Let's take a look at the requirements of pigsty design for the construction of environmentally-friendly pig farms.
First, the basic principles of pigsty design
The following principles should be considered in the design of bio-environmental piggery:
The principle of 1. zero polyculture does not allow pigs from different sources to be polyculture, so the preparation of isolation houses should be considered.
2. The principle of optimal stocking always keeps pen, which requires balanced arrangement of reproductive production.
3. According to the principle of grouping pigs of the same age, pigs at different stages cannot be raised together, and a feeding system of all in and all out should be implemented.
Second, the envelope construction requirements
Using bio-environmental protection technology to raise pigs, the moisture in feces and urine discharged by pigs is evaporated by transpiration of heat generated by padding fermentation.
At the same time, practice shows that the control of high temperature in summer and high humidity in winter should be strengthened for the bio-environmental protection pig raising method.
According to this feature, there are some necessary requirements for the enclosure structure, mainly in the following aspects.
(1) pigsty generally requires this pig-raising technology mode, and generally adopts a single-row large window fully open pigsty with a span of 8 ~ 13m and a clear height (from terrace to eaves) greater than 3.0m ..
The large window (2.2 m 2 m) is built 30~40 cm above the bedding surface to the eaves, which is convenient for negative pressure ventilation and warm-keeping measures.
The windows are open most of the year, which makes the pen house have good ventilation function.
The spacing between houses is generally10 ~15m, which is convenient for small excavators or forklifts to drive.
(2) Intake and drinking table A intake and drinking table should be set at the northern end of the pigsty, and the area of the intake table should not be too wide.
The general width is1.3 ~1.8m. ..
Install a material box (or tank) and a water dispenser at the appropriate position of the drinking table.
Generally, bowl-type automatic drinking fountains should be adopted.
In the pens where ordinary drinking fountains are used, a pool should be set below the drinking fountains, and a launching funnel and a drainage pipe should be installed to discharge the water leaked from the pigs when drinking water to the outside of the pigpen.
When pigs drink water, the water spilled on the ground will not flow into the padding to prevent dripping from wetting the padding.
The production technology of free feeding and free drinking is adopted for fattening pigs with padding.
There are two main methods: one is to use dry and wet feeders to feed and drink water freely on one device, which is convenient to install and disassemble, saves the area of feeding platform, saves labor and reduces feed waste; The other is the traditional trough.
No matter what method is used, it is necessary to ensure that food and water cannot be cut off, so that pigs have enough space to eat and drink.
