Landrace

Sus scrofa domesticus · also called American Landrace, Danish Landrace, Large White-eared (historical)

⚖️ Compare
Landrace

A white, very long-bodied breed developed in Denmark for bacon production, the Landrace is distinguished by large, forward-drooping ears and exceptional sow productivity and milking ability. It is a cornerstone maternal breed in commercial crossbreeding programs worldwide.

Habitat & space requirements

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 stage
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.

Color & pattern variants

Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.

Selectively bred (man-made)
American Landrace

American Landrace

U.S. strain developed from Danish imports plus other Landrace bloodlines; selected as a maternal/crossbreeding line with excellent litter size and milking.

Danish Landrace

Danish Landrace

The original Danish bacon-type strain bred for long carcasses and lean meat; foundation for most national Landrace populations.

British Landrace

British Landrace

UK strain developed from Swedish/Danish imports, used as a prolific maternal breed in British pig production.

Habitat & enclosure

Suited to pasture-plus-shelter or well-bedded barn housing. Provide a dry, draft-free building or hut with deep straw, sturdy hog-panel or electric fencing, and a wallow plus shade outdoors — the white coat and pink skin sunburn easily. Allow ample farrowing space; the long body and heavy milking sows benefit from roomy, clean, well-bedded farrowing areas with anti-crush rails.

Diet

Feed a complete grain-based ration matched to stage (higher protein ~16-18% for growing/lactating animals). Lactating sows have high energy and water demands due to large litters and heavy milk output — provide abundant clean water and free-choice minerals. They use pasture and forage but are typically grain-finished for lean bacon-type carcasses.

Behavior & temperament

Docile and manageable, selected primarily as a maternal line. Purpose is bacon/lean meat production and, critically, prolific mothering: sows farrow large litters (often 10-12+), milk heavily, and raise pigs well, which is why Landrace genetics underpin most commercial F1 sows. Generally calm but sows can be protective at farrowing.

Health

The very long back and heavy productivity can predispose to leg and structural weakness and shoulder/foot lameness; select for sound feet and legs. Pink skin sunburns readily. Some historic Landrace lines carried the stress (halothane/PSS) gene causing porcine stress syndrome and pale-soft-exudative meat — buy stress-negative tested stock. The large pendulous ears can limit forward vision.

Tips, DIY & hacks

Provide deep bedding and good footing to protect the long back and legs. Shade and wallows are essential for the white coat. For breeding, source halothane-gene-negative, registered stock and select hard for leg soundness and teat number to exploit the breed's maternal strengths. Note many countries maintain their own Landrace strains (Danish, American, British, Dutch) that differ slightly.
