Why Pigs in Fermented Bed Houses Rarely Have Diarrhea Pigs in the excreta contain large amounts of undigested organic matter, such as animal proteins, plant proteins, oils and fats. Untreated excreta contain odor components, harmful microorganisms, and a large amount of Hydrogen sulfide, alcohols, phenols, aldehydes, ammonia, amides and other pollutants. If the urine is directly pulled on the concrete floor, the harmful microorganisms will multiply. The pathogenic bacteria will also spread and spread. The bacteria will pass through the air and drinking water. , feed, etc. into the pigs, which leads to diarrhea in pigs. However, this phenomenon will have a fundamental change once the fermentation bed model is adopted. Fertilizer pigs can achieve these effects, relying mainly on beneficial functional microorganisms. If there is no decomposing protein or fat in the stool, it will enter the bedding of the fermentation bed and continue to decompose with sawdust, rice husks, etc. under the action of microorganisms to generate crude protein and then become bacterial proteins, etc.; harmful microorganisms and pathogens enter the beneficial microorganisms. Micro-ecological environment composed of bacteria, in which the continuous high temperature (below 10 cm below the surface of the fermentation bed is maintained at 40-60°C for a year, the higher the temperature is, the lower the temperature is), rich in organic acids, antimicrobial peptides, etc. can kill viruses quickly and lastingly. And harmful germs. Studies have shown that the coronavirus is sensitive to temperature and grows well at 33°C, but it can be inhibited at 35°C and can be killed at 36.9°C; E. coli and Salmonella are more resistant to heat, After 60 minutes at 55°C or heating at 60°C for 15 minutes, it still cannot be completely killed. It is difficult to kill E. coli and Salmonella with simple high temperatures. Therefore, there have been many reports that the high temperature of the fermentation bed can kill E. coli and Salmonella. This is Unscientifically, E. coli and Salmonella can be killed by the fermentation bed not because of high temperature, but because the antimicrobial peptides and organic acids produced by the Vita bacteria have a strong killing effect on E. coli and other pathogens; It is in the form of oocysts, and the oocysts are very resistant to disinfecting drugs. Therefore, it is always a difficult problem for conventional cement cages to house pigs to eradicate coccidiosis, but pigs are not worried about coccidia in the fermentation bed. Disease, because the coccidial oocysts are killed at a temperature of 55°C for 15 minutes. Because the development of coccidia oocysts requires continuous nutrients, conventional cement housing can provide it with continuous excrement. But in the manure fermentation bed in the pull down sheds ie decomposition is completed within 2-3 days, all of these environments are not suitable for the survival of parasite eggs.
The petri dish(Disposable Petri Dish), culture plate and elisa plate, all of them are made of high quality PS material. They are used for fungus, bacteria and other microorganism culture. The detachable Elisa plate is designed specially for ELISA. the whole strip is smooth and transparent without weld line on the bottom and the detachable plate, from 96well to 1 well can be randomly selected, greatly improving the flexibility of diagnosis and test.
Common Features:
â— Available in E.O. or Gamma radiation sterile.
â— Available in individual or bulk pack.
â— High strength carton package guarantees the transportation safety.
