Hi
The nabard website has a project report on commercial piggery, please go through the same for your reference
Housing management:
1. Construct shed on dry and properly raised ground.
2. Avoid water-logging, marshy and heavy rainfall areas.
3. The side walls of the sheds should be 4-5 ft. high and remaining height should be fitted with GI pipes or wooden poles.
4. The walls should be plastered to make them damp proof.
5. The roof should be atleast 8-10 ft. high.
6. The pig stys should be well ventilated.
7. The floor should be pucca/hard, even, non-slippery, impervious, well sloped (3 cm per metre) and properly drained to remain dry and clean.
8. A feed trough space of 6-12 inches per pig should be provided.
9. The corners of feed troughs, drains and walls should be rounded for easy cleaning.
10. Provide adequate open space for each animal i.e. double the covered area
11. Provide proper shade and cool drinking water in summer.
12. Dispose of dung and urine properly.
13. Individual pens for boars/lactating sows should be constructed.
14. The dry sows/fatteners can be housed in group pens.
15. Give adequate space for the animals.
