In the past 20 years, people have gradually realized the potential harm of antibiotics to humans and animals. Therefore, in animal nutrition research and animal breeding, people have to spend a lot of effort to study antibiotic substitutes and their application and promotion. The Ministry of Agriculture Feed Engineering Research Center and Yan Ya Yuda Biotechnology Co., Ltd., through joint efforts, combined with traditional fermentation feed technology and traditional food fermentation anti-bacterial contamination experience, invented a removable membrane fermentation technology with respiratory membrane. The key innovation of this technology lies in the invention of a living respiratory device that can maintain the high activity and metabolism of beneficial microorganisms in the natural state—the respiratory membrane, which can make live bacteria (mainly lactobacillus and yeast) in nature Under conditions, high activity can be maintained for a long period of time. Cleverly solved the problem of heat dissipation, anaerobic control, and packaging, storage, transportation and stability of microbial solid-state fermentation.
The Role of High-Efficiency Respiratory Membrane Solid State Fermentation Core Technology in Antibiotic Problems High-Efficiency Respiratory Membrane Solid State Fermentation Production Technology uses a variety of light industrial by-products or chowder as a fermentation substrate. Raw materials do not need to be sterilized, and original microbial respiratory membranes and packaging are used. The post-fermentation mobile microbe anaerobic solid-state fermentation process produces low-cost, large-scale production of complex cultures containing beneficial microorganisms, and the number of live lactic acid bacteria per gram of finished fermentation material can reach 1 billion. Under the existing conditions of live pig feeding in China, adding 15% to 25% of fermented feed in compound feed can completely replace antibiotics. Under the condition of basically no increase in feed costs, pigs can be raised from 15 kg to the slaughter without antibiotics, and the quality of pork can be achieved. EU safety meat requirements.
Decomposition of some toxic and harmful substances by high-efficiency respiration membrane solid-state fermentation technology When raw materials containing natural harmful ingredients (such as gossypol and tannin) are used in feeds, if animals consume harmful ingredients for a long time, they will affect the growth of animals and human health. Due to the lack of protein resources in our country and the relative abundance of the resources of clams, the utilization rate is relatively low. Therefore, in animal husbandry production, people use various methods to produce detoxified cotton aphids and detoxicated ricinus, etc., to replace some of the pods and increase their productivity. Use in poultry diets. Through high-efficiency respiratory membrane solid-state fermentation technology, it can effectively degrade harmful substances contained in cotton aphid, which can be stored and fermented at room temperature. The degradation rate of toxic and harmful substances can reach 70% to 80%. The addition of 15% cottonseed meal to the fermented feed had no negative effects on the pigs or the finishing pigs.
The technology can block the pathogens through the feed to spread the production of fermented feed, most of the raw materials with a variety of microorganisms, including mold, bacteria-based. Although the raw materials of this technology are not sterilized and sterilized, high-efficiency respiration membrane solid-state fermentation is carried out under anaerobic conditions. A large number of tests have proved that the mold is completely killed during the fermentation process. For bacteria that can survive under anaerobic or facultative anaerobic conditions, such as E. coli and Salmonella in feedstuffs, the combined action of yeast, Lactobacillus, and Bacillus quickly consumes oxygen and forms a strong acidic environment (pH drops to 4.2~ 5.0) Under anaerobic and strong acidic conditions, the growth and reproduction of harmful bacteria is inhibited until they are killed, thereby blocking the pathogenic risk of the feed pathway pathogens. When the beneficial bacteria consumes oxygen, the carbon dioxide produced is discharged through the respiratory membrane to the fermentation bag, and outside air cannot enter the fermentation bag.
High-efficiency Respiratory Membrane Solid State Fermentation Technology to Solve the Shortage of Feed Raw Materials At present, the protein feed gap in China is nearly 30 million tons (calculated by soybean meal), and the energy feed supply is also insufficient, but China's distiller's grains, vinegar residue, fruit residue, bean dregs, corn syrup and other agricultural side The total annual output of light and industrial by-products reached 100 million tons, with nearly 10 million tons of cottonseed meal and rapeseed meal. The use of the former is less than 20%, and the latter is less than 70%. Therefore, the solid-state fermentation technology for respiratory membranes provides a suitable way to make full use of a large number of agricultural and sideline products, light industrial by-products, and to solve major issues such as human-animal crop production.
Fermentation feeds are produced through high-efficiency respiration membrane solid-state fermentation technology, mainly using corn pulp and chowder as protein raw materials, light industry by-products such as fruit residue and bean dregs as microbial growth and maintenance energy sources. With a high protein content of bean dregs, it can provide a nitrogen source for microbial growth and reproduction. Through efficient solid-state fermentation technology of respiratory membranes, the above raw materials are used to produce a fermented feed with a moisture content of about 30%. Such fermented feeds can be dried without drying, so that the above-mentioned raw materials can be efficiently used, and a large amount of energy consumption caused by the drying process can also be omitted.
High-efficiency respiration membrane solid-state fermentation technology effectively solves the light industrial by-products such as bean dregs, corn pulp, distiller's grains, vinegar residue, and pomace, and the temperature and humidity during the microbial fermentation process of high anti-nutrition factors such as cottonseed meal, rapeseed meal and other agricultural and sideline products. , pH control and other technical problems, making the microbial aerobic fermentation and anaerobic fermentation can be carried out in the same environment, inoculated with the combination of micro-organisms, can effectively inhibit and kill E. coli and Salmonella, while also promoting the rapid growth of lactic acid bacteria.
The annual output of pomace and bean dregs is more than several million tons. Using fruit residue or bean dregs as the nutrient source for microbial growth and reproduction, high-efficiency respiration membrane solid state fermentation technology is adopted to achieve efficient recycling of agricultural products such as pomace residue and bean dregs. At the same time, the feed production cost has been greatly reduced.
High-efficiency Respiratory Membrane Solid State Fermentation Technology is of Significant Importance to China's Feed Safety The implementation of the pig antibiotic-free breeding technology project by microbial fermentation without anti-feed has epoch-making significance. This technology will solve the problem of a total ban on the use of antibiotics in feed, and can increase the utilization rate of non-food feed resources such as distiller's grains, vinegar residue, fruit residue, cottonseed meal, rapeseed meal, etc., from 3% to 5%, and the amount added to animal feed can reach 20%. %～40%, simple production process, low cost, low investment, strong operability, convenient use of finished products, especially suitable for vast farms (households), building a conservation-minded society has great significance.
