Brahmin

Brahmin are mutated brahman cattle with two heads. In the real world, Brahman are a kind of cow named after the priestly caste of India. When the bombs fell, cows mutated and grew two heads, and were given the name Brahmin. They also have 8 stomach compartments, twice as many as normal cows.

Biology
The brahmin are quite hardy. They are also a delicious toasty brown, as you'll notice in the picture to the right. They attack by head-butting or trying to gore someone with their horns, so brahmin-tippers beware. For some reason, only the left-most brahmin head has horns.

Though harder to kill with bullets than people, one dart from the Dart Gun kills a Brahmin.



Mad Brahmin
"Mad Brahmin" are believed to be either a Brahmin with a pre-war disease known as "Mad Cow Disease", or simply a Brahmin that has suffered brain degeneration to the point of hostility. Little is known about the condition, or why Brahmin would become aggressive. They are sometimes sighted among inexplicably rotting corpses of other Brahmin, suggesting some form of disease in the herd. Mad Brahmin are aggressively hostile except to those with the Animal Friend perk. Encounters of Mad Brahmin have commonly been reported near the entrance to Vault 101, Jury Street Metro Station, and Farragut West Metro Station, though Mad Brahmin could possibly be found all over the Capital Wasteland as a random encounter. Though Mad Brahmin may be hostile, they are not deadly. Mad Brahmin can be outran and due to their two heads, are prone to headshots.
 * If killed, they give 1 xp and you get Brahmin Steak from the corpse.

Function
Brahmin serve a vital environmental niche in Fallout - they form the foundation of survival for many species in Fallout, most notably, humans. They also form the backbone of the NCR economy. They also form the backbone of the New Reno "NCR brahmin rustling" economy. Brahmin can pull carts, old cars, plows, and dead bodies. Brahmin can be driven into herds then used as stampedes on rival tribal villages. Brahmin can be worshipped. Brahmin hair can be woven into bags and ropes. Brahmin hide can be stretched over wooden or metal rods to make canoes, if you're into that sort of thing. Brahmin sinew can be used for bowstrings or thread for stitching. Brahmin droppings is great fertilizer (and fuel for campfires). Brahmin meat is delicious - well, only because no one in Fallout knows what a succulent Pre-War steak used to taste like. Brahmin are a source of milk that is like modern day milk, yet terrifyingly different. Brahmin can be tipped over in Fallout 3 by going into sneak and holding A on them. Brahmin bones can be used as clubs, knives, arrowheads, eating utensils, hoes, or even dice, and their skulls look really scary dotted all over the desert landscape. Their horns can be turned into drinking horns if you feel like getting medieval. Brahmin can be used to distract a hungry deathclaw. Brahmin fat makes decent soap. Their hide can be used to make tents (or tipis/teepees), clothing, belts, saddle bags, shoes, leather armor, leather jackets, or a bizarre brahmin-looking disguise so you can sneak up on other brahmin and listen to their conversations. You can also use their tails as fly brushes or paint brushes, depending on your level of artistic talent.

There are domesticated brahmin and wild brahmin. Wild brahmin can forage for themselves, and they can be found across the wastes, gathered into small herds, wandering here and there, munching on the dirty weeds scattered throughout the desert. Fortunately for the ecology of the wasteland (and the survival of their species), brahmin can go for long periods of time without water - they don't need much to survive. They have a strong sense of smell, and they don't hesitate to stomp over any wasteland predator that threatens them or their calves - well, except deathclaws, because no one messes with deathclaws.

There are rumors that the smell of brahmin droppings is highly addictive. See Jet

Appearances in games
The brahmin appear in all Fallout games. One also appears as an easter egg in Arcanum: Of Steamworks and Magick Obscura, shown in a freakshow and described as coming from "a far away wasteland".

In Fallout 3, you can go "brahmin-tipping" by crouching and activating any Brahmin that isn't attacking you. There's no activation symbol, like when you target a door and it says "open door", but you push 'em over all the same. It uses a unique animation seen at no other point in the game, and the Brahmin moos and turns into a ragdoll for a few seconds. This is an easter egg, likely a nod to a quote from Tandi in Fallout, where she describes what there is to do in Shady Sands. She says that "brahmin-tipping gets old real quick."

Brahmin-tipping also features as a special random encounter in Fallout Tactics.
