. Therefore, the current methods for spraying beneficial bacteria in pigsties are not always optimal or timely; sometimes it's too early, and sometimes too late. When the product of this invention is sprayed into the pigsty, the humidity inside the pigsty is quickly controlled to a reasonable standard. Simultaneously, the pH value of the pigsty environment is rapidly reduced to below 3, which effectively inhibits the spread of various viruses. This low pH value also effectively inactivates and inhibits African swine fever virus, and suppresses the growth of most bacteria and fungi, achieving excellent biocontrol results. When the organic acids in the product are consumed and the pH value of the pigsty environment recovers, the spores in the beneficial bacteria powder of this invention will promptly cease dormancy and regain vitality. The core of the spore grows outward into a reproductive body, achieving the immediate reproduction of beneficial bacteria and making them the dominant bacteria, thereby efficiently inhibiting the reproduction of other harmful bacteria. (According to research data, Bacillus has excellent resistance in its spore state, exhibiting good resistance to adverse environments such as high temperature, low temperature, dryness, strong acidity and alkalinity, and chemical drugs. Bacillus can survive in an environment with a pH value of 2.0-3.0, and can grow and reproduce between a pH value of 4.0-5.0, with an optimal pH value of 7-8).

[0022] Fourth, in addition to their main advantages, both the carrier and the organic acid in this invention have excellent odor-removing properties. The carrier generally possesses a certain adsorption capacity, capable of absorbing unpleasant odors; while the organic acid can react with substances that produce ammonia, sulfides, etc., thereby removing ammonia and hydrogen sulfide, among other unpleasant gases. Ammonia is a favorite gas of mosquitoes and flies, so removing it reduces their infestation. Furthermore, the low pH acidification environment and the competitive inhibition of probiotics effectively improve the ecological environment of the pig farm, inhibiting the growth of harmful bacteria and consequently reducing sources of odor. Simultaneously, the probiotics can promptly remove sweat, salt, and metabolic waste from the pig's skin, and have a skin-soothing effect, which is beneficial for cooling in summer.

[0023] In summary, the advantages of this invention are numerous. In particular, the use of organic acid dry powder combined with a carrier and beneficial bacteria spore powder for spraying in pigsties not only effectively reduces humidity but also, through scientific spraying, can completely control humidity within a suitable range. Furthermore, this invention can rapidly lower the pH value of the environment to a low-acidity state, inhibiting the spread and occurrence of most viruses, including African swine fever virus, achieving excellent microbial control. Moreover, while achieving the aforementioned humidity control and microbial control effects, the use of this invention also ensures the immediate proliferation of beneficial bacteria after the inhibitory and disinfecting effects of organic acids diminish, allowing beneficial bacteria to quickly become the dominant flora and suppress the growth of harmful bacteria. This more effectively and for longer maintains a consistently optimal and suitable environment in the pigsty.

[0024] Table 1 below is a comparative test table of the humidity effect of the product of this invention after spraying in actual pigsties:

[0025]

[0026] The tests described in Table 1 above were conducted in two pig pens (pig houses) with essentially the same environmental conditions at a pig farm in Guangxi. The control pen refers to the pig pen that did not use the product of this invention, while the powdered pen refers to the pig pen that used the product of this invention. The method of application was to evenly spray the "organic acid powder composition" of this invention into the pig pen using a dry powder sprayer at a rate of 30 grams per square meter (minimum 20 grams). A hygrometer was used to record the humidity levels (here, humidity refers to relative humidity) in both the control and powdered pens at five different times: before application, 10 minutes after application, 30 minutes after application, 60 minutes after application, and 90 minutes after application. The experimental comparison showed that the humidity in the pig pen sprayed with this product rapidly decreased to below 50% within 10 minutes, and remained below 60% within 90 minutes, and below 55% within 60 minutes. According to existing technical research, the optimal humidity level in a pig house (pig pen) is generally between 50% and 70%. Low humidity can cause dry, cracked skin and dehydration in pigs, reducing their resistance. Low humidity increases the concentration of dust in the air, leading to an increase in respiratory diseases. High humidity can cause pathogenic microorganisms to multiply, triggering skin diseases such as eczema.

[0027] The conclusion is that by spraying the product of this invention in appropriate amounts and at appropriate times, the humidity in the pigsty can be effectively controlled and maintained within a suitable range for a relatively long period of time.

[0028] Table 2 below shows the pH values ​​of the organic acid powder composition of the present invention diluted with water at different dilution ratios:

[0029] Water adding times 3 5 8 10 pH value 1.9 2.3 2.6 2.8

[0030] The pH values ​​of the product of this invention, obtained from tests conducted at different dilution ratios with water, show that even when diluted 10 times, the pH value remains below 2.8. This indicates that after being applied to pigsties, the product can maintain an acidic environment with a pH below 3. Such an acidic environment can inhibit, isolate, and control the spread of most viruses. Current research indicates that viruses cannot survive normally in strongly acidic or alkaline environments. For example, a pH range of 3.23-5.10 provides excellent inhibition and isolation for most viruses. In particular, an acidic environment has a good inhibitory and isolation effect on African swine fever virus (ASFV): the 11th edition of *Swine Diseases* states that ASFV is relatively stable in solutions with a pH of 4.0-10.0, but it is immediately inactivated in serum-free culture media with a pH < 4.0 or > 11.5 (EFSA, 2010). This means that an acidic environment with a pH below 4 effectively inhibits and controls the spread of ASFV. Detailed Implementation
