Construction guidelines for farm
Construction guidelines for farm
1. Flooring
- Flooring should be made of cement concrete with a rough/grooved surface to prevent slipping
- It must be impervious (non-absorbent) and easy to clean
- Provide a proper slope for drainage (approximately 3 cm per 2 m length)
- Floor should be constructed using conventional masonry with cement mortar
- Proper drainage channels must be provided for effective disposal of waste and effluents
2. Pig Sties (Housing Environment)
- Adequate shade should be provided, preferably by planting trees around the piggery
- Housing should protect pigs from extreme weather conditions
3. Floor Space Requirement for Different Categories of Pigs

6.0 – 7.5
8.8 – 12.0

General Guidelines
- Feeders and waterers should be placed inside the shed
- Ensure easy access for all pigs to avoid competition
Daily Water Requirement (Approx.)
- Boar: 40 – 50 litres/day
- Farrowing sow: 18 – 20 litres/day
- Fattening pigs: 3.5 – 4 litres/day
- Dry sow: 4 – 5 litres/day
Factors Affectig Water Requirement
- Age and body size of the animal
- Environmental temperature
- Humidity level
- Dry matter content of the feed
- Breed of pigs
- Adaptability to local conditions
- Season and prevailing weather conditions
- Number of suckling piglets
- Frequency of water supply
- Quality of feed provided
6. Quality of Water
Water provided to pigs should be:
- Clean and fresh
- Free from odour
- Colourless and tasteless
- Free from impurities and harmful substances
- Free from disease-causing organisms and parasitic eggs/larvae
7. Walls of Pig Houses
- Solid brick wall: up to 60 cm height
- Above brick wall: tubular iron (pipe) railings up to 150 cm
- Total wall height (for roofing): approximately 200 cm
8. Roofing of Pig Sties
- Roofing materials may include:
- Asbestos sheets
- Zinc sheets
- Tiles
- Coconut leaves (in low-cost housing)
- Height of side walls should be maintained at 2 to 2.5 metres
9. Doors
- Standard size: 2 m × 1 m
- Doors should be strong and fitted close to the floor
- This prevents pigs from lifting them with their snout
10. Guard Rails / Pig Fenders
Purpose:
- To prevent crushing of piglets by the sow in farrowing pens
Material:
- Galvanized iron pipes (about 5 cm diameter)
Construction Details:
- Height above floor: 25 cm
- Distance from wall: 20 cm
- Space between rails: 10 cm
Important Notes:
- Usually, weaker or less active piglets are more prone to crushing
- Piglets can move under the rails when the sow lies down, avoiding injury
- Requirement of guard rails may be reduced if pig brooders are used
11. Types of Pig Houses / Sties
1. Boar Sty
- Should be dry and well-ventilated
- Provide adequate resting/sleeping space
- Only one boar per pen
- Arrange boar pens in a row under a single roof
2. Dry Sow / Gilt Sty
- Can accommodate 3 to 10 animals per pen
- Dry sows and gilts can be housed together
3. Farrowing Pen
- Used for pregnant sow/gilt 2 weeks before farrowing
- Should provide enough space for sow and piglets during nursing period (12–14 days)
Size:
- 7.5 – 9 m² (approx. 8 × 10 ft)
Important Points:
- Ideal temperature: around 20°C
- Provide heating arrangements (e.g., electric bulbs) during winter
Floor Slope Advantage:
- Sloped floor helps sow lie towards higher side
- Piglets move to lower side, reducing crushing risk
Bedding:
- Provide 10–15 cm thick bedding, especially in winter
- Bedding should be clean, dry, and evenly spread
4. Fattening Pig Sty
- Capacity: 20–30 pigs per pen
- Used for pigs raised for market (meat production)
5. Weaner Sty
- For piglets from 8 weeks to 6 months of age
- Maximum 30 pigs per pen
