There are certain standards and norms in the construction of a piggery in a fermentation bed
First, the principle of building pigs
The general principle of the design of the fermentation bed is for the use of pig farms in construction or renovation.
(1) An area of ​​40 square meters per column is appropriate to facilitate daily maintenance of litter;
(2) The fermentation bed area is about 70% of the area of ​​the pens, and the remaining area should be hardened to become a hard ground platform for pigs to eat or rest in high summer temperatures;
(3) The height of litter should be 40-50cm for nursery pigs and 60-80cm for bred pigs. Generally, the padding in the south can be properly lowered, the padding in the north area should be properly raised, the padding in summer should be low, and the padding in winter should be appropriate;
(4) The breeding density of bred pigs is reduced by about 10% compared with conventional culture methods, which facilitates the timely and adequate decomposition of fecal urine excretions in the fermentation bed, and can maintain a healthy breeding environment;
(5) The import and export of litter shall be designed to meet the requirements of feeding and clearing (that is, it needs to be removed from the litter trough when the litter is used for a certain period of time);
(6) The humidifying device shall ensure that it can be shared when the padding is added during the later period;
(7) Ventilation facilities are complete. Wet curtains should be considered when heating in the south in summer. The fan should be turned on at regular intervals in winter to avoid excessive humidity in the pig house.
Second, the construction mode of the pig bed in the fermentation bed
(A) above ground mode
The litter trough is built on the ground. The bottom of the litter trough is the same as or slightly higher than the ground outside the pig house. The hard ground platform and the operating channel must be raised by 50-100cm (see Figure 2-2). The nursery pigs are about 50cm in length and are bred. About 100cm pigs, the side of the hard floor platform and the exterior of the pig house constitute a long slot equal to the pig house, and the middle of the pig needs to be divided into a number of bars by the iron fence to prevent the column.

Advantages: Keep the pig house dry, especially to prevent the rainy season from flooding in high groundwater areas.
Disadvantages: The cost is slightly higher.
Adaptation areas: Most of the southern regions; areas with high groundwater levels such as rivers, rivers, lakes, and seas; and pig farms with manure removal facilities.

(II) Underground tank mode
That is, the litter trough is constructed below the ground surface, the depth of the trough is 40-80cm, the nursery pig is about 40cm, and the pig is about 80cm. When the new pig farm is built, it can imitate the trough mode, excavate one underground trough at a time, and then iron. The fence is divided into several units. When the original pig house is remodeled, it is suitable to excavate the pits in the original ring fence.

Advantages: The winter fermentation bed has good insulation performance and the cost is lower than on the floor tank.
Disadvantages: slightly poor breathability, can not stay vents, fermentation bed daily maintenance workers.
Adapted areas: Northern areas with dry or low groundwater levels.
(c) Semi-subterranean trough mode
Also called the semi-groove model, that is, one half of the litter trough is built in the ground, and one half is built on the ground. The hard ground platform and the operating channel take back the soil from the excavated underground part, the trough depth is 50-90cm, and the nursery pig is 40-50cm. 80-90cm bred pigs, the construction and separation of the long groove on the same slot.
Advantages: The cost is lower than the previous two models, and the fermentation bed is easy to maintain.
Disadvantages: permeability is poorer than on the ground, not suitable for areas with high groundwater levels.
Adapt to the area: most of the north, southern slopes or high-profile areas.
