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 a fault in the microforgestal system, the balance is destroyed, causing micro-state disorders, resulting in a pretty stomach or digestive disease, and even affect the health of the entire body.

1, the relationship between tumor stomach microorganisms and hosts
The unique digestion process of ruminants is mainly manifested as the role of most of the substances in the feed in the microorganases in the rumen. . 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.
Tumor stomas microorganism affects the digestion, absorption and metabolism of ruminants, and the metabolic activities of ruminants also affect the ratio 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.
According to the experiment, the cellulose levels in the diet have an important influence on the growth and metabolic activity of resolving cellulose microbial groups in the raft of the livestock in diet. 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 relationship between rumen bacteria
The number and proportion of various bacteria in the rumen, changes with the composition of the day. 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.
Produced in succinate andAnti-mildinals are used as examples, and the anaerobic acid bacteria in cellulose decomposing is succinate, and cellulose fermentation produces succinic acid, acetic acid and formic acid; ruminant monasca bacteria with sugar decomposition products and succinic acid For nutrition, the succinic acid and the like were decomposed to produce propionic acid, acetic acid and carbon dioxide, and supplied 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 effect between the rumen in the flour stomach is normal for the digestive metabolism of the lysal substance. 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
Separated from a variety of phage, such as some of the phage in SERRATIA, Str.durans There is a phage in which infected active infected bifidobacteria (Bifidobacterium) has active. 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 infection. 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 ryese of the tumor. 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 fiber in the rumen and anaerobic fungi
There are two relationships between antagonism and coordinated effects between bacteria and cibluo.
When there is no bacteria in the ryese microbial 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 synthesized by the protein, and the rumen bacteria are preyed by cormifrust, that is, the main source of the protein required for fiber, the sameThe enzyme system of bacteria also contributes to the nutritional metabolism of the cormifrust. Obviously, the growth and reproduction of cervillatts depends on rumen bacteria.

On the other hand, the fiber can also have the effect of stimulating bacterial reproduction. 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 caucillar contains high temperature resistant to the growth of bacterial growth and reproduction. 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. More farming
