First, no resistance is really far away from us?
The Ministry of Agriculture website September 7, 2015 news, the Ministry of Agriculture announced on September 1st No. 2292. According to Article 69 of the Regulations on the Administration of Veterinary Drugs, it was decided to stop the use of lomefloxacin, pefloxacin, ofloxacin and norfloxacin in food animals, and to revoke the approval number of the relevant veterinary drug products. The announcement pointed out that due to the large food safety hazards of these four APIs and their preparations, and the existence of animal-specific alternative products, it was decided to ban.
It can be seen that the domestic non-resistance process has made great strides, and the natural advantages such as the efficient and safe yeast cell wall also determine its irreplaceable position in non-resistant culture.
Second, the principle of yeast cell wall function?
1. Adsorption of mannooligosaccharides in the cell wall of pathogenic yeast cells, which can compete with pathogenic bacteria, hinder the adhesion of pathogenic bacteria on the intestinal wall, and adsorb and excrete.
2. Activation of β-glucan in the immune cell yeast cell wall acts on immune cell surface receptors, and activates the body to produce non-specific and specific immune responses through a series of pathways.
3. The special spatial structure provides more toxin binding sites, and stably adsorbs various mycotoxins through intermolecular forces such as hydrogen bonds and van der Waals forces to prevent the toxins from being absorbed by the intestines.
Third, where can the yeast cell wall be used? Is it really useful?
1. A large number of studies in the pig field have confirmed that the yeast cell wall can strengthen immune function, enhance anti-stress ability, reduce mycotoxin damage, and stabilize production. As of the end of 2014, Anqi Animal Nutrition Research Institute carried out research on yeast cell wall polysaccharides in the pig field for 9 times. The basic results are shown below.
2. A large number of studies in the poultry field have found that the yeast cell wall activates both specific and non-specific immunity, while reducing stress and stabilizing poultry production. As of the end of 2014, Anqi Animal Nutrition Research Institute carried out 17 animal studies on yeast cell wall polysaccharides in the poultry field.
3. field
The yeast cell wall acts as a highly potent immunopotentiator and is equally effective against ruminants. Zhou Yi (2010) found that adding β-glucan to weaned calf diet significantly increased serum IgG and IgM levels, reduced calf diarrhea, and alleviated a series of problems caused by E. coli K99 challenge. Ru Ru (2012) found that the addition of mannan to the diet in the dairy goat study can significantly reduce the amount of E. coli in the feces and increase the number of lactobacilli and bifidobacteria.
4. Aquatic field
Cell wall polysaccharides from yeast sources are the most widely used in aquaculture and are recognized as the most potent immunopotentiators in aquaculture (Meena, 2012).
Its biological functions are mainly summarized in the following aspects:
Improve the non-specific immunity of aquatic animals and significantly improve the disease resistance of aquatic animals;
Can effectively reduce liver damage;
Adsorb and discharge pathogens.
As of the end of 2014, Anqi Animal Nutrition Research Institute carried out research on yeast cell wall polysaccharides in the field of aquatic products 18 times.
Fourth, face no resistance, what can you do with the yeast cell wall?
With the anti-stepping approach, the livestock and fisheries industry will gradually achieve its stated goals from all aspects of breeding, environment, nutrition and management.
As a natural green, non-polluting and highly effective immunopotentiator, the yeast cell wall will play an important role together with other functional substances (acidifiers, extracts, etc.).
The Anqi Animal Nutrition Institute is working on a series of studies on the improvement and upgrading of yeast cell walls. For example, the combination of fully-replaced or semi-replaced commonly used feed antibiotics in different farmed animals will gradually share industry and market transformation.
Hydraulic Box Girder, where the main beam includes a beam in the shape of a hollow box. The box girder usually includes any prestressed concrete, structural steel, or composite material, and reinforced concrete. The box is usually rectangular or trapezoidal in cross section. Box girder bridges are usually used for modern elevated structure transportation of highway overpasses and light rails. Although box girder bridges are usually a form of girder bridge, box girder can also be used in cable-stayed bridges and other forms.
