Chapter 1

Butchering in Build 42

A dead animal is not food. It is a job. Butchering is the skill that turns it into meat, leather, bones and more.

The Butchering skill raises cut quality. Higher levels give better meat and more of it. XP comes from butchering animals, removing animal parts, and filleting fish.

Meat

Venison, beef, pork, lamb, rabbit, chicken. The reason you started.

Hides

Big animals give them only on the hook. They become leather for clothes, bags and the forge bellows.

Bones and sinew

Tools, needles, bone armor and thread.

Heads

The brain inside tans the hide. Keep every head.

The butcher's loop

Get a bodyHunt, trap, or cull the herd.
Hang itBig animals go on the hook.
DrainBlood into a container.
SkinThe hide comes off.
CutMeat, then the head.
BonesThe skeleton drops. Collect it.

Why it matters

One deer done right feeds you for days and gives leather for a season. The same deer done wrong gives 2 scraps and a rotten pile.

Chapter 2

Build your butcher

Butchering is slow to train because it needs animals. A head start saves a lot of deer.

Rancher (job)

+3 Butchering and +4 Animal Care. Raise them and cut them. The natural pick.

Chef (job)

+2 Butchering and +4 Cooking. The kitchen butcher.

Hunter (trait, 8 points)

+1 Butchering plus Tracking, Sneaking, Aiming and Short Blade. The field butcher.

Fast Learner (trait)

130% XP in every skill except Fitness and Strength.

Watch out: Keen Cook gives only +1

The Keen Cook trait gives +2 Cooking and only +1 Butchering. Its free recipes are all for the kitchen.

Watch out: point costs change

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

Butchering is a normal skill with 5 books at 3, 5, 8, 12 and 16 times XP. Volume IV is called Master Butcher's Complete Guide.

Chapter 3

Knives and the hook

You need a blade with an edge, and for big animals, a hook to hang them on.

Knives

Hunting knife, kitchen knife, meat cleaver. The usual tools.
Stone knife or forged blade. Crafted knives work fine.
The blade must not be broken. Small animals and fish also need a blade that is not dull. Sharpen it first.

Build a Butcher Hook

Find it in the Build menu. Place it outdoors or in a shed, out of sight of any livestock. It can never be moved once built.

NeedCarpentry 3, 2 planks, 2 nails, 1 large hook, a hammer (not a club hammer)

You getThe hook, plus 30 Carpentry XP

Watch out: where you put it is forever

Near the freezer. Away from the pen. Away from where you sleep. Blood and rot are not bedroom decor.

Secret: the large hook

Large hooks come from garages, warehouses and mechanic shops. Blacksmiths can forge one. Find it before you find your first deer.

Chapter 4

Small animals: no hook needed

Rabbits, birds, squirrels, rats, frogs and chickens are butchered by hand.

Butcher a small animal

Put the dead animal in your inventory with a sharp knife. Right-click it and butcher, or open the Crafting menu and use the small-animal butcher recipe on a surface.

NeedA sharp knife

You getMeat, feet, a head, feathers or a hide, and Butchering XP

Animal	Typical result
Chicken	1 whole chicken, 1 head, 2 feet, and a pile of feathers
Rabbit	Rabbit meat, a small hide and a head. Bones from the skeleton after.
Small bird	Small bird meat
Rat or mouse	1 skinned rat or mouse

Secret: rabbits give hides by hand

Rabbits do not fit on the hook, and they do not need it. Butcher a rabbit by hand and you still get a small hide. Keep it for rabbit leather.

Secret: feathers are pillows

Chicken feathers stuff sewn pillows. 1 pillow takes 100. Keep them.

Chapter 5

Big animals: the hook, step by step

Deer, cows, pigs and sheep go on the hook. Each step is its own action with its own reward.

Hang the animal

Carry the body to the hook. Right-click the empty hook and add the corpse. The animal now hangs.

Good to knowA deer is heavy. Park a car next to the hook and unload straight from the trunk.

Drain the blood

Right-click the hanging animal. Drain blood into a bucket or bowl. A sheep gives 8 liters or more.

Take the hide

Harvest the leather. You get an unprocessed hide. This is the step the ground can never do.

Take the meat

Harvest the meat. This is where Butchering skill matters most. Higher skill, better cuts, more of them.

XPRoughly in line with how much meat you get

Take the head

Harvest the head. Later, extract the brain from it for brain tan. Heads stay fresh 5 days and rot after 7. A rotten head gives no brain.

Collect the skeleton

The stripped skeleton drops to the ground. Right-click it and collect bones. You get animal bones. The sinew came off with the meat.

Watch out: the context menu sometimes does nothing

A known Build 42 friction. If right-clicking the corpse gives no butcher option, check that you carry a knife. For small animals, open the Crafting panel and run the recipe from there.

Chapter 6

What each animal gives

Every animal drops a different mix. The counts change with size, genetics, skill, freshness and whether you used a hook.

Animal	Meat	Hide size	Extras
Deer	Venison	Medium (adults)	Sinew, bones, head
Cow	Beef, the most of any animal	Large	Lots of blood, bones, head
Pig	Pork	Medium	Bones, head
Sheep	Lamb	Medium	Sinew, bones, head
Rabbit	Rabbit meat	Small	Bones, skull, head
Chicken	Whole chicken	None	Feathers, feet, head
Baby animals	Less meat	Small	Same as the parent, smaller

Watch out: yields feel small at first

Players are often shocked that a whole cow gives modest meat at level 0. The number rises with Butchering skill. It also drops hard for roadkill and ground butchering. This is by design.

Chapter 7

Meat quality and cut quality

Two things decide what ends up in your freezer: how the animal died, and how good you are with a knife.

Factor	Effect on meat
Your Butchering level	Better cut quality every level. More usable meat.
Butcher hook	More meat than the ground, plus the hide.
How it died	Shot or slaughtered is best. Roadkill is far worse.
How fresh	A fresh body gives fresh meat. A rotten body gives rotten meat.
Animal genetics	Some animals have a better meat ratio. Breed for it.
Animal size	Bigger and older gives more. Babies give little.

Secret: Angus for meat

Among cows, Angus is the meat breed. Holstein is the milk breed. Pick the herd for the job.

Yield estimator

A rough guess, built from the rules above. The game does not publish its exact formula.

Chapter 8

Bones, sinew, blood and heads

The parts most players throw away are the parts that start whole crafting chains.

Animal bones

Bone needles, bone hooks, bone tools and bone armor. Carving turns them into things.

Sinew

Tough animal thread. Bigger animals give more. It becomes sinew thread for Tailoring and binding tools.

Blood

Drained into a container. Players report you can drink it. Its crafting uses are still few.

Heads

Extract the brain. 1 brain plus water makes 1 Bowl of Brain Tan. That tans exactly 1 hide.

Secret: 1 animal tans 1 hide

Every animal gives exactly the brain its own hide needs. Never throw away a head until the hide is tanned.

Chapter 9

Hides and the leather chain

An unprocessed hide rots. Leather does not. 4 stations get you from one to the other.

Softening BeamRemove flesh. Remove fur, or keep it.
Brain tan1 brain plus 300 ml water.
Tannin BarrelSoak the hide.
Drying rack7 days in mild weather.

Rack size	For
Small	Rabbits, raccoons, baby animals
Medium	Adult sheep and pigs, and de-furred deer leather
Large	Cows, and furred adult deer leather

Watch out: fur or no fur is decided once

You can only remove fur before tanning. Most leather recipes take either kind. Some, like the Large Bellows for the forge, want crude, un-furred leather. Check the recipe first.

Secret: cut big leather into small

1 large leather becomes 2 medium. 1 medium becomes 2 small. A cow hide covers any recipe. The full chain is in the Hunting guide.

Chapter 10

Fish: filleting

Fish are butchered too, and it counts for Butchering XP.

Slice a fillet

Right-click an uncut fish with a sharp knife. Slice fillets. Bigger fish give more.

NeedA sharp knife

You getFish fillets and Butchering XP

Secret: the safest Butchering XP in the game

You do not need a cow to start. Fish on a quiet riverbank, fillet them at home. A few fish a day is steady, zero-risk Butchering XP.

Chapter 11

Rot, roadkill and waste

The clock and the car are the two ways to ruin a carcass.

The rot clock

A dead animal changes stage about every 50 hours on default settings: fresh, then rotten, then a bloody skeleton, then bones, then gone. Rotten bodies give rotten meat. Butcher the same day.

Roadkill

Hitting an animal with a car kills it, but the body is marked as roadkill. Roadkill gives far less meat. It also damages the car. Early Build 42 let players farm deer with trucks. That was patched.

Watch out: the kill stresses the herd

Killing an animal inside its pen stresses every animal in that pen. Lead it out first. Butcher out of sight.

Secret: the composter takes leftovers

Rotten meat and scraps go in the composter. Nothing is wasted.

Chapter 12

Training plan: 0 to 10

XP scales with meat. More meat, more XP. So skill, the hook and fresh bodies all feed the grind.

Levels 0 to 3: fish and rabbits

Read Butchering I. Fillet every fish. Butcher every trapped rabbit. Cheap, safe and daily.

Levels 3 to 6: the hook

Read II and III. Build the hook. Hunt deer or cull spare farm animals. Do every step on the hook: blood, hide, meat, head, bones. Each is an action. All but the blood give XP.

Levels 6 to 10: the herd

Read IV and V. A breeding herd is an endless supply. Cull the extra males. Big, fresh animals on the hook give the most meat and the most XP.

Secret: parts count

Removing parts gives XP too. Bones, sinew, and heads on the hook. Do the whole job, every time.

Level by level: Butchering

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

Level	Do this for most of your XP	Why
0 to 1	Read Butchering I. Fillet every fish	Zero-risk daily XP
1 to 2	Butcher every trapped rabbit and bird	Small animals, small steady XP
2 to 3	Build the hook. Hang a deer, do every step	Hide, meat, head, bones: 4 XP steps
3 to 4	Read Butchering II. A deer a week on the hook	Fresh big animals pay most
4 to 5	Cull spare farm animals out of sight	Ranch surplus becomes XP
5 to 6	Read Butchering III. Cows on the hook	The most meat, the most XP
6 to 7	Rabbits by hand too, for small hides	Extra hides, steady XP
7 to 8	Read Butchering IV. Breed a herd for the block	Endless supply
8 to 9	Weekly slaughter day, full process	Routine
9 to 10	Read Butchering V. Keep the herd cycling	Same day butchering, never rotten

Tips, tricks and fixes

20 tips from the block

Setup

Take Rancher or Chef for a head start.

Build the hook next to the freezer, away from the pen.
Keep 2 sharp knives. Sharpen them.
Read the book before a slaughter day.

At the hook

Butcher the same day the animal died.
Never butcher roadkill and expect much.

How sure are we?

Every fact here was checked in September 2026. We checked the game files for version 42.21.0. Order of trust: the official wiki, then well-sourced fan guides, then player reports.

Skill effects, XP sources, hook versus ground, roadkill penalty, leather chain and rack sizes. Confirmed on the official wiki.
Exact yields. The wiki says counts depend on size, genetics, skill, freshness, roadkill and the hook. No fixed numbers are promised here.
Chicken results. From a fan guide cross-checked against the wiki.
Blood uses. Player reports only.
The context menu bug. A fan guide's report.
Job values. May change.
Checked against the game files (42.21.0): job and trait bonuses, the hook recipe, which animals fit the hook, yield rules, XP per step, blood amounts, head rot and the leather chain.
