Subject matter is what an art work has been created about. For example if you were to have a painting of a cow, then the subject matter is a cow.
Plant matter.
What's the matter with that doggone cow? She ate a whole bag of Puppy Chow.
The egg hatches in a matter of hours, and a chicken-cow hybrid emerges from the broken shell.
Maintenance requirements are 2.5% of a cow's body weight in dry matter ration per day.
It should only be a matter of a couple hours.
Impossible thing to accomplish. Cows don't talk nor will ever talk, no matter what other species of animal (including humans) are crossed with a cow to get a "talking cow."
A dairy cow would die a matter of a few weeks before she even gets to the point where she is deemed "feral." I would see a beef cow becoming feral, yes, but not a dairy cow.
There are many functions and structures in a cows anus. This is to help the animal to excrete waste.
A cow that has a calf at side and suckles that calf, no matter if it's her own or foster calves.
No, a cow is an herbivore, which means it primarily feeds on plants rather than decaying organic matter like detrivores do. Detrivores are organisms that feed on dead and decaying plant and animal material.
Nothing. Milk is milk no matter what cow it comes from. Don't get suckered in the BS that "strawberry-flavoured" milk comes from red cows, or "chocolate" milk comes from brown cows, etc. etc. Milk is the same colour, flavour and often consistency no matter the colour, breed or type of cow it comes from.
