Chapter 1

Animals in Build 42

Build 42 added real animals. They eat, drink, get scared, have babies and grow old. Look after them and they feed you forever.

Animal Care is the skill for living animals. It is not Butchering, which is for dead ones, and not Tracking, which is for wild ones. Higher Animal Care shows you more about each animal, gives more milk, wool and eggs, and stops stressed animals breaking away while you work on them.

🐄

Cows

Milk and lots of meat. The biggest pen.

🐑

Sheep

Wool and meat. Some milk.

🐔

Chickens

Eggs and quick meat. Need a hutch.

🐖

Pigs

Meat. Eat almost anything.

🐇

Rabbits

Small meat and hides. Breed fast. Come from traps.

🦃

Turkeys

Eggs and meat.

The ranch loop

  1. FenceMake a livestock zone.
  2. StockTroughs, water, hutch.
  3. CatchRope, carry, or trailer.
  4. CareFeed, water, pet, clean.
  5. HarvestMilk, wool, eggs, dung.
  6. BreedKeep the herd going.

Why it matters

A cow is a fridge that refills itself. A hen is an egg every day. Once the shops are empty, the pen is the pantry.

Chapter 2

Build your rancher

Animal Care levels slowly. Every daily chore gives a little XP. The Rancher job skips most of the grind.

Rancher (job, 0 points)

+4 Animal Care, +3 Butchering, +1 Fitness. Knows how to make barbed wire. The livestock job. It shipped as Livestock Farmer and was renamed in 42.13.

Farmer (job)

+1 Animal Care. Mostly a crop job.

Fast Learner (trait)

130% XP. Good because chores give small amounts.

Watch out: point costs change

The game makers still tune traits and jobs. Always read the numbers on your own character screen.

Books and tapes

Animal Care is a normal skill with 5 books at 3, 5, 8, 12 and 16 times XP. Level 3-4 is called Animal Welfare Basics. 2 VHS tapes, A Day on the Farm and The Petting Zoo, give +75 each for your first 3 levels.

Secret: Carpentry 3 is the real requirement

Troughs, hutches and butcher hooks are Carpentry 3 builds. A rancher with no carpentry has nowhere to put the animals. See the Carpentry guide.

Chapter 3

The animals

Each animal has breeds, and each breed is good at one thing.

AnimalGivesNeedsGood to know
Cow and bullMilk, beef, a large hide, dungThe biggest pen, about 80 tiles for an adultHolstein for milk, Angus for meat, Simmental in between. A cow only gives milk after she has had a calf.
Sheep and ramWool, lamb, a medium hide, milkShears for woolRambouillet is reported as the wool breed.
ChickenEggs, meat, feathersA hutch to lay and roost inThe only animal at risk from the night predator sandbox option without shelter. Sandbox: Night Predator
Pig and boarPork, a medium hideA penEats almost anything.
RabbitMeat, a small hideA small penTrapped rabbits become tame when picked up. See the Trapping guide.
TurkeyEggs, meatA penToms can be aggressive when stressed.

Watch out: deer cannot be kept

Deer are always wild. You can fence one in, but it stays wild and does not eat or breed. Hunt them instead.

Secret: males fight back

Bulls, rams, cockerels and toms attack when stressed. They can knock you down. Do not corner a stressed male.

Chapter 4

The livestock zone

A livestock zone is a patch of ground you tell the game is "home". Animals stay inside it. Everything they need must be inside it too.

1

Fence an area

Build or find fences all the way around. Gates are fine. Bigger is better. Small stock needs about 20 tiles. An adult cow needs about 80.

2

Mark the zone

Right-click inside the fence and create a livestock zone. Drag it to cover the whole pen. Zones that touch join into one big zone.

3

Put everything inside

Troughs, water, hutch and shelter must be inside the zone lines. A trough one tile outside is invisible to the animals.

Watch out: the trough outside the line

This is the number 1 ranch mistake. The animals starve next to a full trough because it sits just past the zone edge. Check the zone overlay.

Watch out: too small

A cramped pen means stress, slow growth and less milk. Overcrowding shows up as a stress reason when you inspect the animal.

Chapter 5

Food, water and shelter

3 daily needs. Miss any one of them and the animals leave, sicken or die.

🌾

Food

Fill a feeding trough with grass cuttings, hay, vegetables, fruit or animal feed. Big animals also graze grass tiles inside the zone.

💧

Water

A water trough. Fill it from a container, or let rain fill it. Sources disagree on whether animals drink from puddles, so give them a trough and be sure.

🏠

Shelter

A roofed part of the pen. Animals use it in bad weather. Chickens need a hutch. Walls help. The roof matters more.

Watch out: one trough, one job

A trough holds food or water, not both. To switch, empty it first. The game will tell you the container must be clear.

Watch out: unloaded animals still need you

Animals far from any player still get hungry and thirsty over time. Sandbox: Animal Stats While Away A long trip away can come home to a dead herd. The sandbox has a setting to slow that down.

Secret: cut grass with a scythe

Grass cuttings are free feed. A scythe or a sickle on grass tiles fills a trough for nothing.

Chapter 6

Catching and moving animals

Farm animals are found on farms around the map. Getting them home is the hard part.

Rope and lead

Attach a rope to a large animal and it follows you. Good for short walks.

Carry

Small animals like chickens and rabbits can be picked up and carried. Picking up a wild rabbit tames it.

Animal trailer

Hitch a livestock trailer to a car. Load the animals. Drive. The way to move a herd across the map.

Watch out: catch them before the pen is ready

An animal with no zone, no trough and no water is an animal you are about to lose. Build the pen first. Then go shopping.

Secret: farms are where the animals are

Farm pens around the map already hold cows, sheep, pigs and chickens. Many farms also have troughs you can take.

Chapter 7

Stress and trust

Every animal has a stress score and a trust score. Low stress and high trust mean more of everything.

What stresses animals

  • Zombies nearby
  • Loud noise. Gunshots and running inside the pen
  • Overcrowding
  • Dead bodies nearby, including butchering in sight of the herd
  • Hunger and thirst

Stressed animals give less, may fight, and may leave the zone. Inspect an animal and it tells you why it is stressed.

Trust, called Acceptance

A hidden score of how much the animal trusts you. Pet it once a day. Trust rises. Higher Animal Care builds trust faster. High trust means less stress and fewer escapes.

Secret: the inspect window

Right-click any animal and choose Info. It shows type, breed, sex, age, health, stress, trust, zone, and whether it is ready to milk or shear. Higher Animal Care reveals more, including health genes.

Watch out: never butcher at the pen gate

Slaughter in view of the herd spikes stress. Do it out of sight.

Chapter 8

Milk, wool and eggs

The daily harvest. This is where Animal Care XP comes from.

1

Milk a cow or ewe

Bring a bucket. Right-click the animal and milk it. Only females who have recently given birth produce milk.

NeedA bucket and a mother animal
Higher skillMore milk, and less chance she breaks away mid-milking
2

Shear a sheep

Bring shears. Right-click a sheep with grown wool. Electric shears are faster.

You getWool for Tailoring, and Animal Care XP
3

Collect eggs

Right-click the hutch and get eggs. Hens lay in the hutch. Leave some eggs in the hutch to hatch chicks.

4

Collect dung

Animals leave droppings. Pick them up with gloves or a shovel. They go in the composter for fertilizer. Leaving them makes the pen unhealthy.

Secret: milk becomes butter and cheese

A butter churn turns milk into butter. Milk can be processed further with the right recipes. A dairy cow feeds the kitchen for months.

Chapter 9

Breeding

A herd that breeds never runs out. A herd that breeds too much eats you out of feed.

  • You need 1 male and 1 female of the same species, both adults, in the same zone.
  • Cows breed all year. Some animals have a season.
  • Babies must stay in their mother's zone to drink milk.
  • Every animal has genes for milk, life span, strength and more. Breed the best to the best.
  • Inbreeding over generations weakens the herd. Bring in fresh animals now and then.

Watch out: 2 bulls, 1 pen

More than one adult male in a zone causes trouble. Keep spare males in a separate pen, or in the freezer.

Watch out: overbreeding

Every new animal needs food, water, space and cleaning. Let the herd grow only as fast as your feed does.

Chapter 10

Sick animals and the hutch

Dirty pens make sick animals. Clean pens make healthy ones.

  • Clean the hutch regularly with water and a cloth. A filthy hutch kills chickens.
  • Pick up dung so the pen stays healthy.
  • Watch the health line in the Info window. Falling health means hunger, thirst, cold or filth.
  • Animals cannot catch the Knox Infection. Zombies do not attack them by default. But animal noise can pull zombies to your fence.

Secret: the predator option

Custom Sandbox has a night predator option. If it is on, chickens without a hutch can vanish overnight. The hutch is their shield.

Chapter 11

From pen to plate

Eventually an animal becomes dinner. Do it right and you get meat, a hide and bones.

  1. Lead the animal out of sight of the herd.
  2. Kill it and carry it to a butcher hook.
  3. Hang it. Drain blood, take the hide, take the meat, take the head.
  4. The hide goes to the leather chain. See the Hunting guide.

Secret: Rancher starts with Butchering 3

The job that raises the animals is also good at butchering them. Everything else is in the Butchering guide.

Chapter 12

Training plan: 0 to 10

XP comes from chores: milking, shearing, giving water, petting and collecting eggs. More animals means more chores means more XP.

1

Levels 0 to 3: chickens and tapes

Read Animal Care I. Watch both VHS tapes. Start with chickens. A hutch, a trough, and daily eggs and petting. Cheap, small, and every day is XP.

2

Levels 3 to 6: a dairy cow

Read II and III. Get a cow and a bull. Once she calves, milk her daily. Pet everything. Water everything.

3

Levels 6 to 10: the full ranch

Read IV and V. Sheep for wool, pigs for meat. Breed for good genes. A big herd is a big daily chore list, and that is the point.

Secret: petting is free XP

Pet every animal every day. It builds trust and gives XP. It costs nothing.

Level by level: Animal Care

The best single thing to do at each level. Read the matching book first when one exists.

How sure are we?

Every fact here was checked in September 2026 for game version 42.20.4. Order of trust: the official wiki, then well-sourced fan guides, then player reports.

  • What the skill does and how XP is earned. Confirmed on the official wiki.
  • Pen sizes. "About 20 to 80 tiles" from a fan guide for 42.19.
  • Puddles. One source says animals drink from puddles, another says only troughs. The guide says use a trough.
  • Breed specialties. The wool breed is player-reported. Cow breeds are on the official wiki.
  • Job values. Rancher's +4 Animal Care and +3 Butchering from a guide citing the wiki's 42.18 page. May change.
