As people's living standards rising, consumers are increasingly demanding high meat products. Market supply relationship has gone from model to meet the health-and flavor-type transition. Especially after China's accession to WTO, the domestic consumption of the EU and other WTO look forward line, drug residues, antibiotics overweight has become the most concern to consumer groups, EM bacteria with its natural, non-toxic, no side effects, no residue, safety reliable, no pollution concerns superiority by the world, in recent years, with the rapid development of animal husbandry, EM bacteria in animal husbandry applications are increasingly widespread. A, EM bacteria concept: EM bacteria are beneficial microflora (Effective Microbes) in abbreviation, by the University of the Ryukyus in Japan developed by Professor Teruo Higa. It is composed of photosynthetic bacteria, lactic acid bacteria, yeast, actinomycetes, filamentous fungi and other fermented microbial cultures made multifunctional complex microbial flora. According to micro-ecological principles, by adjusting the intestinal microflora relationship between the advantages and disadvantages, to restore and maintain the ecological balance of microorganisms. Metabolism of a variety of enzymes, vitamins, amino acids and other substances, so as to improve animal growth rate and disease prevention purposes. Two, EM bacteria use: EM bacteria on poultry rearing methods are mainly three kinds of use. 1 EM fungi is 0.2% according to the amount of feed in the feed evenly sprayed directly on the keepers. 2 is diluted with 0.1% of EM fungi drinking water. 3 is diluted with 5% of EM fungi spray barns, improve the breeding environment. Three, EM role of bacteria and principles: 1. Prevent piglet intestinal diseases, and promote growth. Early weaned pigs due to inadequate development of the gastrointestinal tract, it is difficult to adapt after weaning, including the environment, feed and psychological changes that lead to gastrointestinal microbial flora in the original stable balance between being broken, causing severe diarrhea in piglets, increased mortality . It is the most common and most difficult to control piglets one of the diseases. In good insulation, ventilation, and epidemic prevention work, in the diet appropriate to add EM bacteria, improve piglet body's resistance is very important. EM bacteria into the digestive tract, the rapid proliferation, consume a lot of oxygen in the intestine, so that pathogenic aerobic and facultative bacteria dropped substantially, effective control of intestinal microbial flora, maintain intestinal flora balance, a lot of produce lactic acid bacteria, reduce intestinal PH value, effectively control E. coli and salmonella, which is conducive to the growth of piglets. (2) provide nutrition, disease prevention and treatment. Many cell itself contains a lot of nutrients, these microbes are added to the feed, can be used as nutrient uptake by animals use to promote animal growth, enhance physical fitness, improve resistance to disease. Some microorganisms in the fermentation or metabolic process produces growth hormone and other physiologically active substances, helps food digestion and nutrient absorption, promote metabolism; leavened by increasing the activity of certain enzymes or decrease certain to change harmful microbial metabolism, to the detriment of their growth; through increased antibody levels or increasing macrophage activity, enhancing the ability to stimulate the immune system. Some microbes can produce pharmacologically active substance, directly regulates the microbial flora, inhibit pathogens, control the occurrence of disease. These microorganisms are beneficial bacteria, they have poultry intestinal bacteria together to form a strong dominant species proliferate; through a competitive mechanism by which suppressed the proliferation of harmful bacteria. 3 to improve feed conversion ratio. Many microorganisms produce amylase, lipase and protease enzymes to digest through glycolysis starch, crude protein and other complex organic molecules that are degraded to some extent by the digestible monosaccharides, disaccharides and amino acids and other small molecules material is conducive to protein, fat, sugar metabolism and absorption; due to intestinal acidification favor iron, calcium and vitamin D absorption; Further, since the feeding livestock with EM fungi in vivo micro-ecological balance can vary, different functional microbial growth and metabolism in the body, can significantly enhance animal feed vivo absorption of various nutrients, thus improving feed conversion rate. 4. Improve meat color, as health food. EM fungi are rich in a lot of lactic acid bacteria, yeast, Bacillus, the genus Bifidobacterium other, mutual collaboration between them, to maintain a dynamic equilibrium. Into the animal body, can produce a variety of in vivo digestive enzymes and vitamins, relying on many of these fermentation activity of product synthesis of biologically active substances, and vitamins involved in energy metabolism, thereby promoting the body's digestion and absorption, improve the feed energy, protein, amino acids of utilization, enhanced nutrient metabolism in animals. Long-term use, good metabolism, digestion using high; meat quality, the structure has changed, reduced cholesterol meat, amino acids, trace elements content increased, decreased fat content, fresh meat, meat has been significantly improved. 5. Degradation of ammonia, improve breeding environment. EM fungi contain a lot of cellulose decomposing bacteria, hemicellulose decomposing bacteria, nitrogen-fixing bacteria, lactic acid bacteria, these microorganisms and animal intestinal beneficial bacteria within the synergies that can effectively enhance the activities of intestinal function, thereby improving the utilization of protein. Meanwhile, EM and intestinal beneficial bacteria proliferate originally bound to inhibit the activity of E. coli, thus reducing the protein to the conversion of ammonia and amines, the intestines and decrease the concentration of ammonia in the blood, reducing the amount of ammonia excreted, the stool becomes dry, does not stink, reduce ammonia nitrogen content, can reduce or even eliminate the generation of mosquitoes, thereby reducing the transmission of the disease in the media. Use of agricultural Beverly EM EM liquid bacteria homemade cost savings nearly 8-15 times!

According preconceived theory, through first-bacteria occupy sexual control, reduce or prevent pathogens settlement. EM bacteria effect of chicks young animals, and can help them to establish as soon as possible the normal intestinal microbial flora. (2) prohibits antibiotics, bactericidal drugs, disinfectants used simultaneously, otherwise they will kill or inhibit them viable, weakening or loss of the role of EM fungi. 3. EM bacteria prevention is better than treatment, the role play is slow, it should be a long continuous feeding, in order to achieve the desired results. 4 Note viability and quantity, EM bacteria must contain a certain amount of viable cells, generally require 300 million per ml have about viable body and a stronger vitality. 5 To pay attention to the preservation of EM fungi, its shelf life of six months, with preparations to save time, gradually reduce the number of viable cells, and its role has become increasingly smaller. 6.EM bacteria generally require stored in a cool dark place after each use be sure to tighten the cap, sealed. Current production of green and strengthen environmental protection to become the focus of attention, animal husbandry is human survival and development of basic industries, EM bacteria emergence and development of high-tech industries conform to the current focus on the environment and the mainstream, a good solution the current production and application problems, it is in the application of livestock will become increasingly widespread, development prospects
