Description

Technical Field

[0001] The invention belongs to the technical field of agricultural environmental protection and resource utilization, and specifically relates to a method for harmless treatment of livestock and poultry excrement. Background Art

[0002] In the modern livestock and poultry breeding industry, especially with the continuous expansion of broiler breeding, manure treatment has become a key issue that needs to be solved urgently. Chicken manure contains about 20% to 30% of nutrients that are not fully digested and absorbed, such as 27% crude protein, 2.4% crude fat, 30% nitrogen-free extract, 5.6% calcium, and a large amount of vitamin B, various essential amino acids, and minerals such as copper, zinc, iron, and manganese. The metabolic energy per kilogram is 10 to 11 megajoules. If these nutrients can be reasonably recycled, it will have a positive impact on the cost control and resource circulation of the animal husbandry industry.

[0003] At the same time, the demand for high-quality fertilizers is also growing in agricultural production. As people pay more attention to food safety and ecological environment, the demand for green and organic agricultural products continues to rise. High-quality organic fertilizers are one of the key factors in producing green and organic agricultural products. There are many kinds of fertilizers on the market, but there are problems such as uneven quality and unbalanced nutrients. Agricultural producers urgently need a reliable, nutritious, safe and environmentally friendly fertilizer to meet the needs of crop growth and improve the yield and quality of agricultural products.

[0004] There are many disadvantages in the traditional way of treating manure and sewage in farms. First, the self-equipped manure and sewage treatment production line often requires a large area of ​​land, which is undoubtedly a huge waste of resources for farms with limited land resources. Second, it is difficult to accurately control the environmental conditions during the fermentation process on the farm, and it is very easy to breed a large number of diseased and insect eggs. These diseased and insect eggs spread in the farm with the flow of air, forming secondary pollution, which greatly increases the probability of animals in the farm being infected with diseases, and seriously threatens the health and growth performance of farmed animals. Third, the cycle of the traditional fermentation method is long, especially in the winter in northern regions, the low temperature environment seriously inhibits the activity of microorganisms, resulting in a slow and incomplete fermentation process, so that the eggs in the manure cannot be completely killed, and the remaining eggs still have the risk of spreading diseases and polluting soil and water sources in the subsequent environment. In addition, the traditional treatment method fails to effectively utilize the rich nutrients remaining in chicken manure. Summary of the invention

[0005] In view of the defects in the prior art, the purpose of the present invention is to provide a method for harmless treatment of livestock and poultry excrement, which can not only remove pathogens and insect eggs in livestock and poultry excrement, but also mature the livestock and poultry excrement and improve the palatability of the livestock and poultry excrement, so that the treated livestock and poultry excrement can be used as a livestock and poultry feed additive. It can also convert the treated livestock and poultry excrement into high-quality fertilizer to meet the needs of agricultural production.

[0006] The objective of the present invention is achieved through the following technical solutions:

[0016] Preferably, the application includes promoting weight gain of livestock and poultry and improving the growth performance of livestock and poultry.

[0017] Preferably, the livestock and poultry include any one or more of cattle, sheep, chickens and pigs.

[0018] The present invention provides a fertilizer, which is livestock manure treated by the treatment method described in the above technical solution. The fertilizer is rich in multiple nutrients and can be used alone and directly applied to the land.

[0019] The present invention provides a fertilizer combination, the main component of which includes livestock manure treated by the treatment method described in the above technical solution.

[0020] The present invention provides application of the fertilizer described in the above technical solution or the fertilizer combination described in the above technical solution in agricultural planting.

[0021] Preferably, the application includes any one or more of promoting the growth of crops, increasing the yield of crops, improving the quality of crops, and enhancing the resistance of crops to pests and diseases and adverse environments.

[0022] The amount of fertilizer applied should be adjusted according to different crops, soil types and fertility conditions. Generally speaking, for vegetable crops, 500kg to 1000kg can be applied per mu of land; for grain crops, 800kg to 1500kg can be applied per mu of land. In actual application, reasonable adjustments can be made based on soil test results and crop growth requirements.

[0023] Preferably, the crops include one or more of vegetables, fruits, flowers, wheat and corn.

[0024] Beneficial effects of the present invention:

[0025] The present invention provides a harmless treatment method for livestock and poultry manure, comprising the following steps: spreading livestock and poultry manure in a microwave treatment container and performing microwave treatment; the power of the microwave treatment is 30 to 300 kW; and the time of the microwave treatment is 3 to 10 minutes. The present invention uses microwaves to generate an ultra-high frequency electric field to treat livestock and poultry manure. The ultra-high frequency electric field acts on livestock and poultry manure, and polar molecules in the livestock and poultry manure produce rapid and continuous vibrations under the influence of the constantly changing direction of the microwave field. This molecular vibration induces intense friction between molecules, thereby generating heat, so that the livestock and poultry manure can be heated from the inside to the outside at the same time, efficiently promoting the evaporation of water therein, and achieving a dehydration and drying effect. In addition, during the heating process, the strong electric field has a destructive effect on the pathogens and insect eggs in the livestock and poultry manure, achieving the purpose of insecticide sterilization. The entire process is simple and efficient, and does not require complex mechanical transmission and large-scale fermentation sites. The present invention adopts the above-mentioned treatment method to treat chicken manure. The unique physical properties of microwaves can instantly heat up the chicken manure material without any heat transfer medium. The heating speed can be tens or even hundreds of times faster than that of traditional heating methods, and uniform heating is achieved inside the material. This is due to the automatic balancing performance of microwaves, which effectively avoids the problem of local overheating or local underheating that is easy to occur in traditional heating methods. In terms of insecticide sterilization, by accurately controlling the irradiation time, power and other parameters of microwaves, a sterilization rate of more than 86% and an insecticide effect of 100% can be achieved within a relatively short treatment time. In terms of nutrient retention, due to the extremely short treatment time, the nutritional components in chicken manure, such as crude protein, are rarely lost, and the crude protein content before and after treatment is 36.6% and 35% respectively. At the same time, microwave treatment also gives chicken manure a significant deodorization and maturation effect, greatly improving its palatability, so that it can be recycled as a potential feed resource in animal husbandry. At the same time, microwave-treated feces can also be used as fertilizer in agricultural production.

[0026] Furthermore, the present invention successfully solves the problem of large production line area in traditional farm manure treatment through microwave technology, because microwave equipment is relatively compact and does not require large-scale fermentation site layout; for example, in the factory, manure tanks, horizontal conveyors, spiral conveyors, microwave equipment, etc. are reasonably arranged in a large factory, and the color steel room wall plays a protective role. The entire treatment process is compact and orderly, and space is effectively utilized. The risk of secondary pollution caused by the breeding of pests and eggs during fermentation on the site is effectively eliminated, and the pest and egg sterilization function of microwaves is used to kill the bacteria and eggs at the source of treatment; the fermentation cycle is greatly shortened, the adverse effects of low temperatures on fermentation in the north in winter are overcome, and efficient treatment of manure and sewage can be ensured throughout the year.

[0027] The treatment method of the present invention realizes the diversified application of materials after manure treatment, especially in the field of animal husbandry feed. The large amount of nutrients remaining in chicken manure due to the characteristics of the chicken digestive tract are fully exploited, and the products after microwave treatment are recycled as partial feed substitutes, which not only reduces the feed cost of animal husbandry, but also improves the recycling rate of resources. And it is better than the traditional treatment method in all performance indicators. In terms of heating speed, the rapid heating characteristics of microwaves are utilized to instantly penetrate the material to achieve rapid heating; in terms of insecticide and sterilization rate, with the help of the powerful biological effect of microwave electric field, a nearly perfect insecticide and sterilization effect is achieved; in terms of nutrient loss control, the nutrient loss is controlled to a minimum by means of extremely short processing time; in terms of deodorization and improvement of palatability, the special effect of microwaves is used to transform chicken manure from a foul smell to a feed resource with a certain palatability, opening up a new way for the harmless treatment and resource utilization of livestock and poultry manure.

[0028] At the same time, microwave treatment can kill harmful bacteria and parasites in manure and reduce potential harm to crops and soil. Moreover, it can promote the decomposition and transformation of organic matter in manure to a certain extent, making it easier for crops to absorb and utilize. Proper application in farmland can provide rich nutrients for crops, promote crop growth, and improve agricultural production efficiency.

[0029] The chicken manure treated by the treatment method can effectively increase the organic matter content in the soil, improve the soil structure, promote the reproduction and activity of soil microorganisms, and create a fertile and vibrant soil environment for the growth of crops. In terms of nutrient supply, it can stably and continuously provide crops with key nutrients such as nitrogen, phosphorus, and potassium that are necessary for their growth, ensure the nutritional needs of crops at various growth stages, and help them thrive.

[0030] Compared with traditional fertilizers, the chicken manure treated by the treatment method of the present invention has significant advantages in safety. After microwave treatment, the pathogens, insect eggs and harmful microorganisms in the manure are completely killed, which greatly reduces the risk of crops being attacked by pests and diseases, reduces the use of chemical pesticides, and produces greener and safer agricultural products. In terms of environmental protection, the efficient recycling of livestock and poultry manure is achieved, the pollution of waste to the environment is reduced, and the agricultural ecosystem is promoted to develop in a greener and more sustainable direction, which opens up a new way of resource utilization for agricultural production and becomes a strong support for the sustainable development of agriculture.

[0053] The poultry and livestock manure used in the following examples and comparative examples is the same batch of raw chicken manure. In the specific experimental process, the same batch of chicken manure was mixed evenly and then divided into several portions for the following examples and comparative examples.

[0054] The following embodiment is a processing flow for harmless treatment of livestock and poultry manure: chicken manure is produced in a chicken house, first collected by a manure pit, and then transported to a microwave device by a horizontal conveyor and a screw conveyor. During this process, a biological deodorization operation is performed simultaneously.

The entire processing process is strictly controlled to ensure that the final product has practical value.

[0055] Example 1

[0056] A method for harmless treatment of livestock and poultry excrement, the steps are as follows:

[0057] Collect fresh manure from broiler farms and transport it to a specially designed microwave treatment area. This area must have good ventilation conditions and necessary protective facilities to ensure the safety of operators and the hygiene of the environment.

[0058] The initial moisture content of the collected chicken manure is controlled at 40%, and then the chicken manure is evenly spread in an alumina ceramic microwave treatment container with a spreading thickness of 4 cm. The container can withstand microwave radiation and has no adverse chemical reaction to the chicken manure.

[0059] The microwave equipment was turned on, the microwave power was set to 150 kW, the processing time was set to 8 minutes, and the chicken manure was subjected to microwave treatment. During the microwave irradiation process, the temperature change inside the chicken manure was monitored in real time by a temperature sensor. When the predetermined processing time was reached, the microwave treatment was completed. The microwave equipment was turned off.

[0060] After the microwave treatment is completed, the treated chicken manure is obtained.

[0061] Example 2

[0062] A method for harmless treatment of livestock and poultry excrement, the steps are the same as those in Example 1, the only difference being that the thickness of the chicken manure spread is 3 cm. When the predetermined treatment time is reached, the microwave treatment is completed.

[0063] Example 3

[0064] A method for harmless treatment of livestock and poultry manure, the steps are the same as those in Example 1, the only difference being that the thickness of the chicken manure spread is 5 cm. When the predetermined treatment time is reached, the microwave treatment is completed.

[0065] Comparative Example 1

[0066] A method for harmless treatment of livestock and poultry manure, the steps are the same as those in Example 1, except that the thickness of the chicken manure spread is 2 cm. When the predetermined treatment time is reached, the microwave treatment is completed.

[0067] Comparative Example 2

[0068] A method for harmless treatment of livestock and poultry excrement, the steps are the same as those in Example 1, except that the thickness of the chicken manure spread is 6 cm. When the predetermined treatment time is reached, the microwave treatment is completed.

[0069] Application Example 1

[0070] Verification of the Effects of the Treatment Methods Described in Examples 1 to 3 and Comparative Examples 1 to 2

[0071] 1. Install thermocouple temperature sensors on the surface and inside of the chicken manure layer, connect them to a data logger for temperature monitoring, record the temperature changes throughout the process, and record the surface temperature and internal temperature of the chicken manure after microwave treatment. Count the number of bacteria in the chicken manure after microwave treatment by plate counting method. Determine the crude protein content in the chicken manure after treatment by using the Kjeldahl method. Determine the residual moisture content of the chicken manure after treatment by using the oven drying method.

[0072] The verification results of the treatment methods described in Examples 1 to 3 and Comparative Examples 1 to 2 are shown in Table 1.

[0073] Table 1 Verification results of the treatment methods described in Examples 1 to 3 and Comparative Examples 1 to 2

[0074]

[0075] As can be seen from Table 1, the chicken manure paving thickness in the embodiment is 3 to 5 cm, and the appropriate thickness ensures temperature uniformity and high sterilization rate while retaining nutrients. Comparative Example 1: Thickness is 2 cm, water content is 40%, heating power is 150 kW, heating time is 8 min, internal temperature is about 120 ° C, and surface temperature is about 90 ° C. Too thin thickness causes the internal temperature to rise too fast and too high, which may exceed the safe temperature to ensure the functionality of the product, which is not conducive to the retention of nutrients, etc., and there is uncertainty in the inactivation effect of bacteria. The number of bacteria in each gram of chicken manure is about 800. Comparative Example 2: Thickness is 6 cm, water content is 40%, heating power is 150 kW, heating time is 8 min, internal temperature is about 60 ° C, and surface temperature is about 40 ° C. Too thick thickness makes the temperature too low, the treatment effect is poor, and the crude protein content after treatment is about 29.8%. Lower temperatures may cause some proteins to be insufficiently denatured or incompletely degraded.

[0076] 2. Test the organic matter, total nutrients, pH, and harmful substances in the treated chicken manure. Organic matter detection method: potassium dichromate volumetric method-external heating method. According to the national standard: "Organic Fertilizer" (NY 525-2021), the mass fraction of organic matter in organic fertilizer (on a dry basis) should be ≥30%. Total nutrients (N+P2O5+K2O), detection method: total nitrogen: Kjeldahl method; phosphorus: ammonium molybdate spectrophotometry; potassium: flame photometry; according to the national standard: "Organic Fertilizer" (NY 525-2021), the mass fraction of total nutrients (N+P2O5+K2O) (on a dry basis) should be ≥4.0%. pH detection method: direct measurement with a pH meter; according to the national standard: "Organic Fertilizer" (NY 525-2021), the pH of organic fertilizer should be between 5.5-8.5. Method for detecting total arsenic: atomic fluorescence spectrometry or inductively coupled plasma mass spectrometry (ICP-MS); National standard: "Organic Fertilizer" (NY 525-2021) stipulates that the mass fraction of total arsenic (As) in organic fertilizer (on a dry basis) should be ≤15mg / kg. Method for detecting total mercury: cold atomic absorption spectrometry or atomic fluorescence spectrometry; National standard: "Organic Fertilizer" (NY525-2021) stipulates that the mass fraction of total mercury (Hg) in organic fertilizer (on a dry basis) should be ≤2mg / kg. Method for detecting total lead: atomic absorption spectrometry or inductively coupled plasma mass spectrometry (ICP-MS); National standard: "Organic Fertilizer" (NY 525-2021) stipulates that the mass fraction of total lead (Pb) in organic fertilizer (on a dry basis) should be ≤50mg / kg. Total chromium detection method: diphenylcarbazide spectrophotometry or inductively coupled plasma mass spectrometry (ICP-MS); National Standard: "Organic Fertilizer" (NY 525-2021) stipulates that the mass fraction of total chromium (Cr) in organic fertilizer (on a drying basis) should be ≤150mg / kg. Fecal coliform group detection method: multiple tube fermentation method or membrane filter method; National Standard: "Organic Fertilizer" (NY 525-2021) stipulates that the fecal coliform group in organic fertilizer should be ≤100 / g. Ascaris eggs, detection method: saturated sodium nitrate flotation method or centrifugal sedimentation method; National Standard: "Organic Fertilizer" (NY 525-2021) stipulates that the mortality rate of ascaris eggs in organic fertilizers should be ≥95%, and no live ascaris eggs should be detected.

[0077] The results are shown in Table 2.

[0078] Table 2 Verification results of the treatment methods described in Examples 1 to 3 and Comparative Examples 1 to 2

[0079]

[0080]

[0081] As can be seen from Table 2, the organic matter content and total nutrients in the chicken manure treated by the treatment method of the present invention are higher than those in Comparative Examples 1 and 2, indicating that when the paving thickness is 3 to 5 cm, it is beneficial to maintain the organic matter content in the chicken manure. Comparative Example 2: The thickness is 6 cm, the water content is 40%, the heating power is 150 kW, the heating time is 8 min, the internal temperature is about 60 ° C, and the surface temperature is about 40 ° C. The thickness is too thick, so the temperature is too low, the treatment effect is not good, and the organic matter content is about 56%. The lower temperature may cause some treatment processes to be insufficient, and the impact on organic matter is also more complicated. The thickness is too thick, so the temperature is too low, the treatment effect is not good, and the total nutrient content is about 9.0%. The lower temperature may cause some treatment processes to be insufficient, and the impact on total nutrients is also more complicated.

[0082] Example 4

[0083] A method for harmlessly treating livestock and poultry excrement, the steps are the same as those in Example 1, except that the initial moisture content of chicken manure is 30%, and the microwave treatment time is 8 minutes.

[0084] Example 5

[0085] A method for harmlessly treating livestock and poultry manure, the steps are the same as those in Example 1, the only difference being that the initial moisture content of the chicken manure is 50%, and the microwave treatment time is 8 minutes.

[0086] Example 6

[0087] A method for harmlessly treating livestock and poultry excrement, the steps are the same as those in Example 1, the only difference being that the initial water content of the chicken manure is 70%, and the microwave treatment time is 8 minutes.

[0088] Comparative Example 3

[0089] A method for harmlessly treating livestock and poultry manure, the steps are the same as those in Example 1, the only difference being that the initial water content of the chicken manure is 20%, and the microwave treatment time is 8 minutes.

[0090] Comparative Example 4

[0091] A method for harmlessly treating livestock and poultry manure, the steps are the same as those in Example 1, the only difference being that the initial water content of the chicken manure is 80%, and the microwave treatment time is 8 minutes.

[0092] Application Example 2

[0093] Verification of the Effects of the Treatment Methods Described in Examples 4 to 6 and Comparative Examples 3 to 4

[0094] 1. Record the surface temperature and internal temperature of the chicken manure after microwave treatment. Count the number of bacteria in the chicken manure after microwave treatment. Determine the crude protein content in the chicken manure after treatment.

[0095] The verification results of the treatment methods described in Examples 4 to 6 and Comparative Examples 3 to 4 are shown in Table 3.

[0096] Table 3 Verification results of the treatment methods described in Examples 4 to 6 and Comparative Examples 3 to 4

[0097]

[0098] It can be seen from Table 3 that the initial moisture content will affect the treatment effect of chicken manure. When the initial moisture content is 30% to 70%, the crude protein loss rate of the treated chicken manure is low, and the number of bacteria and moisture content in the chicken manure can be significantly reduced. Comparative Example 3: Thickness is 4cm, moisture content is 20%, heating power is 150kW, heating time is 8min, internal temperature is about 75℃, and surface temperature is about 55℃. The moisture content is too low, and the crude protein content after treatment is about 29.6%. Low moisture content makes protein more vulnerable to damage during heating. Comparative Example 4: Thickness is 4cm, moisture content is 80%, heating power is 150kW, heating time is 8min, internal temperature is about 100℃, and surface temperature is about 80℃. If the moisture content is too high, although it absorbs more energy, it may cause local overheating and overall unevenness, which is not conducive to the reasonable treatment of chicken manure. The number of bacteria in each gram of chicken manure may be around 1000.

[0099] 2. The organic matter, total nutrients, pH value and harmful substances in the treated chicken manure were tested. The results are shown in Table 4.

[0100] Table 4 Verification results of the treatment methods described in Examples 4 to 6 and Comparative Examples 3 to 4

[0101]

[0102] It can be seen from Table 4 that when the initial moisture content is 30% to 70%, the organic matter and total nutrient loss of the treated chicken manure is less. Comparative Example 3: Thickness is 4cm, moisture content is 20%, heating power is 150kW, heating time is 8min, internal temperature is about 75℃, and surface temperature is about 55℃. The moisture content is too low, and the organic matter content in every 100g of chicken manure is about 55g. Low moisture content causes relatively large damage to organic matter during heating. The moisture content is too low, and the total nutrient content is about 8.9%. Low moisture content causes relatively large damage to total nutrients during heating.

[0103] In summary, the initial moisture content of chicken manure is controlled between 30% and 70%. Chicken manure can quickly generate sufficient vapor pressure under microwave radiation, thereby increasing the evaporation rate of water and effectively shortening the processing time. Too high a moisture content (such as greater than 70%) will lead to excessive consumption of microwave energy on water evaporation, which may require extended processing time and increase the thermosensitive loss of nutrients. Therefore, when the initial moisture content of livestock and poultry manure to be processed is higher than 70%, it is recommended to pre-dehydrate it. Natural air drying or mechanical dehydration can be used to reduce the moisture content to a reasonable range. When the initial moisture content of livestock and poultry manure to be processed is lower than 30%, it can be appropriately sprayed with water before microwave treatment to increase the moisture content to the recommended range and improve the overall uniformity and efficiency of microwave treatment.

[0119] Verification of the Effects of the Treatment Methods of Examples 7 to 11 and Comparative Examples 5 to 6

[0120] 1. Record the surface temperature and internal temperature of the chicken manure after microwave treatment. Count the number of bacteria in the chicken manure after microwave treatment. Determine the crude protein content in the chicken manure after treatment.

[0121] The verification results of the treatment methods described in Examples 7 to 11 and Comparative Examples 5 to 6 are shown in Table 5.

[0122] Table 5 Verification results of the treatment methods described in Examples 7 to 11 and Comparative Examples 5 to 6

[0123]

[0124] 2. The organic matter, total nutrients, pH value and harmful substances in the treated chicken manure were tested. The results are shown in Table 6.

[0125] Table 6 Verification results of the treatment methods described in Examples 7 to 11 and Comparative Examples 5 to 6

[0126]

[0127] It can be seen from Tables 5 and 6 that within the power range of 30 to 300 kW, microwave energy can penetrate the chicken manure layer, achieve synchronous heating and evaporation of water inside and outside, and the efficient sterilization effect ensures the safety of chicken manure while keeping the nutrients intact. Comparative Example 5: Thickness of 4 cm, water content of 40%, heating power of 20 kW, heating time of 10 min, internal temperature of about 50 ° C, and surface temperature of about 30 ° C. The power is too low, and the crude protein content after treatment is about 30.0%. The effect of lower temperature and long heating on crude protein is relatively small, but the treatment effect is not good. At the same time, the power is too low, and the organic matter content is about 57%. The effect of lower temperature and long heating on organic matter is relatively small, but the treatment effect is not good. The power is too low, and the total nutrient content is about 9.1%. The effect of lower temperature and long heating on total nutrients is relatively small, but the treatment effect is not good. Comparative Example 6: Thickness of 4 cm, water content of 40%, heating power of 400 kW, heating time of 3 min, internal temperature of about 130 ° C, and surface temperature of about 100 ° C. If the power is too high and the temperature is too high in a short time, it will exceed the reasonable range, which may destroy the beneficial components in the chicken manure and make it difficult to process. The number of bacteria in each gram of chicken manure may be around 1,200.

[0128] Too high power, when the power is set to 400 kilowatts, the processing time is shortened to 3 minutes. Excessive temperature causes the degradation of protein and other heat-sensitive nutrients, and the nutritional value decreases. High temperature treatment causes excessive changes in the structure of chicken manure, which may cause coking. The nutrient loss rate increases after treatment. The sterilization rate decreases. The effectiveness of the recommended power range (30-300kW) is further verified, which can achieve efficient sterilization and dehydration while ensuring nutrients. Too high or too low power will lead to adverse effects, such as nutrient loss, reduced palatability or insufficient sterilization effect. Therefore, the recommended microwave power range (30-300kW) can achieve efficient sterilization and dehydration while ensuring minimal nutrient loss. The present invention overcomes the adverse effects of too high or too low power by optimizing the power parameters, and provides an efficient, safe, and nutrient-well-maintained chicken manure treatment solution. The advantage of this technical solution lies in its precise parameter setting to ensure the optimization of the treatment effect.

[0129] Example 12

[0130] A method for harmless treatment of livestock and poultry excrement, the steps are as follows:

[0131] Collect fresh manure from broiler farms and transport it to a specially designed microwave treatment area. This area must have good ventilation conditions and necessary protective facilities to ensure the safety of operators and the hygiene of the environment.

[0132] The initial moisture content of the collected chicken manure was controlled at 30%, and then the chicken manure was evenly spread in an alumina ceramic microwave treatment container with a spreading thickness of 3 cm.

[0133] The microwave equipment was turned on, the microwave power was set to 300 kW, the processing time was set to 5 minutes, and the chicken manure was subjected to microwave treatment. During the microwave irradiation process, the temperature change inside the chicken manure was monitored in real time by the temperature sensor. When the predetermined processing time was reached, the microwave treatment was completed. The microwave equipment was turned off.

[0134] After the microwave treatment is completed, the treated chicken manure is obtained.

[0149] Comparative Example 7: Thickness of 4cm, water content of 80%, heating power of 200kW, heating time of 5min, internal temperature of about 110℃, surface temperature of about 90℃. Due to the matching of parameters such as water content, power and time, the temperature exceeds the reasonable range, which is not conducive to the treatment of chicken manure. The number of bacteria in each gram of chicken manure may be around 1000. Comparative Example 7: Thickness of 4cm, water content of 80%, heating power of 200kW, heating time of 5min, internal temperature of about 110℃, surface temperature of about 90℃. Due to the matching of parameters such as water content, power and time, the temperature exceeds the reasonable range, which is not conducive to the treatment of chicken manure, and the crude protein content after treatment is about 29.6%. Comparative Example 7: Thickness of 4cm, water content of 80%, heating power of 200kW, heating time of 5min, internal temperature of about 110℃, surface temperature of about 90℃. Due to the matching of parameters such as water content, power and time, the moisture content is about 7.5%. The unreasonable combination of parameters makes it impossible to effectively remove moisture.

[0150] Comparative Example 8: thickness 3 cm, water content 60%, heating power 20 kW, heating time 10 min, internal temperature about 60 ° C, surface temperature about 40 ° C. The poor combination of parameters resulted in too low a temperature and the chicken manure could not be effectively treated. The crude protein content after treatment was about 29.7%.

The organic matter content in every 100g of chicken manure was about 56g, and the total nutrient content was about 9.0%.

[0155] Application Example 5

[0156] Experimental study on the feeding effect of chicken manure obtained by the treatment method described in Example 1 as a feed additive

[0157] The effects of chicken manure treated by the treatment method of the present invention as a feed additive on the growth performance and health of livestock such as beef cattle and sheep are evaluated. By optimizing the mixing ratio, the best use of chicken manure as feed is determined to improve breeding benefits and resource utilization efficiency.

[0158] Experimental Design and Methods

[0159] 1. Test subjects:

[0160] Thirty beef cattle and 30 sheep of similar weight and health status were selected and randomly divided into three groups: beef cattle control group; beef cattle experimental group A; beef cattle experimental group B; sheep control group; sheep experimental group A; and sheep experimental group B.

[0161] 2. Feed formula:

[0162] The beef cattle control group used conventional feed, Inmel No. 1013 cattle feed, without adding the feed additive of Example 11.

[0163] Beef cattle experimental group A: The feed additive of Example 11 was mixed into regular feed at a ratio of 5%.

[0164] Beef cattle experimental group B: the feed additive of Example 11 was mixed into conventional feed at a ratio of 10%. Sheep control group: conventional feed, Inmel Lamb Duowang high-efficiency sheep feed, was used without adding the feed additive of Example 11.

[0165] Sheep experimental group A: The feed additive of Example 11 was mixed into regular feed at a ratio of 5%.

[0166] Sheep experimental group B: The feed additive of Example 11 was mixed into regular feed at a ratio of 10%.

[0167] 3. Rearing conditions:

[0168] Each group was kept under the same environmental conditions to ensure that there were no other variables affecting the environment.

[0169] The experimental period was set to 90 days.

[0170] 4. Measurement indicators:

[0171] (1) Growth performance:

[0172] Weigh the children every two weeks and record the weight changes.

[0173] The average daily gain (ADG) was calculated.

[0174] (2) Health status:

[0175] Conduct regular health checks and record morbidity rates.

[0176] (3) Observe changes in appetite and behavior.

[0177] (4) Feed conversion rate:

[0178] Calculate the feed conversion ratio (FCR): FCR = feed intake / body weight gain.

[0179] 5. Results and analysis

[0180] (1) Growth performance: The changes in body weight of each test group are shown in Table 9 below.

[0181] Table 9 Weight changes in each experimental group (mean)

[0182]

[0183]

[0184] It can be seen from Table 9 that the use of microwave-treated chicken manure as a feed additive for beef cattle can achieve a growth-promoting effect similar to that of conventional feed. Microwave-treated chicken manure can be used to feed beef cattle.

[0185] (2) Feed conversion ratio (FCR): The feed conversion ratio of each experimental group is shown in Table 10 below.

[0186] Table 10 Feed conversion rate of each test group

[0187] Group Feed conversion rate Beef cattle control group 3.2 Beef cattle experimental group A 2.9 Beef cattle experimental group B 2.5 Sheep control group 3 Sheep experimental group A 2.7 Sheep experimental group B 2.3

[0188] It can be seen from Table 10 that the feed conversion rates of experimental group A and experimental group B of beef cattle and sheep are lower than those of the control group, among which the feed conversion rate of experimental group B is the lowest, indicating that after adding a specific proportion of feed additives, the efficiency of converting feed into weight growth is the highest.

[0189] (3) Health status:

[0190] No major health problems occurred in any group, and the morbidity rate was low.

[0191] In the experimental groups of beef cattle and sheep:

[0192] Beef cattle experimental group A:

[0193] During the trial, one beef cattle showed digestive discomfort, with an incidence of about 20%. In the fourth week, the beef cattle had mild diarrhea, which was probably caused by accidental factors, such as water cleanliness, but it quickly returned to normal. Throughout the trial, the beef cattle's appetite was relatively stable, and their feeding behavior was normal, without picky eating or food refusal. The daily activity was moderate, and no abnormal behavior was observed, such as irritability, lethargy, etc.

[0194] Beef cattle experimental group B:

[0195] One beef cattle had health problems, with an incidence rate of 20%. At the beginning of the experiment, this beef cattle had mild digestive discomfort in the second week, which was manifested by a slight decrease in the frequency of rumination. Considering that this group added feed additives made of chicken manure, it is speculated that this may be a short-term adaptation process for the animal to the new feed ingredients, and then gradually returned to normal. In terms of appetite, a small number of individuals had a slight decrease in feed intake at the beginning, but it returned to normal over time. In terms of behavior, when digestive discomfort occurred, the activity of this beef cattle decreased slightly, and the activity returned to normal after recovery. The overall fecal status of the herd is normal, but the amount of feces produced by the herd is slightly more than that of other groups.

[0196] Sheep experimental group A:

[0197] One sheep had health problems, with an incidence rate of about 20%. One sheep had mild abdominal distension in the fourth week, which may be related to accidentally eating too much soybean meal. After adjusting the feed amount, it returned to normal. The sheep's appetite was generally good, and the feeding speed and feed intake were relatively stable, without loss of appetite. The behavior was normal, with regular daily activities and rest time, and no abnormal behaviors such as chewing the railings and frequent bleating.

[0198] Sheep experimental group B:

[0199] One sheep had health problems, with an incidence rate of about 20%. At the beginning of the experiment, the sheep developed symptoms of digestive discomfort in the second week, manifested as thinner feces and slower feeding speed. Considering that the feed additives made from chicken manure may have differences in composition from the original feed, the animal may need a certain amount of time to adapt and then gradually recover. In terms of appetite, the overall feed intake decreased to a certain extent in the early stage, and then gradually recovered. In terms of behavior, the sheep that experienced digestive discomfort in the early stage had reduced activity, and the activity returned to normal after recovery. During the entire experiment, the amount of feces in the sheep experimental group B was relatively large, and the feces was relatively thin in the early stage.

[0200] Control group:

[0201] Beef cattle control group:

[0202] Two beef cattle had health problems, with an incidence of about 40%. One of the beef cattle had acid reflux in the fourth week, which may be caused by long-term consumption of traditional soybean meal and corn feed. In the sixth week, one beef cattle had diarrhea, which was speculated to be caused by improper feed storage. The appetite and behavior of beef cattle are sometimes affected by health problems, and they are not active in eating and have reduced activity. The feces are also unstable, and sometimes there are loose stools.

[0203] Sheep control group:

[0204] One sheep had health problems during the trial, with an incidence rate of about 20%. One sheep had mild diarrhea in week 6, probably due to contaminated drinking water. The appetite and behavior of sheep will be affected to a certain extent when health problems occur, and the activity level will also be reduced. The feces sometimes appear abnormal.

[0205] Through the above observations and records, it can be seen that in the experimental groups that added feed additives in different proportions (including feed additives made from chicken manure), although some individuals experienced some digestive discomfort symptoms in the early stage, the overall incidence rate was low, and most individuals were able to adapt over time. There were no major problems with the health status of the experimental groups, and to a certain extent, adding feed additives made from chicken manure may play a certain role in reducing problems such as acid reflux caused by traditional feeds.

[0206] Based on the experimental data, it is recommended to use treated chicken manure as a feed additive in actual breeding, and adjust the proportion according to the specific situation to achieve the best economic benefits and resource utilization effect.

[0207] It should be noted that in actual applications, the use of chicken manure to make feed additives must strictly follow relevant hygiene and safety standards to ensure animal health and food safety.

[0208] Application Example 6

[0209] 1. Experimental Setup

[0210] Effects of different proportions of microwave chicken manure fertilizer on the growth of Chinese cabbage

[0211] Test subjects: Select a number of pakchoi seeds with similar growth conditions. Prepare enough planting containers, ensuring that the container size, soil matrix and other conditions are consistent.

[0212] Fertilizer formula:

[0213] Test group A: 18g of Nongmanguan compound fertilizer and 2g of chicken manure obtained in Example 1 were mixed evenly and then applied, that is, 10% of chicken manure obtained in Example 1 was added to the fertilizer. 10 Chinese cabbages were planted.

[0214] Test group B: 16g of Nongmanguan compound fertilizer and 4g of chicken manure obtained in Example 1 were mixed evenly and then applied, that is, 20% of chicken manure obtained in Example 1 was added to the fertilizer. 10 Chinese cabbages were planted.

[0215] Control group: conventional fertilizer, 20g of Nongmanguan compound fertilizer, without microwave chicken manure. 10 Chinese cabbages were planted.

[0216] Planting conditions:

[0217] Plant in the same greenhouse environment and keep temperature, humidity, light and other conditions relatively stable.

[0218] Use the same soil substrate and planting container to ensure that each bok choy plant has enough space to grow.

[0219] Sow and manage according to normal planting methods, including regular watering and weeding.

[0220] 2. Measurement indicators and parameters

[0221] Description of growth:

[0222] Observe and record the appearance of the pakchoi at different growth stages, including leaf color, plant morphology, etc. For example, describe whether the leaves are green and upright, whether the plant is strong, etc.

[0223] The growth rate of Chinese cabbage was recorded, and the time required from sowing to germination and growth to the stage where fresh weight could be measured was observed.

[0224] Fresh weight:

[0225] When the Chinese cabbage is one month old, carefully harvest each one to avoid damaging the plants.

[0226] Use an electronic scale to accurately weigh the fresh weight of each Chinese cabbage, record the data and perform statistical analysis.

[0227] The average fresh weight of the control group, experimental group A and experimental group B was calculated, and the effects of different fertilizer formulas on the fresh weight of pakchoi were compared.

[0228] 3. Experimental results:

[0229] (1) Description of growth

[0230] During the entire growth process, the leaves of the Chinese cabbage in the control group were light green at first, and gradually turned dark green as they grew, but the overall color was slightly dull. The plant was relatively small and the leaves were relatively thin. The growth rate was relatively slow, and it took about 3 days from sowing to germination, and it took a month to grow to the measurable fresh weight stage. During this period, the growth trend was relatively stable, but there was no obvious rapid growth stage.

[0231] The leaves of the Chinese cabbage in the experimental group A showed a brighter emerald green color from the beginning, and the leaves were thicker and glossy. The plant morphology was relatively strong, and the overall height was slightly higher than that of the control group. The growth rate was fast, and the time from sowing to germination was similar to that of the control group, about 3 days, but it was significantly faster in subsequent growth, and it took 28 days to grow to the measurable fresh weight stage. During the growth process, it can be observed that its root system is relatively developed, which can better absorb nutrients and water.

[0232] The leaves of the Chinese cabbage in test group B were dark green and full of vitality. The plants were tall and strong, with broad and thick leaves. It had the fastest growth rate, with a time of 2 days from sowing to germination, and only 25 days to grow to the measurable fresh weight stage. Its root system was extremely developed and widely distributed in the soil, which could fully utilize the nutrients and water in the soil, providing a guarantee for the rapid growth of the plant.

[0233] (2) Average fresh weight

[0234] After a one-month growth cycle, the fresh weight of the pakchoy in the control group, experimental group A and experimental group B was measured. The average fresh weight of the 10 pakchoy in the control group was 80g. Since no microwave chicken manure fertilizer was added, its growth mainly relied on conventional fertilizers, and the nutrient supply was relatively limited, resulting in slow plant growth and relatively low fresh weight.

[0235] The average fresh weight of 10 Chinese cabbages in test group A was 105g. After adding 10% microwave chicken manure fertilizer, the nutrients in the fertilizer were richer, providing more nutritional support for the growth of Chinese cabbage. Compared with the control group, the average fresh weight increased to a certain extent, indicating that an appropriate amount of microwave chicken manure fertilizer can promote the growth of Chinese cabbage and increase its fresh weight.

[0236] The average fresh weight of 10 Chinese cabbages in test group B was 120g. After adding 20% ​​microwave chicken manure fertilizer, the nutrient supply was more sufficient, making the Chinese cabbage grow rapidly, the plants strong, and the fresh weight was significantly higher than that of the control group and test group A. This shows that within a certain range, increasing the proportion of microwave chicken manure fertilizer can further improve the growth quality and fresh weight of Chinese cabbage.

[0237] According to the results of the above examples and control tests, accurate control of microwave treatment parameters (water content, power, time) is crucial for the chicken manure treatment effect. Excessive water content, improper microwave power or time setting will affect the effectiveness of the treatment and the quality of the final product. Therefore, in practical applications, the optimal parameter settings should be strictly followed to optimize the treatment effect and resource utilization.

[0238] Although the above embodiment describes the present invention in detail, it is only a part of the embodiments of the present invention, not all of the embodiments. People can also obtain other embodiments based on this embodiment without creativity, and these embodiments all fall within the protection scope of the present invention.
