The users who have been using fermentation beds have had some questions: What are the standards for the use of fermented mattress materials and how much it changes over time? How can we determine the service life? Beijing Huaxia Kangyuan’s senior technology today. The experts answered some questions for everyone and provided some help to help everyone use good fermentation beds, do a good job of breeding, and quickly get on the road to prosperity.
1, fermented mattress material should be how to choose?
Spent sawdust is the preferred material for fermentation mattresses, followed by rice husks, followed by straw, peanut hulls, vinegar, and other materials (when the granules are rich, these materials are generally not used sparingly or used in the lower part). The litter is dominated by sawdust and rice hulls: sawdust can be used completely, or 70% sawdust, 30% rice hull, and the proportion of rice husks should not exceed 30%. The choice of sawdust: (1) non-toxic harmless, uniform texture, no formaldehyde fumigation; (2) water should be below 40%, in principle, the more dry the better; (3) sawdust fineness is generally between 4-40 mesh , Should not be too fine, the maximum diameter or length should not exceed 0.5cm; (4) Generally selected sawdust are all kinds of trees, mixed wood sawdust, poplar sawdust soft texture, poor water absorption, fast consumption, generally not too much, or Do not choose. The choice of rice husk: choose dry rice husk, do not choose rice husk powder.
2. What is the color change of the fermented mattress material over time?
Fermentation mattress material layer can be divided into five layers: protective layer, buffer layer, core fermentation bed, buffer layer, protective layer, can also be roughly divided into three layers: protective layer, core fermentation layer, buffer layer. The duck bed (40 cm thick) is divided into three layers. The protective layer is 5 cm, the core fermentation layer is 25 cm, and the buffer layer is 10 cm. In general use for 3 months, there will be a change in the upper 20 centimeters, and there will be no significant change in the lower 20 centimeters; if it is used for six months, there will be a change in the upper 30 centimeters and there will be no change in the buffer layer; if it is used for more than one year, the entire litter layer will change and the protective layer And the buffer layer has a large moisture content (buffer layer absorbs water due to moisture on the ground and generally has relatively large moisture content), and the core fermentation layer is moderate. For 2 or more years, consider replacing a batch of dunnage.
3, the length of life of fermentation mattress material?
Choice of full sawdust or 70% sawdust, 30% rice husk is better, and the use of a longer time
Specific can see the following table:
Rabies Vaccine After Animal Bite
Rabies is a viral infection transmitted by saliva of infected mammals, most commonly wild, terrestrial carnivores (e.g., skunks, raccoons, foxes, coyotes) or bats.rabies virus usually moves along a neural pathway and enters the CNS. After entrance into the CNS, the virus is unlikely to be affected by antirabies antibodies and encephalomyelitis usually develops and almost always is fatal. Vaccination of rabies vaccine in a timely manner is mandatory.
