Rumen microatic state balance and disorders – Dairy Forum – China Animal Husbandry Website – A useful animal husbandry website

There is a relationship between the various groups of microorganisms in the raft, and there is a relationship between interconnection and constraints between the host, thereby forming a micro-generating balance. If there is an out of control in the microforge system, the balance is destroyed, causing micro-state disorders, resulting in a healthy or digestive disease, and even affecting the health of the entire body.
1. The relationship between rumen microorganisms and hosts is extremely unique to digestion process, mainly manifesting most of the substances in the feed to be affected by microbicase in the rumen in the raft. Rumen microorganisms play an extremely important role in ruminant nutritional metabolism. There is a high anaerobic environment in the rumen, the temperature of 38 to 40 ° C, the animal-induced food is supplied to the nutrients required for the microorganism, while the tumor-rhythm-rhythmic exercise will mix the food and microorganisms. This forms a place where microbial life activities are extremely ideal. Therefore, the microbial group is in an extremely close symbiosis between the animal body. Rumen microorganisms affect the digestion, absorption and metabolism of ruminants, and the metabolic activities of ruminants also affect the proportional relationship between tumor stomasia. One of the characteristics of ruminants is to utilize a large amount of cellulose, and the cellulose is broken down into the simplest sugar in a pretty cellulose microorganism. The activity of microbial decomposing cellulose is affected by a variety of factors, such as the diet of the animal, the source of cellulose, and the level of the crude feed. It is expected that the cellulose levels in the diet have an important influence on the growth and metabolic activity of the decomposition of cellulose microbial groups in the raft of the livestock in the stomach. When the cellulose is 17%, the microbial group in the rumen has the greatest digestive ability of cellulose. When the cellulose level is less than 13% and above 22%, the microbial group is reduced to the digestive ability of cellulose. Therefore, the cellulose contained in the diet is an important effect on the type, proportion, proportion, proportion, proportion, and bacteria, and bacteria to nutrients and various growth factors. 2. The number and proportion of various bacteria in the rumen bacteria have differently varied with the composition of the grain. The interrelation between bacteria is mainly manifested as a synergistic effect, such as the interaction of cellulose decomposition and non-cellulose decomposition; another product of many rumen bacterial fermentation, and succinic acid in the rumen liquid Further, it is rapidly decarboxylated by other bacteria to form propionic acid and carbon dioxide. Taking succinate and ruminant primary monoth cells as an example, the anaerobic acid bacteria in cellulose decomposing bacteria, fiberSui fermentation produces succinic acid, acetic acid, and formic acid; ruminant silver bacteria with sugar decomposition products and succinic acid to produce propionic acid, acetic acid and carbon dioxide, and supply anaerobacterium CO2. CO2 and H2, etc. produced by bacterial resolution acid and other substances, and methyl methane is further synthesized by methane. There are synergies between rumen sugars, protein, and fat. This synergistic action between the rumen in the rancinum is carried out normally. If the environmental conditions change (such as sudden transform feed, etc.), resulting in a flora disorder, but causes digestive disorders, leading to diseases such as ryese. 3. The relationship between rumen bacteria and phage is separated from a variety of phage, such as some of the phage in SERRATIA, and has active 6 phage in Streptococcus (Str. Durans). , Infected with infected activity in Different Bifidobacterium. A large phage such as the infection of pnemy is isolated from the stomach of the sheep. More than 40 types of phage have more than 20 morphological types in bacterial cells. Phage is specific for bacteria infections. The adsorption, nucleic acid injection and biological synthesis of bacteria in the ryese, nucleic acid injection and biological synthesis, resulting in a typical infection process of bacterial cleavage. There is also a gentle phage and spirobic phage in the rumen. Therefore, the change in phage community in the rumen is more than the previous imagination. The phage plays an important role in the rumen microbial ecosystem. It is a special factor in regulating the quantity of ruminants. The number of bacterial communities changes, and the metabolism of the microorganism is also adjusted. 4, the relationship between bacteria and cilia in rumeters and fungi in the nucleus, there is two relationships between antagonism and coordinated effects between bacteria and fibergust in rumen. When there is no bacteria in the rumen microbiological species, the number of bacteria has increased significantly. After vaccination, the number of bacteria in the rumeter is reduced, which may be due to the competition of coccidium and bacteria to food, as well as the result of parenting bacteria. According to test fiber, the non-protein-synthetic protein can not be directly prepared by cilia, it is the main source of protein desired by fiber, and the bacteria enzyme system also helps the nutrient metabolism of cisoff. Obviously, the growth and reproduction of cervillatts depends on rumen bacteria. On the other hand, the fiber can also have stimulating bacterial breeding.effect. For example, the decomposition of tumor gousolar, when the cellulose and bacteria are either alone, the dioxide of cellulose is 6.9%, 38.1% of bacteria; when the two coexist, the digestibility of cellulose is increased to 65.2%, far exceeding bacteria and cibluidic worms to the total sum of cellulose digestibility (45%). Even the bacteria culture is added to the bacterial culture medium and the cellulose digestibility can be increased to 55.6%. It can be seen that the fiber is highly temperature resistant to high temperature resistance, which can promote the growth and reproduction of bacterial growth. There is a coordination between bacteria and anaerobic fungi, and studies have shown that plant large fragments are degraded into small fragments and cause many gaps, which are conducive to the progression of rumen bacteria. Degradation. Therefore, in the process of mutual division of labor and synergies during the degradation of tumor stomach, and bacteria.
