There are mainly two sections of a piggery. These are the feeding and the exercise areas.
The feeding area must be covered by a roof to prevent the shelter from getting soaked, which can lead to many diseases, for example, abdominal complications.
This should constitute at least two-thirds of the entire piggery.
The other section is the exercise area. It is also the area where the pigs ease themselves. It should cover at least a third of the piggery.
It has to be a well-drained area, in a shade and away from the main house farmhouse.
It should be designed in a north-south orientation that it crosses the path of the sun not directly in the line of the sun.
To tell this, note that the sun rises from the east and sets in the west so your structure should be set with the sun passing on top of it.
It must be easy to clean. Remember, poor cleaning leads not only to diseases for the pigs, but also causes an awful smell for your neighbours.
This means that it must have a slant so that urine easily drains into a tunnel for collection into a storage reservoir.
The structure must have enough ventilation to allow easy flow of fresh air. Pigs, just like other animals, need fresh air to survive. Walls should not go over 4ft off the ground, with the rest left free to allow in air.
They must have adequate doors for the farmer to move in and out easily.
Before one enters a piggery, they should first disinfect. This is why a footbath with a disinfectant must be constructed at every entrance point. The solution should be changed every week.
