The American name for the British Large White, one of the world's most influential commercial pigs — renowned for prolific, milky, long-lived sows and lean, fast growth. A foundation maternal breed in modern crossbred hybrid production.

Part of the Pig breeds
Recognized pig breeds — selectively bred for type, purpose, and appearance.
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Minimum
Pen + wallow + 3-sided shelter
≥ 50 sq ft per pig in pen, hog-rated fencing
A bare-minimum pen with ≥ 50 sq ft per pig, a wallow for thermoregulation, a 3-sided shelter, and hog-rated fencing (woven wire or hot wire). Pigs are herd animals — solo housing is poor welfare, keep at least a pair.

Recommended
Rotated paddock with shelter
1/8–1/4 acre per pig, rotated
Rotated paddocks of 1/8–1/4 acre per pig with a wallow, a barn or sturdy shelter, sturdy fencing, and a farrowing crate option for sows. Rotation prevents parasite build-up and gives fresh rooting ground.

Ideal
Managed pasture + woodland
Multi-acre rotation, woodland + wallow, herd of 4+
Managed pasture rotation with access to woodland for natural rooting, a wallow, shade, and a herd of 4+ for social structure. Heritage breeds in this setup preserve genetic diversity and express the full pig behavioural repertoire.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.

Newborn
Newborn mammals are nursed on their mother's milk. Many are born helpless — blind, deaf, and sparsely furred (altricial, as in dogs, cats, and rodents) — while others stand and follow within hours (precocial, as in hoofed livestock).

Juvenile
After weaning, juveniles grow quickly and become increasingly active, playful, and independent. Adult coat, proportions, and (in many species) the permanent teeth come in as they approach full size.

Adult
Adults reach full body size and sexual maturity, with the species' mature coat and build. Sexual dimorphism — differences in size, mane, horns, or markings — is pronounced in some mammals and subtle in others.
Senior
Senior animals show aging signs such as graying fur, reduced activity, and a greater need for veterinary monitoring of joints, teeth, and organ function. Lifespan and the onset of old age vary widely by species and size.
Habitat & enclosure
Needs a dry, draft-free shelter/hut with deep clean bedding plus an outdoor pasture or lot with secure, strong fencing (pigs root and push — use stock panels or hot-wire). Provide a wallow or shade in hot weather: pink skin SUNBURNS easily, so shade is essential. Strong rooting behaviour means rotate ground or expect tilled paddocks. Allow ample space; sows need a clean, protected farrowing area with a creep/rails to reduce piglet crushing.
Diet
Omnivore fed a balanced grain-based ration (corn/barley/wheat with a protein source such as soybean meal) formulated to life stage; pasture, vegetables and suitable food scraps can supplement. Lactating and growing pigs need higher protein/energy. Provide constant fresh water (a large sow drinks many litres daily). Avoid overfeeding mature/pet pigs to prevent obesity, and follow local rules banning meat/swill feeding.
Behavior & temperament
Generally docile, intelligent and manageable, though large size demands respectful handling, especially around farrowing sows. Purpose: DUAL but principally a MATERNAL breed for lean bacon/pork — exceptional for large litters, abundant milk, good mothering and longevity, which is why it underpins most commercial F1 hybrid sow lines. Boars also used as terminal sires for lean growth.
Health
Robust and adaptable. Key concerns: sunburn and heat stress in the unpigmented white skin (provide shade/wallows); leg and foot/joint soundness under heavy weight; standard swine diseases (respiratory PRRS/mycoplasma, parasites). Some white-pig lines historically carried the stress/halothane (PSE) gene — reputable seedstock is now largely stress-negative. Watch sow body condition and piglet crushing at farrowing.
Tips, DIY & hacks
Always provide shade and a wallow/mud or sunscreen on ears and back in summer. Use farrowing rails/creep areas and heat lamps for piglets. Keep bedding dry and rotate paddocks to manage rooting and parasites. Trim/condition feet and don't let breeding stock get over-fat. Choose stress-negative (halothane-free) genetics. Excellent first 'serious' breeding pig due to docility and easy farrowing.
