Cattle are obligate herbivores and are built to eat roughages in the form of plants, predominantly as grasses and some forbs. They do not eat meat, and if they tried it would likely make them ill.
However, the fact that meat making them ill isn't exactly truthful. Cattle that develop a condition called "pica," which is a phosphorus deficiency, will actually eat meat, even other animals that are already dead. This is because such animals are a rich source of magnesium, phosphorus, sodium and nitrogen. Cattle with pica will also eat soil, chew wood boards and fence posts, drink others' urine, all to get those nutrients that they so desperately need if they haven't received the proper nutrition.
Normal, healthy cows won't eat meat or try to eat dead animals or the parts of dead animals like the bones and that. But, if they have some sort of deficiency that leaves them eating things like soil and wood boards, they may have tried to eat some meat too in the form of a dead animal.
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.
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.
Guinea pigs are not allowed to eat corn at all or if its sweet its really bad for them.
you got it the other way round, the corn makes the cow
Because corn is a seed and does not digest properly in our bodies as our bodies are not made to digest seeds.
For human consumption: Creamed corn (as in soup) is already broken down so it will digest easier than whole kernel corn. Processed corn such as in cereals will also digest easier than whole kernel corn. I don't know about animal consumption.
It will take an average of about 24-72 hours for a cow to fully digest their feed from mouth to anus.
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.
yes
The rumen.
Not exactly sure about corn cobs but if it's anything like corn kernels, the answer is no. most animals don't possess the quality to digest the sugars in corn.
One "cow corn" plant--more properly called field corn--plant will often have two to three ears on it.
