First, the difference between micro storage and silage: Silage is a natural fermentation. In silage, it is fermented by microorganisms in the natural world. However, the silage fermentation requires strict time and environmental requirements, and the season is short. It is impossible for the microbes in the natural world to consciously and effectively control the quality of silage. People can only accept fate. Although silage is a favorite feed for livestock, it is still very limited due to these reasons. The term “micro-storage†refers to the abbreviation for the use of microbial strains for the fermentative storage of pasture and straw. (It is a term coined by the Urumqi Starfish Agricultural Science and Technology Application and Extension Service Station. It was also included in the “General Office of the State Council.†"China's Straw Breeding of Livestock to Back Abdomen Project Development Circular Notice" in 2000). Micro-storage fermentation is directional fermentation, that is, high efficiency and concentration of high-quality microbial strains are added to the micro-storage of pasture and straw, so that the fermented pasture or straw is in the dominant microbial population from the start of fermentation, and at the same time, the growth of microorganisms and Breeding creates an environment conducive to the rapid propagation of these beneficial microorganisms, thereby suppressing the activities of harmful microorganisms and stabilizing micro-storage. Second, microbiological microorganisms in feed Starfish "micro storage king" straw live fermentation of microbial strains are mainly the following: lactic acid bacteria, cellulolytic bacteria, propionic acid bacteria composed of bacteria. (1) Lactic Acid Bacteria: Lactic acid bacteria can ferment sugars to produce lactic acid, and lactic acid can be absorbed and used by livestock. As the silage raw material has a large amount of moisture, the silage materials generally need to be air-dried after harvest to reduce the moisture content to 45-55%. This is because the activities of aerobic fungi and spoilage bacteria are suppressed, but the activities of lactic acid bacteria are also suppressed. In the microflora on the surface of field grasses and straws, there are usually only small amounts of lactic acid bacteria. According to foreign experts' research on nine forage grasses, only two grasses had lactic acid bacteria exceeding 100/g. There are 6 kinds of pasture less than 10/g. Pasture can also be inoculated with lactic acid bacteria from agricultural implements, but this inoculation is not controlled. If a large quantity of lactic acid bacteria of good quality is inserted into the silage material at this time, the access and propagation of a large number of lactic acid bacteria can effectively inhibit the activities of harmful bacteria, thereby ensuring the stable quality of the micro-preservation feed. There are many kinds of lactic acid bacteria, and the lactic acid bacteria in the starfish “Micro Storage King†is Streptococcus lactis. Its wide adaptability range of 10-400C can reproduce and its viability is strong. High-quality lactic acid bacteria can produce a large amount of high-quality lactic acid. When lactic acid feeds micro-storage straw, the animals enter the animals along with the feed, help the animals digest and use concentrates, optimize the ratio of meat to meat, and increase milk production and meat production. (The experiment of beef cattle feeding in Yutian County, Hebei Province, organized by the Ministry of Agriculture in 1995 showed that: For a group of cows that eat micro-storage wheat straw, a weight gain of 0.319 kg per head/day is greater than for a group of cows that eat ordinary wheat straw. The weight gain of the wheat straw was 0.172 kg.In the dairy cow feeding trials, data from Wuhan and Taiyuan indicated that dairy cows' output of micro-seed milk increased by 15-20% per day. (2) Cellulose-decomposing bacteria: Enzymes produced by cell-decomposing bacteria can decompose cellulose and hemicellulose in grasses and straws, and can reduce the polysaccharides in cellulose and hemicellulose that are difficult to digest in domestic animals. Sugar and volatile fatty acids. Its monosaccharide can be used by lactic acid bacteria. Volatile fatty acids are the largest energy source for ruminant livestock. The combination of lactic acid bacteria and fiber-decomposing bacteria is a combination of symbiotic and complementary advantages. The fiber-decomposing bacteria used in the “micro-storage king†straw live fermentation strain of sea stars are spore-like and have very good gas properties, and their requirements for anaerobic conditions are not strict. Under appropriate conditions of temperature and humidity, the spores can be quickly opened, activated, propagated, and the remaining air in the cellar can be quickly consumed, creating more favorable conditions for the anaerobic activity and reproduction of lactic acid bacteria. The wheat straw microbiological test data in Xinjiang showed that when the fermentation started to the 7th day, the fiber-decomposing bacteria showed a logarithmic growth stage, proliferated 150 times, and then entered a stable growth stage, and on the 21st day, PH 4.8-5.0, 85% of the fiber-decomposing bacteria formed spores, but the total number of viable cells decreased by only 6.7% from the peak period. On the 28th day, when the pH was 4.2-4.6, all the cell-decomposing bacteria formed spores, and the total number of viable cells was still the same as that on the 21st day. . When ruminants feed on micro-feeds, the fiber-decomposing bacteria enter the rumen along with the micro-storage in the state of spores, which increases the number of fiber-decomposing bacteria in the rumen and improves the digestibility. This characteristic of cellulolytic bacteria also allows it to be stored for a long period of time in a dormant state. (3) propionic acid bacteria: propionic acid bacteria have a good anti-oxidation. It is active under both anaerobic and aerobic conditions and has a faculty. Propionic acid produced by propionic acid bacteria is an important glucose precursor in ruminants. Tests have shown that lactating cattle have increased their blood sugar content and alkali reserves after feeding microfeeds. This change in the cow's blood can improve its physiological state, so that the cow can produce calves normally. Calves are also less susceptible to indigestion.
