Anyway to see which animals need to graze or what food they need in general?

Game starts you off with rooster, donkey, cats, dogs, yaks, etc.

Pretty sure not everything needs to graze in a pasture. How do I know what does and doesn't need what type of food?

Mostly this follows the real-life animals. If it needs grass on a farm, it probably needs grass in game. If you are not sure about a particular animal, the Dwarf Fortress wiki should let you find out.

Pigs are great, don't need light or grace outside. For birds the Turkeys.
