Site Selection Good ventilation and a cool environment reduce the stress on the pigs minimizing disease and improving growth. The site selected should preferably be well elevated and open to the prevailing daytime wind to maximize cooling for the pigs The sheds should be aligned for the sun on an East West axis Wherever possible the site should be 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 important particularly if feed needs to be delivered to the site. Water is an essential service. Each pig will require up to 25 lts per day for drinking and washing.

Posts The lean to roof is supported by posts on a basic 3.6m grid or less. Posts should be located outside all pens The post suggested is a 4 inch by 4 inch wooden post or three inch C grade galvanized piping It is suggested that the posts are set in a post hole of at least 60 cm deep and 50 cm wide cut into solid ground rather than fill. The post should sit on a thin concrete pad and be encased encased in plastic waste pipe and filled with concrete
The Slab The slab is made of strong reinforced concrete. The depth of the slab should be 100mm and include 665 reinforcing mesh at a height of 50mm. The strength should be 25 mpa to stop pigs burrowing through the floor with their strong snouts. The slab should be laid to a fall of 1 in 40 from the center of the shed to each outside edge and a fall of 1 in 40 along the length of the shed. Where necessary starter bars should be set into the slab to hold the single line of blocks that will form the pens or for feed troughs.
