Efficient Design and Construction of Small-Scale Piggery Units
Efficient design and construction practices for small-scale piggery units are crucial for successful pig farming. This includes considerations for layout, ventilation, environmental factors, and structural components like roofs and floors.

Good ventilation and a cool environment reduce the stress on the pigs minimizing disease and improving growth. Well elevated and open to the prevailing daytime wind to maximize cooling for the pigs during the hot day time temperatures. Sea Breezes The sheds should be aligned for the sun on an East West axis as, whilst the breezes can be diverted, the sun is a constant.
Ideally on a slope to allow gravity to move water and effluent through the piggery The piggery should be located distant from any water course. Road access is relatively important particularly if feed needs to be delivered Water is an essential service. Each pig will require up to 25 lts per day for drinking and washing. The provision electricity may not be necessary (unless pumps are required) Mobile phones will suffice.
Lean to structure with the roof supported on a grid of posts at 4m centers. The sides are open to allow good ventilation. The floor is a strong reinforced concrete slab 25 (mpa) laid to falls of 1 in 40. Various partition types are included for different classes of pigs. The zincalume roof is supported on double rafters (200mm by 50mm) Purlins (100mm by 50 mm) at 1.2m centers. Additional strength is gained by wire cross bracing and strapping. Because of the modular design of the unit it is relatively simple to either add or subtract pens to meet the needs of specific designs and stock numbers.
