Breeding is a game mechanic that allows fed animals of the same species to breed with each other to make new animals.[2] Animals (except Wolves and Cats) will follow a player holding Wheat if the player looks at the mob, and will continue following the player until it is out of range, fed wheat, or until the player stops holding wheat. They may only breed once per wheat given, as long as they are not following their offspring. As of September 15th, 2012 breeding is not a game mechanic present in the Xbox edition of Minecraft.
Mechanics
Pigs, Sheep, Chickens, Cows and Mooshrooms enter "love mode" if fed one wheat (as of Snapshot 12w36a, Pigs are only responsive to Carrots, Chickens to wheat seeds, with Cows and Sheep still breeding with Wheat). Wolves enter love mode when they are fed any type of meat. Cats enter love mode when they are fed a raw fish. Tamed wolves and cats must be at full health before being fed to enter "love mode". Animals in "love mode" emit hearts constantly and will path towards nearby animals of the same species that are also in love mode.[3] The two animals will "kiss" for about two and a half seconds, and then a baby animal of the same species spawns either in between the parents or on the same blocks as the parent that was spawned first, which ends love mode for the parents. They will not be able to enter love mode again for 5 minutes. However, they can be herded with the appropriate material, regardless of age. After the baby animal has spawned, it will follow its parents for 20 minutes before growing to full size.
One item per parent is needed to breed a single baby. When sheep are born, they will be the color of one of their parents (See:Wool Dyes). Sheared sheep will continue to produce babies of their original color.
Animals are uninterested in wheat lying on the ground. Using wheat to breed animals that give food (cows, mooshrooms, pigs, chickens) is a way of getting more efficient food than bread.
Villagers will breed of their own accord depending on the available houses, or at least "registered doors". (See the NPC Village page for full details.) When they breed, they will produce a smaller villager but unlike other baby animals (excluding kittens,) they don't have big heads. Baby villagers will run around the village and will "play" tag. This is also when baby animals started following their parents (although their parents followed them long before then.)
Ranching
Animals in an open setting may be difficult to breed. It may be easier to construct fences for animals to stay. Even a medium size pasture can result in animals neglecting to notice one another in love mode. Animals will spawn in the same square as their parent. It should be noted, however, that if they are in the same square as a fence, glass pane, or other item that takes up only part of a square, offspring may spawn in or on the other side of the block.
Pigs, Chickens, Cows, and Mooshrooms can all provide food when killed. This food will be cooked if they are killed with fire. Cows additionally drop leather, and Chickens drop feathers. Sheep drop one wool when killed, but it is more productive to shear them as they drop 1-3 wool. One dye can be used to color their wool before shearing or breeding, which is more efficient than dying the single wool after killing. Dyed sheep produce offspring of their current color; if the two sheep are different colors, the color of the baby sheep will match one of the parents, chosen at random. Chicken Eggs can be harvested from Chicken farms, and can be used in addition to chicken breeding to speed population growth, as they have a 1/8th chance of producing a baby chicken when thrown. Cows can be milked with a bucket, and Mooshrooms can be 'milked' for Mushroom Stew using a bowl. Mooshrooms can also be sheared for 3-5 Red Mushrooms, although this will turn them into normal Cows.
Example of the fence gates and pressure plate entrance.
Sometimes when farming animals, it may be difficult to keep all animals in the farm, yet still allow you to get in and out of the farm. A simple way to keep your animals in is to dig holes. Dig a hole outside of the farm about 3 blocks deep. Place ladders as needed. Dig up once under the farm. Place more ladders. Since Pigs, Cows, and Sheep are more than one block wide, they will not fit in the hole resulting in them running in circles trying to get in the hole. It should be noted that baby animals and Chickens can fit in a one block hole. An alternative to this is fill the hole in the farm with water. Since all mobs float, they will not be able to escape. A simple, yet effective, way of creating an entrance/exit to a pasture is the use of two Fence Gates and a Pressure Plate. You open one gate and as you pass over the pressure plate, it opens the other gate. The "off" signal made by the pressure plate returning up will close both gates. The whole event is quick enough to thwart any possible pathing out by the animals. Be warned though, keeping the animals away from the entrance is a good practice, otherwise just one getting onto the pressure plate could trigger a "stampede". Another method is to place two blocks in place of a fence and put a trap door on the bottom part of the higher block. Animal AIs cannot make paths that use trapdoors and they cannot open them. This is easier than most other methods and takes up little space (2X2X1).
Automated animal farms and mass breeding
A large pasture for manual mass breeding.
Small scale automated breeding systems can be built by herding passive mobs into moving minecarts and summoning them to a central breeding location - this has the disadvantage of still breeding new mobs relatively slowly (one every five minutes.) Also, when saving and loading the game the mobs will "escape" from the minecarts - this can be dealt with by "storing" them inside of glass blocks.
Mass animal breeding farms can be built by "compressing" mobs into a very small number of squares using a mob compression system. Mobs are crushed into a small area (Generally a three high 3x3 chamber) - these animals can be used to produce new animals that will remain trapped inside the enclosure and can be bred themselves - meaning that extreme amounts of animals will eventually be stored in the same square and can be fed simply by "spamming" stacks of wheat into the enclosure. If starting with two mobs and feeding them for an hour while using this system (assuming no missed feedings or killed mobs) 17 adults and 24 baby mobs will be held inside the 3x3 cell. After two hours this would increase to 247 adults and 361 offspring.
Chickens can be fed through a slab in the side of the enclosure or from above through a hole in the top center, other mobs can also be fed through a 1 wide hole in the side of the enclosure without any risk that they will escape. Feeding the same number of mobs as slain while harvesting is enough to keep mobs at roughly their current level.
When breeding chickens or other animals in a fenced-in pen (with a fence gate) and you get a large amount of them, it can be difficult to leave the pen without a chicken escaping before you close the fence gate. A way to deal with this is to go to the opposite side of the pen as the door / gate, pull out some wheat, wait until the chickens crowd around you, then putting the wheat away by switching items and quickly running to the gate. The chickens will not be fast enough to get to the other side of the pen when you do.
Baby animals
Baby animals are smaller variations of their parents, having small bodies, relatively big heads, higher pitched sounds, and faster walking speeds. They do not drop resources or experience, primarily to balance the breeding. While baby cows and mooshroom calves can be milked, only adult animals will drop food resources. Baby animals grow into full sized animals after twenty minutes, which is one day in Minecraft (Except sheep - they can grow faster if they eat grass). Dogs (tame wolves) have another variation: the puppy does not gain its full health automatically (even when it grows to full size), but must be fed to increase its HP.
Baby animals, when born, will follow their parents until it has grown in to an adult. Tame dogs and cats will follow their owner if the parent is absent or sitting.

History
Breeding is a game mechanic first introduced in Beta 1.9 Pre-release 2.
During the early developments of Breeding, Notch tweeted: "You know what would be fun? If every single animal in minecraft came from eggs. Breeding would involve moving egg blocks around."[4]
On the 9th of September 2011, xDerik tweeted "Can you confirm or deny animal breeding in 1.8?" to which Jeb replied "It's pushed to 1.9."[5]
In Beta 1.9 Pre-Release 3, Notch added baby animals, the offspring of Pigs, Sheep, Chickens, Cows, and Mooshrooms; since Beta 1.9 Pre-release 3, the following mobs: pigs, sheep, chickens, cows,and mooshrooms enter "love mode" when fed with wheat. When breeding was introduced in the Beta 1.9 Pre-release 2, all sheep were born with white wool, irrespective of their parentage, but when Beta 1.9 Pre-release 6 came out, baby sheep can be either of their parents' colours, even if they were dyed. Animals are uninterested in wheat lying on the ground.
Before 1.0, if a Snow Golem was bred, it would start attacking other Snow Golems.
During Beta 1.9 no baby animals spawned and adult animals did. They could also breed instantly after "giving birth". This resulted in "spam breeding" allowing for over one hundred animals in a cage only big enough for two.
In Snapshot 12w03a, wolves can be bred with any type of meat.
In Snapshot 12w04a, cats (tamed ocelots) can be bred with raw fish.
In Snapshot 12w08a, villager children and kittens are the only baby mobs that have a head the right size for the body.
In Snapshot 12w36a, Pigs are responsive to Carrots, Chickens to wheat seeds, with Cows still breeding with Wheat.

Bugs
- Animals in love mode need to be able to see each other to breed, but they don't have to be close to each other: for example, sheep in two different pens separated by multiple fences can breed if they are both in love mode and have seen each other.
- Animals occasionally disappear in multiplayer even if they are enclosed.
Trivia
- Before the full release, Snow Golems also had the ability to enter "love mode" when fed wheat. If two Snow Golems were in love mode, they would fire snowballs at each other, causing them to step out of love mode and flee from each other.
- Animals of the same species are able to breed with each other regardless of whether or not they are a parent to the animal they are bred with.
- A baby animal will follow you if you are holding wheat, but the wheat cannot be fed to it.
- Baby wolves seem to be naturally attracted to the player.
- Baby Wolves will attack mobs just like adults.
- Baby Cats and Villager children do not have big heads like other baby mobs.
- Squids are the only passive mob that cannot be bred.
- It's not yet possible to farm animals in the Xbox version of Minecraft, as they despawn, no matter if they're fenced in, so that means dyeing sheep would only be good for however many days it takes before the sheep despawns, usually in one game day.
