Pig-raising technology in the fermentation bed is to change the ground of the pigsty from the current cement floor to a new pig-raising mode with a fermentation function floor. Based on microbiological and ecological principles, it is a kind of environment-friendly breeding mode that uses a special compound microbiota to continuously and stably convert pig manure into gas, useful substances and energy, and achieve complete pollution of the excreta and zero discharge targets. According to whether the litter is fermented before entering the pig, the current fermentation bed technology is divided into wet fermentation bed and dry submerged fermentation bed.
Beijing Huaxia Kangyuan Technology Co., Ltd. Jinbao dry-type fermentation bed pig operating techniques are as follows:
1, housing structure
The pig house runs east and west, facing south, about 3 meters high and about 4.5 meters high. The rear window is about 1 meter high from the ground. The windows should be large, and the south window should be as large as possible or a shed style.
The single area of ​​the pigsty requires 20-45 square meters, as close as possible to a square.
The sow is 1.8 meters wide and 3-4 meters long and raises a sow.
The coils are preferably made of steel to facilitate ventilation, and generally do not use solid walls.
Four windows are complete. In addition to the usual windows and doors, add skylights and windows. In principle, fans and coolers should also be installed.
2. Fermentation pond construction
If the plot is high and dry, and the groundwater level is deep, 50-60 centimeters can be excavated in the pens for the fermentation tank. Protect the slope with cement mortar or brick walls. The bottom of the fermentation tank is a land surface and requires a level and dryness. If the groundwater level is shallow, the height of the fermentation tank should be properly raised, that is, the fermentation tank should be dug less or not. If necessary, the bottom surface of the fermentation tank can be compacted with triaxial soil to prevent water seepage. In principle, the fermentation tank of a pig house is a whole, not separated.
Below the drinking fountains, a cement bench (drainage table) with a surrounding high, low middle, and a size of about 0.4 square meters was built to drain the water that was leaking from the drinking fountain.
3, litter production
Sawdust is the preferred raw material for the production of goldfish dry fermentation mattresses, followed by rice hulls, peanut shells and various straws, requiring drying. Wet materials should be dried and mildew and toxic litter must be avoided.
Calculate the amount of fermenting bacteria according to the area of ​​the fermentation bed. The fermented fungus was mixed evenly with corn flour, wheat bran or rice bran in a ratio of 1:5 and divided into five equal portions.
The padding materials are spread in five layers, and each layer is evenly sprinkled with a layer of bacteria. It can also be paved first after mixing the raw material and fungicide.
Pads can be fed immediately after laying.
4, management and maintenance
The waste gas and water vapor in the pigsty should be discharged in a timely manner.
The pig's excreta should be blended with litter in a timely manner and buried under 10 cm below the surface of the litter.
The compacted litter was turned in time.
When the litter has dried out of dust, a small amount of water can be sprayed on the surface.
Every four months or so, or to raise a batch of pigs, to reduce the amount of padding to be added to the pad to add a corresponding proportion of microbial agents.
Promptly check and maintain the drinking fountain to prevent water leakage.
Prevent rain and groundwater from entering the litter.
The breeding density of pigs is reasonable. Pigs occupy 0.5-0.8 square meters of fermented bed area per head, 75 kg or more of pigs occupy more than 1.5 square meters of area, especially about 2.0 in summer.
