Application of microbial fermentation bed pig technology

With the increasing scale and intensification of pig farming, more and more people are optimistic about the prospects of the pig-breeding industry, but the current pig industry is facing three major problems: first, animal product safety; The main causes of these three problems are drug residues, energy shortage, disease control, environmental pollution and so onWant to solve this problem, you can try the microbial fermentation bed pig technology, the use of microbial fermentation technology to solve the current problems, the following small compilation on a simple introduction to you"p style"text-align: "center"," "img src""alt" "microbial fermentation bed pig farming technology application" title "first, microbial fermentation bed ecological pig farming technology overviewfermentation bed pig also known as livestock and poultry feces in the original degradation of healthy breeding, in foreign countries, also known as deep pad breeding or natural breeding Fermentation bed farming technology is based on the principle of ecology, the use of probiotic resources, biotechnology, fermentation technology, breeding technology and engineering technology in one of the modern integrated aquaculture technologyThe core of the technology is to fill in the pig shed deep organic pad material, so that pig feces in the organic mat material through microbial fermentation degradation, the full use of air convection and solar height angle principle, biological fermentation principle, greenhouse and gazebo effect principle, beneficial bacteria occupancy principle, to promote pig growth, improve the body's immunity, reduce disease at the same time, to achieve pig house (column, ring) free flushing, zero emissions, non-pollution harmony and unityThe key of this technology is to select and match the rice shell, wood chips, straw powder, rice bran and other organic matter according to local conditions, the use of beneficial bacteria after fermentation treatment into pig feeding material layer, pig manure-based nutrition, through carbon-nitrogen ratio, granularity, water regulation to promote the rapid reproduction of beneficial microorganisms, so that the growth and development of pathogenic microorganisms are inhibited, pig growth environment is significantly improved, feces and other excreta are constantly broken downthe technology has many advantages, namely, "three savings, two improvements, one growth, zero emissions" and so on, namely, water, materials, labor savings, improve resistance, improve the quality of meat, increase the efficiency of breeding, non-pollution, achieve zero emissions(1) completely solve the pollution of the environment of pig farming, solve the problem of fecal treatment, not only improve the environment of the pig farm, but also promote the constructionof new rural areas "style-style"line-height: 1.5;"""""""span-style"line-height:1.5;" "style"line-height: 1.5; Because the fermentation bed pig house adopts the full open form, the temperature and humidity of the pig house is suitable, the light is sufficient, the ventilation is good, which is conducive to the growth of the pigPig feces urine in the rapid decomposition of fermented bacteria, pig house will not smell and mosquito espertinIn addition, beneficial microorganisms can improve the resistance, disease, and stress resistanceof pigs; In the process of breeding antibacterial drugs, antibiotics do not use, can improve the quality of pork; After 3 years of use, the mat sishas is formed to form bio-organic fertilizer that can be used directly in fruit trees and crops, to achieve the effect of recycling and de-waste, andto improve labour productivity at thespan style "line-height: 1.5", "style"style"line-height: 1.5; Using fermentation bed pig farming technology, each person can raise 100 to 200 sows or fattening pigs 500 to 1,000 head, the amount of breeding greatly increased, because the technology does not need to wash the pig house and remove pig manure, labor productivity has been greatly improvedspan style"line-height: 1.5; Fermentation bed pig farming technology than traditional breeding technology to save water consumption of 75% to 90%, only in hydropower, veterinary drugs, feed and other aspects of savings, each pig can increase efficiency of 50 to 80 yuan.the technology of fermentation bed pig farming in Anhui Province has been tested and applied in the area since 2006In view of the natural conditions of high temperature and high humidity in the southern region of China, especially in Anhui Province, the main station of animal husbandry technology in Anhui Province has organized the research and application of the relevant institutions and promotion departments to carry out research on the technology of fermentation bed pig farmingThrough the pilot, the technology to "environmental protection, safety, efficiency" and other advantages gradually widely recognized, has been applied in all 16 cities, forming a good promotion atmosphere, and achieved good resultssecond, the promotion and application of microbial fermentation bed pig technology 1, the scope of application and design modeaccording to the fermentation bed to maintain permeability, rain,rain, waterproof immersion this characteristic, feidong county in the promotion and application according to the geographical environment and groundwater level of the choice of different design mode: in the south, close to the nest The farms in the lake basin, choose the above-ground trough model, promote the area of more than 1500m2, in the north, located in the Jianghuai watershed of the farm, promote the underground groove model, promote the area of more than 3000m2, in the north-south farm, the use of semi-underground groove mode, the promotion area of more than 600m22, different mode of design technical pointsis the above-ground slot modeOn the ground to build a mat tank, the bottom of the pad tank and the ground outside the pig house basically flat or slightly high, operating channels, hard platform to cushion 50 to 100 cm high, conservation pigs, fattening pigs are 50 to 80, 100 cm, using the outer wall of the pig house, hard platform side of the construction of long grooves, and with iron fences to separate, to avoid pigs string each otherThe second is the underground slot modeUnder the surface of the construction of mat inge, groove depth of 60 to 100 cm, conservation pigs, fattening pigs are about 60, 100 cm, respectivelyIf the new pig farm, the underground long groove slot is excavated at one time, and then separated by iron fence into multiple circles, if the old pighouse transformation, you can dig the pit in the original circle barThe third is the semi-underground groove modeOn the ground and underground each built 1/2 cushion tank, operating channels, hard platform with excavation of the underground part of the soil backfillingThe grooves of the conservation pigs and the fattening pigs are about 60 and 100 cm respectively, and the construction and separation mode of the long grooves are the same as the slots on the ground3, the composition of the fermentation material and theof bed maintenance in order to make the fermentation bed performance is good, should be scientifically selected matmaterialsPractice shows that the fermentation material is better in terms of materials with high carbon supply strength, balanced and long-lasting carbon supply capacity, permeability and good adsorption, in order to improve the carbon-nitrogen ratio and ensure that the overall carbon-nitrogen ratio of raw materials or raw material combinations of pig feeds in fermentation beds exceeds 25:1 The ratio of cushionmaterial should be based on the principle of local conditions, according to the cost of obtaining raw materials, difficult to adjust in a timely manner Taking the ecological pig farm in The East Tushan as an example, a new ground trough pattern of 300 m2 sawdust and corn straw was newly designed and the underground tank pattern of 300 m2 sawdust and rice shell was designed to be modified at the foot of the higher earth Specific formula: sawdust 60%, corn straw / rice shell 35%, deep soil 5%; accessories: coarse salt 0.3%, rice bran 2.5 kg /m3; 2 ways have advantages and disadvantages, sawdust and corn straw as a combination of feed materials, because the corn straw breathability is better, fermentation bed emission temperature is faster, so suitable for summer heat protection cooling, but also to save hard platform However, because the corn straw is relatively loose, long-term arch pressure, the bed body dropped faster, so timely turn over the bed and add sawdust Sawdust and rice shell as a combination of feed materials, because of the poor breathability of rice shell, fermentation bed emission temperature is slow, so suitable for winter insulation However, to maintain ventilation and ventilation, timely grasp of the changes in temperature and humidity, strengthen the management of manure, adjust the feeding density The maintenance of fermentation bed is to maintain the proper permeability of the mat material for a long time, can often turn the mat material, turn the depth of conservation pigs, breeding pigs are 15 to 20, 25 to 35 cm, respectively In order to allow the microorganisms in the mat to reproduce normally, the moisture content should usually be maintained at 38% to 45% Therefore, to constantly check the content of the moisture content of fermented mattress material, when the moisture of the mat is reduced, the moisture content of the mat should be increased by the humidification spray, so as to prevent the reproduction of microorganisms Because the digestion and decomposition of fecal urine will lose the pad material, so in order to make the fermentation bed stable performance, when its mat material is reduced by 10%, to be replenished in time, and the new material and fermentation bed mat solder evenly mixed, adjust the water the third, common problems and solutions 1, epidemic prevention and treatment problems normal immune procedures can not be reduced, especially large-scale pig farms are particularly important, but the amount of antibiotics and other drugs can be gradually reduced, the amount of reduction can generally reach more than 50% Pigs with severe infection or typical disease characteristics immediately isolated observation, treatment or elimination, and effectively do a good job of harmless treatment of dead pigs 2, disinfection problems due to the presence of fermented bacteria in the mat material, once the disease or epidemic, must be disinfected And the normal disinfection will hardly affect the work of the fermentation bed, disinfection time after a period of time do not turn over the bed 3, temperature control problems the normal temperature of the fermentation bed treatment: the factors affecting the temperature of the fermentation bed are mainly moisture and permeability, sometimes as a single factor, sometimes as two factors at the same time If the moisture is too high and/or the pad is too loose, fermentation strength will increase, the temperature will be too high, the commonly used treatment method is to slightly compact the mat, or supplement some of the dry material will be slightly compacted the pad; Usually can be properly replenished by the water, enhance the permeability of the pad material to solve, if the water is too high or too low will also lead to the fermentation bed temperature is too low, the solution is to adjust the water well, if the mat permeability is too low, the temperature of the fermentation bed is also low, then it is necessary to use loose mats to increase the fermentation strength of the mat, thereby improving the temperature of the fermentation bed summer heat-proof cooling measures: First, to improve the insulation capacity of the outer protective structure of the pig house, and second, to adjust the thickness and humidity of the pad, hot summer high temperature and humidity, ventilation and cooling can not play a significant role (the temperature inside and outside the pig house will be as high as 40 degrees C), if the pad material spent Thick, the heat of the two overlay, the temperature is higher, so to reduce the thickness of the mat to about 45 cm; 4, humidity control problems the cutting material fermentation process, if not heated, because the moisture is too high or too low, can properly adjust the moisture, add the feed raw materials or add water If the humidity of the fermentation bed is too large, can be appropriately flipping the mat material (or supplementing the new pad material) to solve, when the humidity of the pig house can be properly through the negative pressure pumping air to solve or clear too wet mat dry ingested into the bed; 5, summer and winter mat sage maintenance summer conservation to try to control the moisture of the mat, reduce fermentation strength; Winter conservation is routine except for special requirements in the conservation column The winter conservation of the conservation bar should also pay attention to control the water of the mat, because the pig manure urine is less, the fermentation strength of the mat is relatively low, such as too much water will lead to large heat loss, but also will lead to increased air humidity in the nursery, resulting in stress Therefore, it is best to use pine, birch or oily sawdust when using sawdust, as such sawdust is not used poorly And the water table is high, the fermentation bed fermentation pool must not dig down, once dug down, summer may lead to the bottom of the fermentation bed seepage, resulting in the failure of the fermentation bed fourth, application prospect microbial fermentation bed ecological culture technology is a technological innovation in the aquaculture industry, is a complex system engineering, this technology can save resources, improve the environment, improve the quality of livestock products, in line with the needs of the low-carbon development of the times In addition, the fermentation mattress material variable waste for treasure, recycling, the production of organic rice, organic fruit forest Can also be combined with the new rural "one pool three changes" (biogas digesters and change sourcing, toilet, change of circles), strengthen three-dimensional ecological aquaculture, promote the harmony of breeding, environment, resources and human harmony.
