An [[ambusher]] armed with a [[crossbow]] and a [[quiver]] full of [[bolts]] can and will attack these animals, cautiously approaching them ("ambushing", their speed and chances of not being noticed being dependent on their skill) before opening fire at their query with crossbow bolts. Hunting is a very outdoorsy activity, and will take your hunters well past where you can establish reasonable defenses; in addition hunters will occasionally do stupid things that will get them maimed, such as hunting [[lion]]s, or worse still, killed in grisly ways, such as attacking [[elephant]] families. |

Hunting makes an erratic but, when done by a skilled ambusher, very worthy meat source. It takes the bother of pasturing animals away, but comes at the trade off of defensibility. Many players on mature fortresses are simply too concerned with enemy sieges and the like to send dwarves out too far, and will thus disable hunting jobs on their dwarves. | Hunting makes an erratic but, when done by a skilled ambusher, very worthy meat source.

You can increase your chances of catching something by baiting the trap. |

Any dwarves sent out to create and arm traps in the animals' midst will scare them away or (worse) trigger their aggression. As such most of the animals that you will end up caging will be small [[vermin]], which cannot be turned into meat and, besides low-value pets, cannot be turned into anything particularly useful, except for the few that can be processed into extracts - see below. |
− | To successfully trap large animals you need to build choke points into your map. The destruction of ramps to create sheer cliffs is the easiest way to force them to go down a particular route; with the construction of walls, ponds, channels, and so forth, you can force them to walk right through your cage traps. | + | To successfully trap large animals you need to build choke points into your map. The destruction of ramps to create sheer cliffs is the easiest way to force them to go down a particular route; with the construction of walls, ponds, channels, and so forth, you can force them to walk right through your cage traps. This is additionally interesting for defense, which is probably your primary goal: anything that will funnel animals will funnel invaders too, and caged goblins make good target practice once [[mass pitting|pitted]]. |
Leave a small gap one or two tiles wide (depending on how many of the critters you want to trap) and build your cage traps there. If the animals haven't moved off or been scared off by the time you're done, and they're docile enough to not attack once they see your dwarves, use military orders to send a dwarf (or several) around behind the animals and herd them toward the choke point. | Leave a small gap one or two tiles wide (depending on how many of the critters you want to trap) and build your cage traps there.

=== Breeding === | === Breeding === | ||
− | + | When a male and a female of the same species are present on the map, sooner or later the male will impregnate the female. Animal reproduction requires absolutely no contact between them, and in fact will occur regardless of distance, physical obstacles such as walls or locked doors, number of each gender, and even ownership. This has been jokingly refereed to by players as spore-based breeding; even a male in a herd of wild animals outside the fortress walls can impregnate a female locked deep in the lowest level, and females can get pregnant again immediately after giving birth (much like dwarves). The only thing that has been reported to prevent pregnancy is caging, but females that are already pregnant can give birth while caged (also much like dwarves). | |
− | Using [[cage trap|cage traps]] judiciously (or taking advantage of the animals [[elf|elves]] trade) can sometimes snag you a breeding pair of wild animals. These can be used to establish crazy schemes, like [[alligator]] farms and [[giant eagle]] [[egg production|hatcheries]]. Tame something unusual and start something crazy if you get lucky enough! | + | Some [[immigrant]]s will bring [[pet]]s or stray animals with them, often to the effect of forming or completing breeding pairs. Remember that you only ever need one male: the only non-butchering product male animals produce, besides reproduction, is [[wool]], and only a few of them. For this reason having one male bull and ten female cows is a good idea. |

There is currently a per type population cap, currently observed to be around 50, past which animals will not get pregnant; existing pregnancies will mature to term, and once some adults are slaughtered, the population can begin moving up again. | There is currently a per type population cap, currently observed to be around 50, past which animals will not get pregnant; existing pregnancies will mature to term, and once some adults are slaughtered, the population can begin moving up again. | ||

Tame animals with the [GRAZER:<value>] token (most herbivores) need to constantly munch on grass to survive, and as such require a [[pasture]] containing [[grass]], [[cave moss]], or [[floor fungus]] to graze upon, or they will starve to death. [[Elephant]]s and [[rhinoceros]]es in particular are bugged at the moment; they cannot eat fast enough to keep up with their grazing needs, and as such will slowly starve to death if tamed. | Tame animals with the [GRAZER:<value>] token (most herbivores) need to constantly munch on grass to survive, and as such require a [[pasture]] containing [[grass]], [[cave moss]], or [[floor fungus]] to graze upon, or they will starve to death.

Designate a grassy area as a pasture [[activity zone]] ({{k|i}}-{{k|n}}), set ({{k|N}}) the animals to be released onto the pasture, and your dwarves will haul the designated animals to it - this does not require any specific labor, and much like harvesting food, will be performed by all dwarves, even those with all hauling jobs disabled. Once in the pasture, the animals will munch on all the grass they need, as long as there is enough of it. |
Pastures can be easily depleted if the herd of animals on it is large enough; in addition, having too many animals on a pasture at once will lead to fights, which can seriously maim and injure your livestock. Since an above-ground pasture requires a significant plot of land, it is a major security concern - having enough grazing land for your animals while also keeping them protected from invading goblins is an important concern. A solution is to use the fact that livestock can graze on [[floor fungus]] and the like as easily as on regular old grass, and wall off a pasture inside of a [[cavern]] layer or set them loose in your underground [[tree farm]]. | Pastures can be easily depleted if the herd of animals on it is large enough; in addition, having too many animals on a pasture at once will lead to fights, which can seriously maim and injure your livestock.

− | + | Animals on [[restraint|restraints]] still can [[path]] (1 tile in any direction from the chain/rope), and that can hurt your [[Maximizing framerate|framerate]]. By making a series of 1x1 rooms with doors set to "non-pet-passable", and restraining the animals there, the animals have nowhere to go and so [[path|pathing]] is not a problem. The door keeps them from wandering; the restraint is necessary to get them into the room in the first place. (see [[restraint]] for proper removal technique.) [[Activity zone#Pit/Pond|Pits]] can also be adapted for this purpose, without the restraint and with multiple animals. | |
− | + | The pens idea would be a good idea if pets actually understood non-pet-passable during calculation of paths. Instead they believe they can get through during mental calculations. Cold, hard, reality stops them at the door, but they continue to path as if they could get through, so, they just stand there (until a dwarf comes by and opens the door, at which point they gleefully run past). Pets in cages helps framerate the most, followed closely by restraints, since the search space bottoms out after only 2 moves (corner to corner). Pits, with no access besides (raised) bridges and (closed) floodgates, are also very effective, as pathing will stop as soon as the space of the pit is exhausted, so it's like a restraint with a slightly longer leash. Pens using floodgates would work, although loading the pets in would be nigh impossible without dropping them in from above, as anything in the way of a closing floodgate stops it from closing. It would be quite extreme, but such a collection of 1x1 pits could be an effective way of stopping pathfinding while retaining breeding. One could even use bars instead of floodgates, and have a really proper zoo/cage. | |
A common strategy is to cage all your young until matured because they do not give the same amount of bones, meat, and fat as adults. Some tamed wild species take more than 1 year to mature, unlike most domestic animals; this makes it excusable to butcher, for instance, elephant calves right away, as they take ten years to mature. | A common strategy is to cage all your young until matured because they do not give the same amount of bones, meat, and fat as adults.

− | Once | + | Once an animal has been killed (be it by slaughtering or hunting) you only have a limited amount of time to butcher the corpse before it rots. If your butcher is distracted by other tasks it is quite possible to lose the foodstuffs, so make sure to keep a number of [[butcher]]s ready. An animal corpse or body part is available if it is taken to the butcher's shop or in a refuse stockpile within a certain distance of the shop; it is not available if it is merely lying around, so a corpse stockpile near your butcher's shop may be necessary. The skill of the butcher only affects the time taken for the butcher animal task, not the amount produced, nor the quality. |
− | + | To keep your animal population growing you should preferably butcher the males except for one of each species you are breeding, because one male is enough to impregnate all the females. The number of males does not affect how frequently the females give birth as long as you have at least one (which can also be a pet). | |
− | Meat and fat goes to your food stockpile. Bones, horns, hoofs, hair, cartilage and raw hides go to the refuse stockpile. Cartilage has no use and should be disposed of, but you would be well put to create custom stockpiles for hides next to your tanner's shop (see [[#Tanning|''Tanning'' below]]), for bones/horns/hoofs next to your craftsdwarves workshop (see [[#Bone carving|''Bone carving'' below]]), and changing the settings on your main refuse pile to not accept bones, horns/hoofs and hides.

If it takes too long for the butchered parts to be hauled into the stockpile, the food will rot and miasma spread. To prevent this, it is advisable to build the butcher's workshop outside of the fortress, near refuse piles (you may want it inside the walls though). The fresh air prevents miasma spreading. Miasma doesn't spread through diagonal openings, so a clever architect might isolate the smell in a 3x3 room with the shop. | If it takes too long for the butchered parts to be hauled into the stockpile, the food will rot and miasma spread.
