More and more farmers have already used the environment-friendly breeding mode - ecological fermentation bed aquaculture technology. It is believed that the function of the fermentation bed is no longer unfamiliar. However, there are still some doubts about dry fermentation beds, such as: litter does not need to adjust the water, and functional microbes play a role in the required moisture content of 65%, and as long as the microbial fermentation of the NutriRiver fermentation bed, do not need to add water How does that moisture come from?
At present, the fermentation bed aquaculture technology is divided into two categories: one is a wet fermentation bed, and the other is a more scientific, more advanced dry-sanding fermentation bed represented by the Ginba dry-type fermentation bed (for details, please click). Friends who have experience in breeding know that the greater the moisture in the pigpen, chicken house or duck house, the more likely the animals are to get respiratory diseases. The large moisture in the air is more conducive to the breeding and growth of diseased bacteria. In general, some hay is placed inside the pens to absorb the moisture in the air. The customers who have made wet fermentation beds report to us that other farmers are not recommended to use wet fermentation beds. First, fermentation in advance consumes carbon nutrients in the litter and shortens the fermentation life of litter. At the same time, under the moist condition, even if it does not participate in fermentation of excrement, its nutrients will slowly decompose and consume. The second is that in terms of carbon supplements, wet fermentation techniques do not allow adequate fermentation of litter, less litter for pigs, fewer new litters, and insufficient carbon nutrition. Third, the efficiency of producing ammonia and other gases in the fermentation process is low, and excrement is accumulated in the litter. The fourth is to add salt in advance to increase the salt concentration in the litter. The lack of new litter can not fully dilute the salt concentration, resulting in more failure of the final application.
The source of moisture for the ginba dry-type fermentation bed is as follows:
(1) Sawdust itself: If it is fresh sawdust, such as sawdust after processing such as Chinese fir, eucalyptus, and miscellaneous wood, the water content varies greatly depending on the species of the tree, generally 50-60%, if it is Aged dry sawdust is usually calculated as 25-30%;
(2) Excreta of pigs: The fecal excretion of pigs per day has a water content of about 45%, which can be ignored. Urine occupies a large proportion. Each pig is calculated based on the excretion of 4 kilograms per day. The 15 to 17 finishing pigs in the 30-m2 fermentation bed are 60-68 kilograms of water. This is a considerable part of the water source, so no water can be added.
(3) Other residues of drinking water, feed residues, and sometimes caused by artificial feeding (but note that we must avoid extravasation of rain), this is a very small part.
When the moisture does not meet the requirements, the functions of the microbes will be dormant or the fermentation will slow down. When the requirements are met, the functional microbes will exert the best effect, start to decompose and ferment, and eventually achieve deodorization, environmental protection, and energy saving. , Save water and save labor, improve animal disease resistance, thereby increasing the user's economic benefits. This is why the goldfish fermentation bed can run without adding water.
The dry-spreading fermentation bed does not need to be fermented in advance. It does not obviously consume its own decomposition, and does not waste the nutrients of the litter. The waste is decomposed completely and the residual material is less; the salt does not increase the salt burden; the new padding is added, and the carbon is increased. Nutrition supply, dilute salt concentration. From a theoretical analysis, the dry spreader can run for many years.
Practice has proved that as long as normal maintenance is maintained, the dry-sweeping fermentation bed is fully assured of continuous operation for more than three or five years. Even if the fermentation fails due to excessive accumulation of feces and urine, as long as the pigs are transferred and the fermentation bed is allowed to rest for two or three weeks, the excrement will be fermented and the water will evaporate, and the fermentation function will be fully restored. After the initial investment in the dry-sweeping fermentation bed, it can be properly maintained in 3-5 years and the overall cost is low. For long-term benefits, farmers can choose to ring the Dangdang brand—Gemba dry fermented bed.
