Description

Technical Field

[0001] The invention relates to the technical field of ecological agricultural breeding, and in particular to an ecological cycle pig farm and a pig breeding method. Background Art

[0002] China is the world's largest livestock and poultry breeding country. With the increase of China's population and the improvement of people's living standards, the annual per capita consumption of pork and the total amount of pigs will surely increase. With the great improvement of living standards, people's demand for pork is increasing day by day, and the requirements for meat quality are getting higher and higher.

[0003] At present, imported farmed pigs are widely raised due to their short breeding period and high meat output, which has squeezed the demand for local pigs. Local pigs are being marginalized, and the risks of pig farming are getting greater and greater for pig farmers. The investment costs of feed and breeding facilities are getting higher and higher, resulting in a decline in pig farming efficiency, and the outbreak of large-scale epidemics is likely to result in a total loss of money. At present, my country's breeding industry is facing three major problems: quality and safety, efficiency improvement, and environmental governance, or the drug residues, energy lack, feed shortages, environmental pollution, etc., which are manifested by them. These factors have become bottlenecks restricting the further development of my country's breeding industry. Therefore, an ecological cycle pig farm and pig farming method are urgently needed to solve the above problems. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the shortcomings of the prior art, the present invention provides an ecological cycle pig farm and a pig farming method, which have the advantages of low-cost ecological farming, etc., and solve the problem that the investment cost of farmers' breeding facilities is getting higher and higher, resulting in a decline in pig farming efficiency, and the outbreak of large-scale epidemics is likely to result in a total loss of money.

[0006] (II) Technical solution

[0007] The technical solution of the present invention to solve the above technical problems is as follows: an ecological cycle pig farm, characterized in that it includes the following steps:

[0008] Step 1: Field design: heighten and reinforce the ridge of one mu of land to make the ridge height 70-80cm, remove weeds, stubble and stones in the field to ensure the field is clean, and dig drainage ditches at the ridge;

[0009] Step 2: Build a detachable pig shed, set partitions in the pig shed, plan three pig houses through the partitions, the ground of the pig house does not need to be hardened, the pig house is equipped with a drinking water pipe and a pig trough, and select domestic native pig breeds for breeding;

[0010] Step three: Build a detachable vegetable shed, set up a fence outside the vegetable shed, the fence is surrounded by a rectangle, and plant pasture in the open space between the fence and the ridge. A protective cover is installed on the inner top wall of the vegetable shed by bolts, and the bottom of the protective cover is inserted into the soil. The outside of the protective cover is rotatably connected to a protective door, and pea pods are planted in the protective cover to make them grow along the shed.

[0011] The beneficial effects of the present invention are:

[0012] This ecological cycle pig farm and pig farming method can harvest three kinds of benefits, pork, mushrooms and pea pods, and the breeding cost is low. The local pigs raised have high physical fitness, which reduces the possibility of disease and reduces risks. The meat is delicious and healthy, has high economic value, and is easy to promote.

[0013] It should be noted that by utilizing pig manure to grow mushrooms and other fungal crops, the ecological pressure is reduced and economic benefits are increased. By growing forage grass, feed costs are reduced. Setting up detachable pig greenhouses and vegetable sheds can be reused at low cost, which reduces the breeding risks for farmers and has the advantages of low-cost ecological breeding of native pigs.

[0014] Based on the above technical solution, the present invention can also be improved as follows.

[0015] Furthermore, the soil between the fence and the ridge is planted with grass, and the grass planting area is C-shaped. Grass is a good feed for pigs and needs to be used in combination with concentrated feed to ensure that the native pigs obtain comprehensive nutrition.

[0016] Furthermore, a clamping block is fixedly connected to the protective door, a clamping slot is provided inside the protective cover, the clamping block is inserted into the clamping slot, a threaded groove extending to the inside of the clamping block is provided inside the protective cover, and a bolt is connected to the internal thread of the threaded groove.

[0017] Furthermore, under the vegetable shed is an activity area for native pigs, and the urine and feces produced by the native pigs will seep into the soil, thereby providing nutrients to the grass and pea pods.

[0018] Furthermore, the pig house is a resting area for native pigs. Urine and feces produced by the native pigs are piled in the pig house. Hay and soil are added to cover the ground of the pig house every ten days. The native pigs are driven out and the pig house is replaced every two months. The three pig houses are used in turn.

[0019] Further, pile up the pig manure in the pig house and make sure no chemical additives or drugs are added. Let the pig manure ferment naturally for a period of time, which helps to decompose substances and reduce pathogens. Mix the pig manure with other materials such as sawdust, straw or corn stalks to increase air permeability and structural stability. The ratio of pig manure to other materials is 1:1.

[0020] Furthermore, the pH value required for mushroom growth is usually between 6.5 and 7.5. If the pH value of pig manure is not within this range, it needs to be adjusted. The mixed culture medium should be sterilized at high temperature to kill possible pathogens and pests. Steam sterilization or hot air sterilization can be used.

[0021] Furthermore, after the culture medium is cooled, the mushroom spores or mycelium are inoculated into the culture medium. The suitable temperature for mushroom growth is usually between 15-25°C, and the humidity needs to be maintained at 85%-95%. When the mushrooms grow to an appropriate size and the caps are fully expanded, they can be harvested. After the mushrooms are harvested, the culture medium may still contain nutrients and can be used for mushroom cultivation in the next pig house. By cleaning the culture medium in the pig house and moving it to other pig houses, the pig house can become a new rest area for native pigs.

[0022] Furthermore, the number of native pigs raised in the pig house does not exceed eight, and the pig shed is arranged roughly in an east-west direction, so that the pig shed has at least 2 hours of sunlight exposure time in winter.

[0023] The beneficial effect of adopting the above further scheme is to increase the light exposure time of native pigs in winter and ensure the physical fitness of native pigs. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In the embodiment, Figure 1-3 Provided is an ecological cycle pig farm and a pig farming method. The present invention includes an ecological cycle pig farm, which is characterized by comprising the following steps:

[0030] Step 1: Field design: raise and reinforce the ridges of one acre of land to a height of 70-80cm, remove weeds, stubble and stones from the fields, ensure the fields are clean, and dig drainage ditches at the ridges;

[0031] Step 2: Build a detachable pig shed 1, set partitions in the pig shed 1, plan three pig houses through the partitions, the ground of the pig house does not need to be hardened, and the pig house is equipped with a drinking water pipe and a pig trough, and select domestic native pig breeds for breeding;

[0032] Step three: Build a detachable vegetable shed 2, set a fence 3 on the outside of the vegetable shed, the fence 3 is surrounded by a rectangle, plant pasture in the open space between the fence 3 and the ridge, and install a protective cover 4 on the inner top wall of the vegetable shed 2 by bolts. The bottom of the protective cover 4 is inserted into the soil, and the outside of the protective cover 4 is rotatably connected to a protective door 5. Plant pea pods in the protective cover 4 so that they grow along the shed.

[0033] The number of native pigs raised in the pig house does not exceed eight. The pig shed 1 is roughly arranged along the east-west direction, so that the pig shed 1 has at least 2 hours of sunlight exposure time in winter.

[0034] Forage grass is planted in the soil between the fence 3 and the ridge. The planting area of ​​the forage grass is C-shaped. Forage grass species are selected: Forage grass varieties with high nutritional value and good palatability are selected, such as ryegrass, chicory, grain amaranth, etc. These forage grasses are rich in protein and vitamins. Forage grass is a good feed for pigs. At the same time, it needs to be used in combination with concentrated feed to ensure that native pigs get comprehensive nutrition.

[0035] It should be noted that the harvesting time should be arranged reasonably and excessive mowing should be avoided so as not to affect the regeneration ability of the grass. The amount of grass fed should be reasonably controlled according to the growth stage and weight of the pigs to avoid overfeeding. The harvested grass needs to be properly stored to avoid mold and deterioration. Attention should be paid to the moisture management of the grass to ensure that the pigs consume an appropriate amount of water.

[0036] A card block is fixedly connected to the protective door 5, a card slot is provided inside the protective cover 4, the card block is inserted into the card slot, a threaded groove extending to the inside of the card block is provided inside the protective cover 4, and a bolt is connected to the internal thread of the threaded groove. The protective door 5 is opened by removing the bolt, so that the pea pods in the protective cover 4 can be harvested.

[0037] The pig house is a resting area for native pigs. The urine and feces produced by the native pigs are piled in the pig house. Hay and soil are added to cover the floor of the pig house every ten days. The native pigs are driven out and the pig house is changed every two months. The three pig houses are used in rotation.

[0038] Under the vegetable shed 2 is the activity area for native pigs. The urine and feces produced by the native pigs will seep into the soil, thus providing nutrients to the grass and pea pods. Since the urine and feces will seep into the soil, after the fermentation bedding is placed, most of the feces will be degraded into bacterial protein under the fermentation action of microorganisms, and the water in the urine will be directly evaporated into water vapor and dissipated. There is no problem of cleaning feces and urine, which reduces labor intensity, improves work efficiency, and reduces the pressure on the ecological environment.

[0039] Pea pod varieties with strong disease resistance, strong branching ability and strong frost resistance are selected, such as white flower peas, medium pea No. 4, etc. According to the region and climatic conditions, March-April in spring or August-September in autumn are suitable for sowing. Protective covers 4 are set to prevent pea pods from lodging and at the same time, prevent native pigs from trampling and gnawing to cause withering.

[0040] Pile up the pig manure in the pig house and make sure no chemical additives or drugs are added. Let the pig manure ferment naturally for a period of time, which helps to decompose substances and reduce pathogens. Mix the pig manure with other materials, such as sawdust, straw or corn stalks, to increase air permeability and structural stability. The ratio of pig manure to other materials is 1:1. The pH value required for mushroom growth is usually between 6.5 and 7.5. If the pH value of pig manure is not within this range, it needs to be adjusted. The mixed culture medium is sterilized at high temperature to kill possible pathogens and pests. Steam sterilization or hot air sterilization can be used. After the culture medium is cooled, the spores or mycelium of the mushrooms are inoculated into the culture medium. The variety of mushrooms is straw mushroom. The suitable temperature for mushroom growth is usually between 15-25℃, and the humidity needs to be maintained at 85%-95%. When the mushrooms grow to the appropriate size and the cap is fully expanded, they can be harvested. After the mushrooms are harvested, the culture medium may still contain nutrients and can continue to be used for mushroom cultivation in the next pig house. By cleaning the culture medium in the pig house to other pig houses, the pig house becomes a new rest area for native pigs.

[0041] After one acre of land has been used for 2 to 3 years, the organic matter in the land reaches 60cm deep and the land needs to be replaced, otherwise there will be ecological pressure. The soil quality of the land has been improved and the soil is fertile, making it suitable for growing rice and other products.

[0042] By providing local pigs with sufficient space and materials, meeting their needs for play, ensuring their physical fitness, reducing the possibility of disease, and improving their overall health level, although the local pigs raised in ecological farming produce less meat, the meat is delicious and healthy, reflecting high-value agricultural products. Although the harvest cycle is longer than that of imported pigs, the price is better than that of imported pigs, thus ensuring that farmers' income remains unchanged and facilitating promotion.

[0043] It should be noted that three kinds of income can be harvested from one acre of land, pork, mushrooms and pea pods. By utilizing pig manure to grow mushrooms and other fungal crops, the ecological pressure is reduced and economic benefits are increased. By growing forage grass to reduce feed costs, and setting up detachable pig sheds and vegetable sheds, the construction of ecological pig farms can achieve circular breeding, clean production, zero emissions, is environmentally friendly, low-cost, and reduces farmers' breeding risks.

[0044] The breeds of native pigs include Jinhua pigs, Rongchang pigs and Chenghua pigs. These breeds have not only adapted to the local environment, but also been loved and protected by people because of their unique genetic characteristics and meat flavor. Many local governments and research institutions are committed to protecting and improving these precious genetic resources, so this breeding method is proposed to protect local native pigs and promote farmers to raise native pigs to obtain economic benefits.

[0045] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
