Site selection i. Durability: long-term/ short-term ii. Pig house position Shed Orientations: increasing temperature has a significant impact on odor generation. Buildings orientated with their long axis east-west will minimize the heat load; Shed Positioning: space naturally vented sheds from other buildings or trees by at least five times the height of the nearest building or large object, to maximize wind ventilation iii. Factors of infrastructure facilities: water, electricity etc. iv. Hygiene and safety Shed Ventilation: adequate ventilation is required to remove piggery gases, dust and odor, to control air temperature and relative humidity, to remove excess heat and moisture, to dilute and remove airborne disease organisms and maintain oxygen supply to the pigs. v.

Operating/ Management requirements i. Feeders and waterers ii. Manure cleaning equipments and tools iii. Furrowing facilities A typical pig shed design can contain the following features for farrowing accommodation: • Protective side rails to reduce overlays; • Freedom from draught s; • A creep area to allow piglets to escape the sow and eat creep feed without the sow eating it or protective rails to prevent piglets being crushed against the sides of pen walls; • Supplementary heat in creep area. Weaner Section: Newly weaned pigs require suitable environmental conditions to counter the abrupt changes that occur at weaning. A change in diet from milk to solid feed, mixing with other pigs and a change of environment can stress weaners, making them more susceptible to disease. Weaner pigs must be weaned into a warm, dry, draught free environment. Grower/Finisher Section: Grower/finisher housing can be described using t wo basic design types. • Pens in sheds - This is by far the most common system of housing growers. Sheds offer protection from the elements for both the pig and the producer. Close control and supervision of stock is possible with this system to get her with the ability to regulate the environment;

Pushpakumara | Advanced Technological Institute- Gampaha • Eco-hut design - These sheds are a low-cost housing alternative where pigs are housed in a litter bedded shelter which is constructed upon compacted soil or concrete pad with solid walls. Breeding Section: Dry sows are generally housed in a combination of individual stalls and group pens. Stalls are often used for the first five weeks of gestation to allow for individual feeding and attention, sows may be moved to group pens to complete their gestation period. Group housing of sows in “barn” type sheds without pens is less common due to difficulties encountered with feeding and management. Bill of Quantity (BOQ) sample Date Description Qty Unit Rate Total
