Description

Solid-state fermentation traditional Chinese medicine additive for replacing antibiotics to prevent diarrhea of nursery piglets

Technical Field

The invention relates to the technical field of fermented traditional Chinese medicine additives, in particular to a solid-state fermented traditional Chinese medicine additive for preventing and nursing piglet diarrhea by replacing antibiotics.

Background

In modern pig raising production, the phenomenon of diarrhea of weaned piglets is serious, and the reason is also complicated. However, the diarrhea of the weaned piglets is not easy to be paid attention to, some diseases seriously form the cad pigs and even die, and direct and huge economic influence is brought to the pig raising production. The reason for causing diarrhea in weaned piglets is as follows:

the self factors are as follows: the digestion ability is not good. The gastrointestinal digestive system of the newborn piglet is not completely developed, and the newborn piglet can grow by depending on rich nutrition in breast milk in the lactation period. But in a period of time after weaning, the gastric acid secretion in the bodies of the piglets is insufficient, and the content of digestive enzymes is in a lower level, so that some undigested protein feeds are fermented in small intestines, the normal flora proportion of the small intestines is disturbed, pathogenic escherichia coli rapidly grow, and then small intestinal mucosa is badly stimulated, and diarrhea symptoms appear. The immune system is immature. Most mammals rely on breast milk for active immunity for a period of time after birth. The active immune acquisition pathway is cut off after weaning, and the weaning is also a stress, which has a plurality of adverse effects on the development of the immune system of the piglets. The antibody level in the piglet body is low, the resistance to the change of the external environment is weak, a plurality of hotbed environments in a pigsty are not ideal, and a plurality of pathogenic bacteria can enter in a conquering way to cause diarrhea of the weaned piglet.

Environmental factors: the temperature difference in the house is too large. The fat layer of the piglet is thin and is not enough to resist large external temperature difference change. When the temperature change in the piggery exceeds 10 ℃, the digestive system of the piglets is obstructed. Research shows that in a certain temperature difference range, the possibility of diarrhea of piglets is increased by about 30% when the temperature changes by more than 10 ℃.

The feed proportioning is not scientific: although a certain amount of fiber can be digested by a pig serving as a omnivorous animal, the digestive organs of piglets lack enough enzymes capable of digesting the cellulose, so that the fiber feed cannot be fully digested in intestinal tracts of the piglets, gastrointestinal mucosa of the piglets is damaged, normal flora of the intestinal tracts is damaged, and diarrhea is caused.

Threat of pathogenic bacteria. Digestive tract diseases are mostly caused by contamination with pathogenic microorganisms. In a pig farm, the potential threat of various pathogenic bacteria can be generated once a scientific disinfection process is lacked. The most common of these are E.coli and Salmonella. This is often the case in current pig farms where the diarrhea is common and once the piglets become infected with such pathogenic microorganisms, they are difficult to treat.

The conventional method for preventing and nursing piglets comprises the following steps: florfenicol, neomycin, quinolone and other medicines are generally selected, and the florfenicol, neomycin, quinolone and other medicines are matched to obtain better effects such as Shuanghuanglian, atropine, glucose, camphor, vitamin and the like. Secondly, in the treatment process, comprehensive measures such as laxation, antibiosis and antiphlogosis, fluid infusion, cardiotonic, nutrition, heat preservation, pressure prevention and the like must be adhered to.

The method reduces the diarrhea of the weaned piglets to a certain extent, but the drug resistance of the piglets is increased by using the antibiotics for a long time, and the effect is worse and worse.

Therefore, the application provides a solid-state fermentation traditional Chinese medicine additive for replacing antibiotics to prevent diarrhea of nursery pigs and a preparation method thereof.

The result shows that the sophora flavescens has a certain antibacterial effect on MRSA clinical strains. Qinqinging and the like adopt a standard agar plate double dilution method to measure the Minimum Inhibitory Concentration (MIC) of emodin, berberine, matrine, baicalin and the like to sensitive and drug-resistant escherichia coli, and observe the inhibition effect of the traditional Chinese medicine extract to the sensitive and drug-resistant escherichia coli. The results showed that the MIC of matrine to sensitive E.coli was 64. mu.g/mL and the MIC to drug resistant E.coli was 128. mu.g/mL. The matrine has certain inhibition effect on sensitive and drug-resistant escherichia coli. The Huang-Yan Qiang adopts a standard agar plate double dilution method to measure the Minimum Inhibitory Concentration (MIC) of emodin, berberine, matrine, baicalin and the like to the drug-resistant helicobacter pylori, detects the absorbance (A) value of a reaction hole after the strain acts on the MIC drug, observes the formation condition of the drug-resistant helicobacter pylori biofilm through a confocal microscope, and observes the influence of the traditional Chinese medicine extract on the formation of the drug-resistant helicobacter pylori biofilm. The results show that the MIC of matrine to drug-resistant helicobacter pylori is 128 mug/mL, and the biofilm formation under a confocal microscope is obviously less when the matrine is 64 mug/mL. The matrine is suggested to have an inhibiting effect on drug-resistant helicobacter pylori, and the concentration of MIC is less than 50 percent, so that the matrine can obviously inhibit the formation of bacterial strain biofilms. The mansion tourmaline and the like show that the kusheng water decoction has obvious inhibition effect on escherichia coli, staphylococcus aureus, streptococcus A, streptococcus B, dysentery bacillus, salmonella weizili and proteus.

Stimulation of intestinal mucosal immunity by probiotics: the microecological preparation is taken up by the specific M cells in the Peyer's disease knot on the mucosa after entering the digestive tract, is transferred to the antigen presenting cells in PP, induces T cells to generate IL-4, IL-10 and transfer factor by low-dose antigen, inhibits the differentiation of Th1 cells, enables the organism to generate oral tolerance, enables Th0 cells to differentiate to Th1 cells, and stimulates B cells to secrete IgE. High doses of antigen can lead to clonal anergy, T cells are in a cell unresponsive state, T cells are unable to secrete IL-2 and proliferate. The most suitable dosage of antigen can promote the differentiation of Th0 cells to Th1 cells, Th1 cells can promote B cells to secrete SIgA and inhibit IgE secretion, and some cytokines produced by the antigen can inhibit the growth of virus.
