Example Embodiment

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0020] A preparation process of a microbial fermentation mat for pig breeding, the process includes the following steps:
[0021] A. Litter: layer the chaff, sawdust and corn stalks in the fence;
[0022] B. Add bacteria: Spray the No. Ⅱ aqueous solution of organic beauty ecological bacteria agent containing yeast, photosynthetic bacteria, lactic acid bacteria and fecal cocci on the litter by spraying;
[0023] C. Stir evenly: Turn the litter manually to make the material of each layer evenly distributed and ferment naturally.
[0024] D. Fermentation and decomposition of feces and urine: adding microbial compound preparations and azotrophic bacteria to degrade pig feces and urine, 1 year of bacterial bed utilization time, degradation of feces and urine, deodorization, rich organic matter in fertilizers, and heavy metals not exceeding the standard;
[0025] E. Feeding pigs: drive the nursery pigs or reared pigs into the pens, and combine the feeding with probiotics and spraying in the drinking water environment;
[0026] F. Maintenance and management of mattress: 1), the area of ​​each column is 150m 2 Right and left are appropriate to facilitate daily maintenance of the litter; 2) The area of ​​the litter is about 70% of the area of ​​the pen, and the remaining area should be hardened to become a hard floor platform for pigs to eat or a resting place with high temperature/constant temperature in summer 3). The height of litter should be 40-50cm for nursery pigs and 55-60cm for rearing pigs. Generally, it can be low in southern areas, high in northern areas, low in summer, and high in winter; 4), rearing The density of pig breeding is about 10% compared with the conventional breeding method (decrease/increase), so that the bedding can fully decompose feces and excrement in time and maintain a healthy breeding environment; 5) The design of the import and export of bedding should meet the requirements of feeding and cleaning. It is convenient to operate when the tank (that is, the litter needs to be removed from the litter tank when it is used for a certain period of time); 6) The humidification device should ensure that it can be shared when the litter is maintained and added; 7) The ventilation facilities are complete, and the southern summer Consider the humidification curtain when it is warm, and turn on the exhaust fan regularly in winter to avoid the humidity of the pig house from greater than 65%;
[0027] G. The pig will be slaughtered.
[0028] The bed is set up to establish the dominant probiotic flora inside and outside the pigs and the dominant probiotic flora in the living environment of the pigs, and it can double the invasion of pathogenic microorganisms from the inside and outside of the pigs, and the pig raising process is pollution-free and zero. Emissions, pigs are healthy, less sick, grow faster, save feed, save water, save energy, and have high quality pork. A piglet can earn about 100 yuan more (direct benefit). A breeding sow produces two more piglets per year. The raising rate of piglets in nursery houses is increased by about 10%, and the rate of raising piglets for fattening is increased by about 2-3%.
[0029] The litter in step A consists of four layers, and the bottom layer is a whole bundle of corn stalks with a thickness of 20cm; the penultimate layer is a chaff layer with a thickness of 15cm; the penultimate layer is a mixture of sawdust and rice husk Laying + spraying propagation bacteria solution + all sprinkling corn flour + 75kg corn flour mixed, and the thickness is 15cm; the top layer is sawdust + rice husk mixed laying + spraying propagation bacteria solution + all sprinkling corn flour + 3.3kg microorganism It is made from a mixture of species and has a thickness of 15cm.
[0030] The temperature of the penultimate layer is controlled at 40-55°C, the temperature of the penultimate layer is controlled at 45-55°C, and urine and feces decompose in this layer; the temperature of the uppermost layer is controlled at 22°C.
[0031] Step D also includes three steps, and the three steps are respectively killing parasite eggs, killing parasite eggs and establishing a dominant flora of probiotics. At the same time, the establishment of dominant flora includes the following steps 1) , Add Bacillus natto species, yeast species, photosynthetic species, lactic acid species and fecal cocci species; 2), the first turn; 3), the litter is used for a period of time after the second turn to complete the entire The fermentation process, and the number of viable bacteria after fermentation is greater than 10 8 Pieces/g.
[0032] In step G, press 150m 2 Take a bed as an example: 4t of sawdust, 12t of rice husk, 3t of corn stalks, 10kg of microbial stock (the ratio of propagating fungus to water is 1:15), and the construction of pig houses has two modes: single row and double row At the same time, the underground tank mode is the most suitable for breeding in the north.
[0033] When in use, a bedding is set to reduce the odor in the house (the compound microbial flora of excrement and bedding has a biochemical reaction to produce CO 2 (And water, etc.), environmental spraying to reduce odor in the house (aerosol sprays beneficial bacteria in the house to decompose the odor in the house and reduce environmental pollution), biological deodorization (functional bacteria can absorb and dissolve the fecal protein in the litter Substances are treated as their own nutrients, and through the fermentation process, they are transformed into bacterial proteins and oligosaccharides, which fundamentally eliminate the odor, which is the main deodorizing degradation reaction), and improve the immunity of pigs (replenish trace elements and cellulose) Decompose enzymes), reduce pig diseases (improve air quality, reduce respiratory diseases, reduce stress, and basically eliminate piglet diarrhea), produce non-resistant pork (do not use antibiotics, and ferment complete feed through microorganisms) The fed pigs have even distribution of intermuscular fat, delicious meat, prolonged anti-oxidation time, strong water and fat locking of the finished product, high ketone body meat production rate, low cholesterol content, sweet taste and rich nutrition), zero discharge of feces (every pig Daily excretion of feces and urine is directly degraded and utilized by the azotrophic flora on the bed, without special treatment), improving economic benefits (improving digestion, saving feed, saving water and electricity energy input, saving investment in plant construction, and good uniformity of the whole group , Zero-emission, labor-saving, reducing diseases, saving traditional Chinese medicine), and can also reduce the meat-to-feed ratio (pigs are exposed to probiotics for a long time, improve the absorption rate of feed nutrients, reduce nutrient waste, and at the same time, by turning over the fungus bed The produced small-molecule bacterial protein and free amino acids/trace elements replace 5-10% of feed, reducing the meat-to-feed ratio on both sides) and reducing pollution (the use of microbial fermentation bed natural pig raising technology can improve the utilization of feed nutrients, Reduce the loss caused by nutrient discharge and environmental pollution) and increase the total profit (by saving feed, veterinary drugs, labor, electricity, water and sewage treatment costs, the overall farming profit can be improved).
[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. And variations, the scope of the present invention is defined by the appended claims and their equivalents.
