| 1 | Select a Suitable Location | Choose elevated, well-drained ground with reliable road access and adequate separation from other livestock areas. | A suitable location reduces flood, mud, transport, and biosecurity risks while making feed delivery, pig movement, and waste handling more efficient. | Confirm that the site is not prone to flooding; provide all-weather vehicle access; position clean and dirty traffic routes separately; check availability of electricity and clean water. | High |
| 2 | Plan an Efficient Internal Layout | Arrange rooms or pens in a logical flow: entry and changing area, receiving area, nursery pens, treatment area, feed storage, and manure route. | A one-way workflow limits unnecessary movement and helps workers identify sick piglets, clean pens, and deliver feed more efficiently. | Separate incoming piglets from outgoing animals; provide a dedicated isolation or treatment pen; avoid crossing feed paths with manure paths; keep inspection routes visible and unobstructed. | High |
| 3 | Allow Adequate Floor Space | Plan approximately 0.30–0.40 m² of usable floor space per nursery piglet, adjusted for body weight, climate, flooring, and management system. | Overcrowding increases competition, fouling, heat stress, injuries, and disease pressure. Space requirements should be reviewed as piglets grow. | Calculate usable pen area rather than total building area; exclude feeders, drinkers, partitions, and fixed equipment; set a maximum group size before stocking; reserve space for growth toward the end of the nursery period. | High |
| 4 | Check Ventilation and Air Quality | Use adjustable air inlets and exhaust capacity that provide fresh air without creating drafts at piglet level. Keep ammonia preferably below 10 ppm and investigate persistent levels above 20 ppm. | Good ventilation removes moisture, dust, carbon dioxide, and ammonia while helping control temperature. Poor airflow can contribute to respiratory problems and uneven growth. | Inspect airflow at piglet height; avoid direct drafts on resting areas; install sensors or regularly measure temperature, humidity, and ammonia; provide backup ventilation or alarms where practical. | High |
| 5 | Design Temperature-Zoned Pens | Provide a warm, draft-free resting zone and a cooler activity or dunging zone. Newly weaned piglets commonly need an initial room temperature around 24–28°C, adjusted according to weight, bedding, and behavior. | Small or recently weaned piglets have limited ability to regulate body temperature. Zoning lets them choose a comfortable area and reduces chilling or overheating. | Use heating plates, floor heating, or safe radiant heat where needed; insulate the building envelope; observe huddling, shivering, panting, and lying patterns; install thermostatic controls and protective guards. | High |
| 6 | Evaluate Flooring, Drainage, and Hygiene | Use non-slip, cleanable flooring with adequate drainage. Where slatted flooring is used, openings must be suitable for piglet size and must not create leg or hoof entrapment hazards. | Dry, stable flooring supports mobility and reduces injury, skin damage, contamination, and heat loss. Effective drainage also shortens cleaning and drying time. | Check floor traction when wet; eliminate sharp edges and broken slats; slope solid areas toward drains where appropriate; verify that surfaces can be washed, disinfected, and dried between batches. | High |
| 7 | Provide Accessible Feed and Water Points | Supply clean water continuously through correctly adjusted drinkers and provide enough feeder access to reduce competition, especially during the first days after weaning. | Easy access to water and feed supports early intake, gut adaptation, uniform growth, and recovery from weaning stress. | Test water flow and quality regularly; place drinkers at suitable height for piglet size; keep feeders away from dunging areas; provide extra access during the transition period; inspect equipment daily for blockage or leakage. | Medium–High |
