Hearing aid is a small electronic device that you wear in or behind your ear . It makes some sounds louder so that a person with hearing loss can listen , communicate , and participate more fully in daily activities . The hearing aid can help people hear more in both quiet and noisy situations.

Therefore, they are favored by a large number of farmers. However, pigs in fermentation beds are based on the principle of using microorganisms to raise pigs. It requires certain skill, especially the control of moisture is very important. Now I am taking the widely used and effective Golden Boron fermentation bed starter on the market as an example to illustrate the moisture control during the pig breeding process.
Jinbao fermentation bed fermentation agent is a new generation of microbiology products developed and produced by Beijing Huaxia Kangyuan Co., Ltd. The product contains a large number of bacterial species, and the quantity is extremely large. An average of one kilogram can produce a 10 square fermentation bed, and the use cost is low. The range is wide, and even when it is in a dry environment (such as dust in a dwelling) or in flooding, it can maintain a very high activity. However, these environments are not conducive to the work of fermentation beds, and we should try to avoid them.
The working range of the fermentation bed is about 65%. Too high or too low is not conducive to the decomposition of the feces. If there is a situation that is too dry (such as in piglets, because the density of the pigs is relatively small, there is less feces, so The fermentation bed is very dry and even dusty, which is not conducive to the breathing of piglets, or even cause pig tracheal diseases.) At this time, we should increase the breeding density appropriately, or spray regularly on the surface with a sprayer to increase the surface humidity of the fermentation bed. Dust prevails. If the fermentation bed becomes too wet (eg if the density is too large, the pig's excretion is large, or if it is soaked by rain, etc.), a portion of the litter should be cleared out, dried and then filled in, if the density is too large, The density of culture should be reduced. At the same time should be added a small amount of bacteria, splashed 30 grams per square meter Jinpo fermentation bed fermentation agent is appropriate.
