No, but it does make it easier for the microbes in the cow's rumen to break down and digest. Processed corn--corn which is rolled, ground or crushed--breaks the lignin comprising the skin of the corn kernel and breaks the protein matrix surrounding the starch granules. All of this make the nutrients in the kernel much easier for the ruminal bacteria to access, break down and use for their own nutritive needs before it goes to the cow.
There's no need to feed a cow corn throughout the winter. Good hay is good enough to feed her: it's cheaper, less trouble and better for her to eat. Corn should only be fed if she's losing condition or the hay you are giving her is really low quality.
"Cow Corn" or animal feed is simply corn that is harvested later than sweet corn. "Cow Corn" is then dried and used for animal feed, or used in ethanol. Field corn is a far less sweet for of corn and is not the same as sweet corn. It has more carbohydrates and is grown differently. Most corn will grow only one ear per stalk. Newer hybrids of field corn can grow two or three ears per stalk. It has a far drier taste then sweet corn.
You cannot make a cow. Feed is to be fed to a cow, not to make one.
Usually it's called "field corn." It's a cultivar of corn grown predominantly for livestock feed, but also for ethanol production.
It is if it's processed enough that the microbes in the cow's rumen can break it down and digest it. It would be a waste of money to feed if it's fed whole/unprocessed and not much nutrient can be gleaned from it by either the microbes or the cow.
Often, yes. Grinding or milling--or even rolling--exposes the starch granules and breaks the protein matrix in the starch component of the corn grain making it much easier for the rumen microbes to digest and obtain nutrients from. However, grinding corn too fine can reduce palatability and chewing time, and thus reduce its effectivity as a good high-energy feed source.

It depends on the class and breed of animals you are referring to, and the availability of corn to a producer. Some producers will have no corn in the feed for cattle, others will have 85% corn in the ration for their animals (particularly if they're feedlot cattle). Dairy cows, which are lactating, will typically have around 10 to 30 percent corn (or a little more) in their formulated ration.
you got it the other way round, the corn makes the cow
Sweet corn is soft from the day it blooms. "Cow" corn is hard it's entire lifespan. Corn feed is a better way of stating it. Hard corn "corn feed" is also packaged as popcorn. Just a little better cleaning.
Guinea pigs are not allowed to eat corn at all or if its sweet its really bad for them.
It's not that easy to take account how much corn the cow ate, other than going into the corn field, finding the tracks and tracking the cow from the point where she entered the field to the point where she came out--or were forced out.
