The litter production process is actually a process of mating materials and starting fermentation. On the one hand, the purpose is to proliferate a considerable number of beneficial predominant microflora in the litter to prepare pigs for housing; on the other hand, the calories generated during the fermentation process Kill harmful bacteria and viruses. Step 5: Spread the fermented litter in the pig house and add 100 kilograms of dry lean loess. (Soil that has not been polluted by the environment) Of course, the start of maturation and maturation of the litter needs to meet the start-up requirements, in particular, the temperature requirement is very important. The high temperature in summer can meet the temperature start requirement. The temperature in the northern part of the country is relatively low in winter, and the temperature of the fermentation environment can be increased by measures such as heating by the stove and raising the temperature at the room temperature.
1.Store in dry and cool condition, keep away from material with odor or of volatilization, protect from water and wet.
2.Best within 24 months from manufacturing date.

First, the calculation of a good amount of raw material fermentation bed is able to combine the needs of pig production, scientific adjustment of the type and amount of raw material for each litter, to achieve the best growth and reproduction state of the fermentation of bacteria? A medium. Therefore, according to the basic requirements of litter, at the same time combined with the physical characteristics of various raw materials and the growth of pigs to calculate the amount of litter raw materials. Different raw materials and different seasons account for different A ratios. The basic production ratio (volume ratio) is sawdust: rice husk = 1:1.
Second, the production process
1, raw materials: sawdust: water absorption, water retention material. Husk, straw, peanut shells and other breathable substances.
2, the proportion of the volume: sawdust and rice hull account for 50% each, in order to increase the fermentation power in winter, the proportion of rice hull can be increased to 60%. The sawdust ratio must not be less than 30%. Sawdust can all be used.
3, data calculation and operation methods: (1) chemical fertilizer bags, woven bags calculation. A cubic total of 7 bags of litter, sawdust, rice husk each 3,5 bags. (2) Weight calculation: Take 80 cm deep and 10 square area as an example, you need about 1000 pounds of sawdust and about 500 pounds of rice husk. (3) Calculate by heap: According to the area of ​​fermentation bed, square. 80 cm deep area 10 square meters, volume is 8 cubic meters of padding material accumulation fermentation: (10 square meters fermentation bed area as an example)
The first step: 50 kg of rice bran or bran is added to the Ferguson Fermentation Bed Bacteria and stirred evenly. (After diluting 5 kg broth to 20 kg of water, mix it with rice bran)
The second step: Stir the rice bran or bran in the first step and mix well with a cubic dunnage.
Step 3: Mix the well-stirred material in the second step with the remaining 9 cubic liters thoroughly and mix evenly. In the mixing process, use 5 kg of Ferguson Fermentation Bed Bacteria liquid to water 500 kg of water (also melt in water 7 Livestock salt, to keep litter moisture at 50%. (How much water is the key, usually 50% is more appropriate, the field practice is to use hand grab litter to judge, identification methods: hand can be a group, loose hands and scattered, the hands feel the water, finger joints water seepage )
Step 4: Build trapezoids in the pens, cover them with sacks or straw, 3-5 days in summer and 4-6 days in winter. (The smell of fermentation and the release of steam) are generally based on temperature.
Precautions:
1, the principle of litter production: a variety of materials as far as possible mix, moisture control at 50%.
2. To make a large area of ​​dunnage, try to choose a large space to stir the dunnage, you can use forklifts, mixers, excavators and other machinery.
3. According to the humidity of litter, 10 squares of litter use 10 kg of Ferguson Fermentation Bed Bacteria, less than water, and be filled with fresh water, until the litter moisture is 50%. The field practice is to use hand grab litter Judgment, identification methods: hands can be grouped, loose hands are scattered, the hands feel the water, finger joints water seepage.
4. Stir the well-made padding must be used for fermentation. The thickness of the bedding bed is an important factor in determining the temperature. Generally, the thickness of the fermented mattress material is 80cm, and the area of ​​a single bedding area is not less than 20 square meters. If the litter is too thin and the floor area is too small, the heat generated by the fermentation is quickly lost, and the temperature of the fermented litter is difficult to reach a suitable temperature, so that the proliferation of the fermenting microorganisms is limited, resulting in no fermentation. The top is covered with grasshoppers, woven bags, and other insulating, air-permeable substances.
5. During the fermentation, measure the fermentation temperature daily and make a record. From the second day, the temperature was measured at a depth of about 20 cm at three points at different angles, and the temperature could rise to 40°C-50°C. If, after one week of fermentation, there is an increase in temperature and there is an odor, this is because there is too much water, so adjust the moisture again and add part of the broth to ferment until it is successful.
The spread of the fermented litter should be paved. In order to prevent litter on the surface of the litter, some water may be sprinkled properly to prevent dust. Then wait 24 hours before entering the pig.
