Several main influencing factors of fermentation bed aquaculture operation
Fermentation bed culture technology refers to the comprehensive utilization of the principles of microbiology, ecology, and fermentation engineering, and the use of active functional microorganisms as an ecological breeding mode for material energy. The core of this technology lies in the use of a powerful microbial compound flora with beneficial functions to convert animal waste into useful substances and energy for a long period of time and steadily, and at the same time to achieve complete degradation of excrement of pigs and other animals to achieve no pollution. Zero emissions goals. The decomposition ability of the fermentation bed depends mainly on the viability of the fermentation bed strain (for details, please click). The stronger the viability of the bacteria, the more prosperous the metabolism will be, and the better the fermentation bed will operate. The main factors affecting the operation of the fermentation bed include the following points for your reference:
Fermentation bed decomposes feces mainly by bacteria species, the species, activity and quantity of each company's manufacturers are not the same, bacteria species should choose large manufacturers, can promote each other without antagonistic strains, Jinbao dry type fermentation bed strains It is mainly composed of filamentous fungi, yeasts, actinomycetes, and other natural beneficial microflora. It is produced through special processes such as high-tech screening, purification, and rejuvenation. It promotes each other and does not antagonize each other. The strains have strong activity and quantity, and the amount of bacteria per gram is equal to or greater than 3.5 billion.
The litter is mainly to provide an environment for the survival and reproduction of bacteria. The reproduction of bacteria needs a reasonable ratio of carbon to nitrogen (25-30): 1. The manure mainly provides the nitrogen source, and the litter mainly provides the carbon source, so the litter ratio is carbon and nitrogen. The higher the fermentation bed is, the longer the service life is. In general, sawdust "cotton rod" rice husk "corn stalk.
Breathability of the fermentation bed is related to the respiration of strains, because the fermentation bed strains are all oxygen-consuming strains and need oxygen, so many mattress materials need to be mixed with rice husk and sawdust, but the goldfish fermentation bed strains Strong activity, good dormancy, even if all use sawdust as a litter, bacteria can survive well. After animals produce feces, they need to regularly turn over the litter. First, increase the air permeability. In addition, the feces can be fully contacted with litter and bacteria to achieve the purpose of fermentation and decomposition.
The lower thickness of the fermentation mattress material ensures contact with the ground to prevent moisture and water corrosion. The middle layer ensures the normal fermentation of bacteria and feces. It is the core layer of fermentation, and the upper layer is a heat insulation layer and a protective layer, and can also be used for pig archivore protein bacteria. Therefore, the thickness of the litter directly affects the working conditions of the fermentation bed. According to the different types of culture and the amount of feces, paving materials of different thicknesses are laid. Generally, the thickness of pig litter is required to be 50 centimeters, and the thickness of the litter for chickens, ducks and gooses is 40 centimeters. .
The normal operation of the fermentation bed requires a certain degree of humidity. The strains of Gumba dry-sweeping fermentation bed use the moisture in the animal's excrement to start the decomposition of the fermentation. Without fermentation, the manure does not ferment and is in a dormant state, effectively prolonging the fermentation bed. The service life of Tycoon dry-type fermentation bed is not afraid of dryness. If the bed is too wet, it will cause an anaerobic environment in the fermentation bed, which will cause death of the bacteria and result in dead bed. Therefore, pay attention to the humidity of the fermentation bed during the use of the fermentation bed. Prevent the water in the drinking trough from flowing into the fermentation bed and prevent the rain from soaking the fermentation bed. If the amount of animal excrement is too high and the humidity is too high, it is necessary to suspend the use of the fermentation bed or reduce the cultivation density.
Reasonable breeding density is mainly to control the amount of animal feces, too high density will cause too much feces, fermentation bed humidity is too large and bad bed, farmers in the normal work of the fermentation bed, you can adjust the density according to the actual situation, has reached The best breeding density does not waste aquaculture area, nor does it cause a bad bed in the fermentation bed.
The fermentation bed is not a panacea. It is not a matter of managing the fermentation bed. The fermentation bed also needs normal maintenance and maintenance. In order to achieve the maximum efficiency and minimum investment in aquaculture, the majority of farmers need to observe the use of the fermentation bed at any time. , timely communication with Beijing Huaxia Kangyuan business technical personnel.

Feline Infectious Peritonitis (FIP), referred to as Feline Infectious Peritonitis (FIP), is a fatal abnormal immune response that occurs in cats. It is caused by the mutation of the feline coronavirus carried by cats. As a high-incidence and fatal disease of pet cats, the current incidence of feline abdominal transmission is about 10%.
The symptoms of cats are usually divided into two categories, namely wet FIP and dry FIP, of which wet FIP accounts for the majority of all cases. About 70%, manifested as abdominal pleural effusion, abnormal bulging; dry FIP cats have different symptoms, depending on the type of organ affected by the virus.
So far, all feline feline feline treatments are based on the characteristics of the disease, and GS-441524 can play a role in the treatment of feline feline disease. Therefore, the therapeutic effect of GS-441524 is obviously more ideal, the dose used is less, the treatment cycle is shorter, and the efficacy, safety and convenience of operation are all good. Because of this, GS-441524 is considered by many pet owners and veterinarians to be a magic medicine that can effectively treat feline abdominal infection.
