Pigs Factsheet

Pigs are the most prolific breeders in Realistic Livestock RM, with litters of up to 16 piglets. They produce no special outputs (just manure), so their value comes entirely from selling offspring. The three breeds differ significantly in price - Berkshire commands a premium while Black Pied is the budget option.

Breeds at a Glance

Breed Type Target Weight (sow / boar) Sell Value Character
Berkshire Premium 140 / 180 kg Highest Most valuable per head
Landrace Standard 165 / 205 kg Moderate Balanced mid-range
Black Pied Economy 180 / 250 kg Lowest Cheapest, heaviest boars

Boars are heavier than sows and sell for more. Berkshire pigs eat the most but command the highest prices.


Sell Prices by Breed

Pig prices peak at 24 months and stay at that level for older animals (unlike cattle which decline).

Typical Sell Prices ($)

Breed Newborn 6 mo 24 mo (peak)
Berkshire Sow 45 450 1,600
Boar 60 525 1,850
Landrace Sow 40 400 1,400
Boar 50 475 1,650
Black Pied Sow 35 375 1,200
Boar 45 450 1,500

These are typical prices for an average, healthy animal. Actual prices vary widely - well-bred healthy animals sell for significantly more, while sick or poor-quality animals can sell for far less.

What Affects Sell Price

Factor Effect
Quality genetics Better genetics -> noticeably higher price
Weight Well-fed animals near target weight are worth more
Health Healthy animals sell for significantly more
Pregnant Moderate price bonus
Castrated Moderate price bonus
Diseases Can substantially reduce price

Output

Pigs produce only manure and liquid manure - no milk, wool, or eggs. Their value is entirely in selling the animals.

Breed Manure (adult) Liquid Manure (adult)
Berkshire 50 / 55 91 / 95
Landrace 45 / 48 85 / 88
Black Pied 40 / 44 79 / 83

Food & Water by Breed

Genetics significantly affect how much each animal eats - some are naturally much more efficient than others. The Food Scale setting also adjusts consumption.

Food Consumption Range (L/day)

Breed Newborn 24 mo (adult)
Berkshire Sow 5-32 30-210
Boar 5-35 33-228
Landrace Sow 4-26 25-175
Boar 4-26 28-193
Black Pied Sow 3-21 23-161
Boar 4-26 24-168

Berkshire pigs eat the most. Black Pied are the most efficient to feed. Ranges show the span from the most efficient to the hungriest animals. Most animals eat near the middle of these ranges.

Water Consumption (L/day, newborn -> adult)

Breed Sow Boar
Berkshire 10 -> 80 13 -> 85
Landrace 8 -> 75 8 -> 80
Black Pied 6 -> 68 8 -> 72

Pregnant sows eat and drink more than usual.


Weights by Breed

Breed Birth Target Maximum
Berkshire Sow 1.6 kg 140 kg 1,050 kg
Boar 1.7 kg 180 kg 1,200 kg
Landrace Sow 1.36 kg 165 kg 1,050 kg
Boar 1.4 kg 205 kg 1,200 kg
Black Pied Sow 1.65 kg 180 kg 1,050 kg
Boar 1.75 kg 250 kg 1,200 kg

Black Pied boars have the highest target weight at 250 kg. Higher metabolism animals reach target weight faster but eat more. Castrated pigs gain weight faster than intact males.


Reproduction

Parameter Value
Sow breeding age 6+ months
Boar breeding age 8+ months
Boar max breeding age 48 months (4 years)
Sow fertility ends 96 months (8 years)
Gestation 4 months
Min health to breed 75%

See the Breeding Reference for a side-by-side table of breeding ages, gestation, and litter sizes across all species.

Key insight: Boars retire from breeding at just 4 years while sows can breed until 8 years. Plan your boar replacements early!

Litter Sizes

Pig litters are the largest of any animal - typically around 12 piglets, and up to 16 from a highly fertile sow.

Outcome Likelihood
~12 piglets (typical) Most likely
Smaller litter Uncommon
Up to 16 piglets Possible with high fertility

Litter size is driven by the sow's fertility genetics, not her age. What changes with age is her chance of conceiving each cycle, which stays high through the prime years and tapers to zero by 96 months. A sow must be at 75% health or above to conceive.


Lifespan & Death

Event Age
Boar stops breeding 48 months (4 years)
Sow stops breeding 96 months (8 years)
Old age deaths begin 180 months (15 years)
Maximum lifespan ~240 months (20 years)

Death can be toggled off in settings. Accidents can happen at any age (affected by weather).


Diseases

Disease Spread Fatal? Treatment Impact
Foot & Mouth Moderately Yes Slow, moderate cost Major price loss
PED Moderately Yes, devastating to newborns Quick, affordable Severe diarrhoea (liquid manure drastically increased, solid manure severely reduced)

PED warning: Porcine Epidemic Diarrhoea is extremely fatal in newborn piglets. In a large herd, a PED outbreak can wipe out an entire generation of offspring. Older pigs rarely catch PED on their own, but any pig infected during an outbreak is in danger - treat quickly. See the Disease Guide.


Tips

  1. Breeding is the business model. With litters of around 12 piglets (up to 16) and a 4-month gestation plus recovery time, a healthy sow can produce a litter roughly every 7 months. Sell the excess for profit.

  2. Replace boars early. Boars stop breeding at just 4 years - half the sow's fertile period. Buy young boars regularly or use artificial insemination.

  3. Berkshire for profit, Black Pied for volume. Berkshire piglets sell for noticeably more but eat more. Black Pied are cheaper to maintain for large-scale operations.

  4. Watch for PED. A single PED outbreak in a pen full of newborn piglets can kill most of them. Isolating young piglets or disabling diseases in settings can protect your investment.

  5. Pen capacity matters. If a pen is full when piglets are born, the excess are automatically sold. Make sure you have room for those 11-16 piglet litters.
