Equids here are any remotely horse looking four legged creature. That includes things like cattle, deer, camels and whatnot. This is just a few basic things on those creatures. Feel free to look up more information.

First off is the standard horse.

The horse part of this page was modified from this site for your use and I only edited parts I felt might be off, still the owners get all the credit! :

Some of you will be absolutley insulted by this page, but I can't help feeling that if a select few of you knew a little more about horses that you might play the game better. This is very basic stuff - if you don't know it then you should! Please email me if you spot any mistakes or do not agree with what I've said.

Heights
I say this time and time again but some people just don't take it in. Horses heights are measured in hands and there are four inches in a hand. Heights go as follows: 13hh, 13.1hh, 13.2hh, 14hh, 14.1hh, 14.2hh, 14.3hh, 15hh, 15.1hh, 15.2hh, 15.3hh, 16hh, 16.1hh... You get the picture. Horses are technically 'horses', not 'ponies' at the height of 14.2hh. Please make sure that the height you say your character is is. This is a helpful page for learning about the breed of horse that you play. However, be aware that some 'breeds' listed there aren't really breeds (like Palomino and Mustang).

Colors
You also need to make sure that your colour is found in the breed that you play (no black Suffolk Punches!). Also, there is no such thing as huckleberry bey! I'm tired of horses joining saying that they're this colour! Huckleberry Bey was an arabian stud - now you know! The main colours? Hmmm... (I'm not going into detail with 'brindle' and 'brown' and stuff...)

Genders
Once again, very basic. Some people insist that a mare is a 3+ female horse, others a 5+. Here, fillies and colts will become mares and stallions at 3 years old.

Stallion [An uncastrated male horse over 3 years of age]
Mare [A female horse over 3 years of age]
Colt [A male horse under 3 years]
Filly [A female horse under 3 years]
Foal [Either a colt or filly]
Weanling [A young horse who has been weaned. A horse can be weaned at around a month old if necessary.]
Yearling [A one-year-old horse]
Gelding [A castrated/neutered male horse]
Stag [A now castrated adult stud that once produced foals] 
Sire [The father of a horse]
Dam [The mother of a horse]

Parts
Withers these are the shoulders of the animal.
Flanks are right in front of the hips and behind the belly of the animal, they are a soft spot.
Coup this is the hindquarters of the animal.
Hock is part of the leg. The 'fetlock' is on the front, and it's the part right above the hoof that is the ankle of the animal.
Poll is the area between the ears of any animal.

The bovine part of this page vaguely discusses both domenstic cattle and other bovines such as gazelle.

Heights
Measured in hands or feet, doesn't matter in particular for this game.

Colors
Colors are extremely variable for domentic animals (it's a sign of their domenstication). Wild beasts rarely have shifts in colors, for instance Brindled Gnu or Wildebeest all have the same general coloration - dull grayish black (though their beards may be black or white depending on where they are from).

Look up your breed/species to determine a suitable color.

Genders
Generally, bovines are all called by the same gender names listed below.

Bull (sometimes Buck) [An uncastrated male bovine over 3 years of age]
Cow [A female bovine over 3 years of age]
Heifer [A female that has never been bred]
Calf [A baby bovine]
Weanling [A young bovine who has been weaned.]
Yearling [A one-year-old bovine] 
Steer [A castrated/neutered male bovine]
Sire [The father of a bovine]
Dam [The mother of a bovine]

Parts are the same as with a horse, except bovines commonly have horns (recessive) or are polled (without horns, dominant trait) and do not shed these horns at all in their lifetime. Sometimes wild bovine females do not have horns.

Bovine Example:
Brindled Gnu or Wildebeest-
Length: 6 to 7 feet
Height: 4 to 5 feet
Weight: 350 to 500 pounds
The male gnu's head, with its curved horns, looks like a bull's head. But it's tail and mane make you think of a horse. It looks different from either because it has a large beard that makes it look like an old man. It can run up to 50 miles per hour, a newborn gnu can stand and run when it's only 5 minutes old.

Also check out the Common Eland, Hartebeest, or Impala for wild bovine examples.

Camels and Llamas:
There are four related members in the camel family. The llama and alpaca are domensticated, the guanaco and vicuna are wild camels.
There are two kinds of camel, the Arabian or dromedary with 1 hump and the Bactrian camel of Asia with 2 humps. Other than the giraffe, the Arabian camel is the tallest land animal. (Elephants and Arabian camels can be the same height.)

Deer:
Deer males (and sometimes females) often grow antlers. These are shed and regrow yearly and branch out into forks instead of being straight or curved like horns are.

Deer males are usually called Bucks, but otherwise gender names are mostly the same. However, moose males are called Bulls, so you'll just have to do your research for your species to be sure you're not making a fool of yourself. ~_^

Some species are the Mule Deer, White-Tailed Deer, Moose, Elk, Reindeer, ect. (those are all pural and singular form. It's not 'Elks' or 'Meeses' or 'Deers'.)

 

Eh, hope it's been helpful!
