A bolus.
If you are referring to the time when a cow stands around and just chews away, this is "ball" called cud.
The technological term for the process in which a cow regurgitates its cud and chews it is called "rumination." Rumination allows cows to further break down and digest their food by re-chewing it before fully swallowing it for final digestion.
Just like in humans, molars are used to chew grass, breaking it down in smaller pieces so it can be swallowed.

Rumination.
Depends on what the cow's eating and how much it's fed.
a cow chews the grass it is eating thoroughly and slowly, so it is chewing it's cud - the masticated grass in it's mouth. - that's where the expression for long, contemplative thinking when trying to solve a problem comes from.
There is no such thing or grass species as "cow grass."
Not at all. Grass is eaten by a cow, not produced by a cow.
A saying that means that you are being pretty boring.
No. Cows EAT grass. They do not "have" grass.
Cow.
Cow's graze on grass to feed as they can easily digest grass.
