Advantages of fermenting feeds using starter Jinbao starter ferments various straws, fertilizers, etc. I. Probiotics often used in the production of probiotic fermented feed There are many kinds of probiotics, and more than 40 species have been announced by the FDA and AAFCO. China's Ministry of Agriculture issued in December 2003 No. 318 "Category of Feed Additives Catalogue" in 15 species: Bacillus licheniformis, Bacillus subtilis, Bifidobacterium bifidum, Enterococcus faecalis, Enterococcus faecium, Enterococcus lactis, Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus plantarum, Lactobacillus plantarum, Pediococcus acidiformis, Pediococcus pentosaceus, Candida utilis, Saccharomyces cerevisiae, Pseudomonas palustris. The types of probiotics currently used in the market for feed fermentation are mainly lactic acid bacteria, bacillus, yeast and mold. Lactic acid bacteria are the earliest and most widely used probiotics. They are the generic name for bacteria that produce large amounts of lactic acid during the fermentation of available carbohydrates. Usually anaerobic or facultative anaerobic bacteria, acid-resistant, can still grow at a pH of 4.5 or less. Studies have found that metabolites and live bacilli have strong inhibitory effects on gram-positive and gram-negative bacteria. Bacteria effect, as the pH value decreases, the antibacterial effect gradually becomes stronger, living organisms and metabolites contain higher superoxide dismutase (SOD), which can enhance the animal's humoral and cellular immunity. Bacillus is a kind of aerobic bacteria that can produce spores, can tolerate high temperature, high pressure and acid and alkali, and has strong vitality. Bacillus can tolerate the destruction of stomach acid and bile salts and digestive juices in the upper digestive tract. After reaching the lower segment of the digestive tract, Bacillus grows and reproduces. Bacillus is aerobic and consumes large amounts of oxygen in the intestinal tract to maintain the anaerobic environment of the intestine. This promotes the growth of anaerobic probiotics such as lactic acid bacteria Bifidobacterium, inhibits the growth of aerobic pathogens, and maintains the balance of flora in the intestine of animals. Bacillus can produce vitamin B1, B2, B6 and other B vitamins, vitamin C, protease, amylase and fat and other enzymes and a variety of metabolites, play a role in promoting the degradation of digestion and absorption of feed and animal nutrition metabolism. Yeast is a kind of non-filamentary eukaryotic microorganisms. It generally refers to a variety of single-celled fungi that can ferment sugars. Yeast cells are rich in protein, B vitamins, fats, sugars, enzymes and other nutrients. A large number of applied research experiments have proved that yeast has a role in improving the animal's virulence, improving animal performance and reducing stress. The main types of feed yeast are brewer's yeast and Candida utilis. Beer yeast can be used to ferment bread, in addition to beer and other beverages. The bacteria has high vitamin and protein content and can be used as food, medicinal and feed yeast. Candida utilis can ferment glucose, sucrose, raffinose and assimilate nitrate. Candida utilis protein content and vitamin B content are higher than brewer's yeast. It can use urea and nitrate as nitrogen sources without any growth factor. Of particular importance is the use of five- and six-carbon sugars, as well as the production of protein for human and animal consumption such as sulfurous acid, wood hydrolysates and molasses in the paper industry. Common molds include Rhizopus, Aspergillus niger and Aspergillus oryzae. Molds can use cellulose and starch to break down. Second, the type of probiotic fermentation feed Probiotic fermentation can be divided into liquid fermentation feed and solid fermentation feed according to the moisture content. Liquid fermentation feeds are used in many countries abroad, and lactic acid bacteria and yeast fermentation naturally occurring in feeds are commonly used. In general, domestic use of probiotic fermentation agents or strains, the use of solid fermentation feed technology. (A) Probiotic liquid fermentation feed Abroad, in the production of probiotics liquid fermentation feeds are generally not added strains, naturally fermented, and it is the lactic acid bacteria that play a dominant role in the fermented liquid fermentation feed microbial community. Winsen proposed the liquid fermentation feed index was recognized by the majority of researchers: pH9log10CFU/mL, lactic acid content>150mmol/L, acetate content (b) Probiotics for solid fermentation feed The types of probiotic solid-state fermentation feeds can be roughly divided into: full-price probiotic fermentation feeds, probiotic fermentation concentrates, fermented soybean meal, yeast cultures, and other fermentation products. 1, full price probiotic fermentation feed The full-price probiotic fermented feed is prepared by adding probiotics and water to a nutritionally balanced whole antibiotic-free full-priced compound feed and mixing it with anaerobic or aerobic fermentation at a suitable temperature. This type of feed not only fully satisfies the nutritional needs of animals, but also increases the content of various digestive enzymes, organic acids, vitamins, peptides, small peptides, and amino acids, and is rich in a large number of probiotics. It has obvious biological effects such as promoting growth, preventing diseases, and has good control effect on intestinal diseases and can save production costs. 2, probiotic fermentation concentrate The probiotic fermentation concentrate is a non-full-priced feed produced by mixing a concentrated feed without an antibiotic with probiotics, water, and the like. Compared with the full-price probiotic fermented feed, the probiotic fermentation concentrate has only a small amount of energy feed in the production, has the same function as other functions, has the advantages of small volume and convenient transportation, and is the most promising product in the market. 3, probiotic fermented soybean meal Probiotic Fermented Soybean Meal is a high-grade feed protein rich in small peptides made from soybean meal and fermented by probiotics. Due to the deep research on the nutrition mechanism of small peptides, the excellent effect of the application of probiotic fermented soybean meal in feed, and the decrease in the price of global fish meal production, the probiotic fermented soybean meal has become a hot spot in the feed industry. The content of small and medium peptides and the elimination degree of anti-nutritional factors in probiotic fermented soybean meal are closely related to the microbial species and fermentation process used in the fermentation. In the production, a variety of probiotics are commonly used to promote enzymolysis, decomposition of antigens and anti-nutritional factors, Through a series of probiotics, the probiotics are digested in stages to make the protein fully degraded. The product is rich in various active peptides, probiotics, bioactive enzymes and so on. Probiotic Fermented Soybean meal has been mass-produced in many parts of the country and is used as a high-quality feed protein vegetable protein source in high-grade feeds. 4, yeast culture From the point of view of yeast culture products used at home and abroad, they are divided into two major categories: one is a yeast culture in which yeast living cells are the main functional part; the other is a large amount of yeast metabolites containing The main functional part of the product does not emphasize the role of living cells. The product consists mainly of yeast metabolites, yeast cells, and a medium that has been denatured after fermentation. Yeast cultures can significantly increase the production performance of ruminants. 5, other fermentation products In addition to the above mentioned probiotic fermentation feeds that have undergone large-scale industrial volume production, there are other unique fermentation products, such as: silage; cottonseed cakes (coriander cakes), rapeseed cakes (coriander cakes), and camellia cakes. The feed protein made by fermentation and detoxification; the fermented feed made from industrial wastes such as sugar beet residue, beer slag, bean dregs, citric acid residue, corn starch residue, and fruit residue, etc.; made of agricultural waste straw, etc. Fermentation feed etc. Jinbao starter ferments various straws, fertilizers, etc. Third, the effectiveness of probiotic fermentation feed (I) Reducing the amount of harmful microorganisms in feed Lactobacillus fermentation can reduce the pH of feed to less than 4.5, which can inhibit the growth of potential pathogens in feed and reduce the number of harmful microorganisms. Winsen et al. found that the use of L. plantarum in the first 2 hours of fermentation of pig feed Bacteria effect, and then showed a bactericidal effect. (B) Maintaining Animal Gastrointestinal Flora Balance The feed has a carrier effect on the probiotics adhering thereto, and the probiotics enter the animal body with the fermented feed pellets to fully exert the probiotic effect. Probiotics can adhere to the intestinal wall cells and act as a barrier, competitively inhibiting the rejection of pathogenic bacteria. A variety of probiotics inhibit the proliferation and growth of harmful bacteria in the gastrointestinal tract. Liu Jinping used a fermented feed to feed piglets. Compared with the control group, the number of lactic acid bacteria in the jejunum and caecum of the piglets increased by 9.65% and 18.11%, respectively; the number of jejunum and cecum in the test group decreased by 9.26% and 12.32%, respectively; and jejunal and cecal Salmonella were observed. The number decreased by 5.93% and 17.58% respectively. Gu Yan et al. reported that the lactobacillus used to feed the weaned piglets with fermented feed was significantly higher in the jejunum than in the control group (P<0.05). (three) enhance immunity Probiotics in the digestive tract are good immune activators that can stimulate the growth and development of intestinal immune organs, increase the level of animal antibodies and macrophage activity, enhance the body's humoral and cellular immune functions, and promptly kill the invading pathogens. Bacteria enhance the resistance of animals to a variety of diseases, significantly reducing the incidence and mortality rate. The golden pile reported that adding lactic acid bacteria fermented feed to the diet fed to pigs coincided with the occurrence of epidemic diarrhea during the trial. Eighteen pigs developed before and after the control group, and the treatment time was long (7 days); the incidence of pigs in the experimental group was 7 and the course of the disease Short (3d) shows that lactic acid bacteria fermented feed can significantly enhance the immune function of pigs and improve disease resistance. (D) Improve animal production performance After probiotic fermentation, the feed has a special flavor, good palatability, stimulates appetite, and increases feed intake; at the same time, proteases, lipases, and cellulases produced by probiotics can help animals digest and absorb, resulting in higher conversion utilization. , can improve animal production performance. 1, improve poultry production performance Zhu Liguo used a full-price solid-fermented diet for the performance test of ducks. The experimental composition had a living rate of 99.20%, which was 96.80% higher than that of the control group. When the same amount of feed was consumed, the average weight of the ducks in the experimental group was the same. It was 2863 g, an increase of 7.23% compared with 2670 g in the control group. The overall feed-to-meat ratio was 2.49:1, which was lower than the 2.67:1 of the control group. Zhang Hongjun et al used 2000 strains of egg-laying chickens to test the feeding of multiple strains of fermented feed. The egg ratio in the experimental group was significantly lower than that in the control group; the egg production rate in the experimental group was significantly higher than that in the control group; the egg weight in the experimental group was extremely high. In the control group, and the use of fermented feeds reduced feed costs. 2. Improve ruminant production performance Yan Changguo et al. fed Yanbian yellow cattle with fermented feed. The daily gains of the experimental and control groups were 0.98 kg and 0.77 kg, respectively. The difference was extremely significant (P 3, improve pig production performance Liu Jinping's study on piglets fed a fermented feed made from Lactobacillus plantarum A6 showed that the final weight of the experimental group was significantly higher than the control group by 13.85% (P (five) improve the environment Feeding animals with probiotic fermented feeds, probiotics can inhibit spoilage bacteria in the intestine, reduce the production of harmful substances such as ammonia, biogenic amines, and quinones, and produce amino oxidases and enzymes that decompose hydrogen sulfide, which can be used in bacilli. Material degradation, thereby reducing ammonia, hydrogen sulfide concentration and odor in livestock houses, reducing pollution and improving the environment. In the Demecková trial, the coliforms of feces fed liquid fermented sows were significantly lower than those of controls (P Fourth, summary It has been reported that probiotic fermented feed not only has the effect of probiotics, such as maintaining the balance of gastrointestinal flora of animals, raising the immune level, promoting animal growth and improving the environment, has no residue, no resistance and no toxicity Such advantages, and as a functional feed, it also has the advantages of smell, good palatability, animal preferences, simple and convenient feeding, saving time and effort, high digestibility, and stable efficacy. Probiotic fermentation feed technology integrates animal nutrition, feed science, microbiology and other discipline knowledge; combined with feed industry technology, fermentation engineering technology, enzyme engineering technology. Probiotic fermentation feed technology is an ecological environment-friendly feed production technology that meets the needs of healthy breeding in China. As people pay more attention to food safety, ecological security and environmental protection, as people's demand for pollution-free, health-care products of meat, eggs and milk increases, probiotic fermented feed will play an increasingly important role in animal ecological aquaculture production. The more important the role. V. Gold Baby - Feed Fermenting Expert Beijing Huaxia Kangyuan Technology Co., Ltd. is not a trade-oriented enterprise, not a sales-oriented enterprise.

Since the 1950s, the addition of antibiotics to animal diets has significantly promoted animal production and has made significant contributions to the development of intensive livestock husbandry. However, with the passage of time, the hazards of adding antibiotics to feeds have become increasingly apparent and have received widespread attention from the society. In 2004, the WTO, the UN Food and Agriculture Organisation (FAO) and the World Organisation for Animal Health (OIE) jointly held a symposium to discuss the use of non-human antibiotics and antibiotic resistance. Since January 2006, the EU has completely banned the addition of antibiotics to livestock and poultry feed. It is currently an internationally recognized food safety standard that no antibiotics can be added to pigs and other animals. People began to look for other alternatives and alternative technologies to ensure that the efficiency and effectiveness of livestock production are not affected. Probiotics Fermentation Feed Technology is a newly developed new feed technology with many advantages. Probiotics contain more active probiotic bacteria, various enzymes, metabolites at various levels, multivitamins, and protein breakdown products after probiotic fermentation. , active peptides, amino acids, bacteriostatic substances, immune enhancement factors, growth promoting factors, etc., play a role in promoting growth and maintaining the balance of flora in the intestine of animals; as no antibiotics and other drugs are added, antibiotic drug residues will not be caused. Bacterial fermentation feed technology is an ecologically healthy feed production technology. This article reviews the current research progress of probiotic fermentation feeds.
