Cow

A cow is a common passive mob found in the Overworld. They are a source of leather, raw beef and milk.

Natural generation
4 cows spawn on grass blocks at the surface at a light level of 9 or higher with at least 2 block space above, except in Snowy Tundras, Mushroom Fields and variants.

After the world generation, they spawn individually whether or not there are cows nearby.

5% spawn as calves.

Cows can spawn inside animal pens and butchers' houses in villages.

They spawn at a light level of 7 or higher in herds of 2-3.

Drops

 * 0–2 . The maximum amount is increased by 1 per level of Looting, for a maximum of 0-5 with Looting III.
 * 1–3 ( if killed while on fire). The maximum amount is increased by 1 per level of Looting, for a maximum of 1-6 with Looting III.
 * when killed by a player or tamed wolf.

Cows can be milked by a bucket on them. Like other baby animals, killing a baby cow yields no items nor experience.

Behavior
A cow wanders around, mooing and breathing occasionally. They avoid water, lava and walking off cliffs high enough to cause fall damage. They flee for a few seconds when harmed.

A cow follows a player who holds wheat, but stops following if separated from the player by at least 8 blocks.

Breeding
If cows are given wheat, they enter love mode and pair off to create calves, granting the player a 1-7 experience orbs. The parent cows have a cooldown of 5 minutes before they can breed again. All babies obtained by breeding take 20 minutes to grow up. The growth of baby cows can be slowly accelerated using wheat; each use takes 10% off of the remaining time to grow up.

Mooshrooms
Shearing a mooshroom turns it into a cow and drops 5 mushrooms corresponding to the type of mooshroom.

Data values
Cows have entity data associated with them that contain various properties of the mob.

Trivia

 * Cows resemble Norwegian red cattle.
 * Cows in the PC Gamer Minecraft Demo are branded with a 'PCG' logo on their side.
 * Notch stated in a Tumblr post that all “breedable” peaceful mobs displayed traits of both genders and could breed with any other individual of their species. This applies to cows as they have horns and give milk (although, in some breeds, female cows also have horns).
