Actually, it's not the cow that directly uses the energy from the corn she is fed, but rather it's the microbes in her rumen that have access to it first. Microbes use the energy--in the form of starch, which is made up of carbohydrate--for growth and reproduction and to convert carbohydrates into volatile fatty acids, three of which are proprionate, acetate and butyrate. Proprionate is the most sought-after VFA for beef and dairy production as it is what helps an animal meet its energy requirements. By-pass starch, which gets digested in the abomasum and reabsorbed in the small intestine, is also used for energy by the cow.
Such VFAs and by-pass starch are used by the cow for maintenance, growth, production (such as producing milk [dairy cows] or meat [beef cattle]), and reproduction in that order. Excess energy is converted and stored into fat, such which is often seen in feedlot cattle when they are fed an 85 percent ration of grain which may be or include corn. Dairy cows will readily convert the energy they get from corn into milk, and use that energy for meeting reproductive requirements: this also applies to beef cows.
Energy from corn is used in meeting maintenance requirements (rebuild/repair muscle/skin/fat tissue, homeostasis, cell function, metabolic rate, etc.), reproductive needs (milk, normal reproductive function, normal estrous cycles [or for males, normal sperm growth, seminal fluid, and libido]), growth (in growing animals, and growing muscle, bone, fat, skin, etc.), normal body functions (eating, defecating, urinating, moving around, socializing with other cows, awareness of surroundings, etc.), and many other things.

Would you receive more energy from corn by eating it directly by eating the same mass of of beef from a cow that had been fed corn?
You would get more energy from eating the corn directly. In general, only about 10% of the energy gets passed up the food chain which means that you only get 10% of the energy that was originally contained in the corn by eating the cow that ate the corn.

Would you receive more energy from eating a cow that consumed corn by eating it directly or by eating the corn?
Eating the cow will give you plenty of protein and other nutrients found in meat that corn does not provide.
Why does a farmer use cow dung?
They use this cow dung that contains methane in it to make energy.
How does cow make corn?
you got it the other way round, the corn makes the cow
If a cow gets into a corn field how do you find out how much of the corn the cow destroyed?
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.
How many ears on cow corn?
One "cow corn" plant--more properly called field corn--plant will often have two to three ears on it.
How do you prepare Cow Corn for eating?
ok.. what is cow corn? I have made corn for decades... Can we assume field corn? For cattle, we let it dry before collecting. Around 12% is awesome. For humans, we do not eat field corn.
Is a composition of fish meal and corn grain good for a cow?
No. Leave out the fish meal because it has a potential risk of containing prions that can make a cow sick with BSE. Corn itself is merely a starch, an energy source, and doesn't provide much nutrition. You're better off using corn as a supplement and utilizing good quality hay and/or pasture as a main food source for your cow. If a protein source is needed, use canola or soybean meal or something similar that is high in protein content.
Would you receive more energy from corn by eating it direcly or by eating the same mass of beef from a cow that had been fed on corn?
The latter. Corn eaten as a meal, be it corn-on-the-cob or as a side-dish, can only give a person (human) so much energy and nutrients; basically it mostly acts as a gut-filler and not much else. We can get some protein and energy from it, but it doesn't stay in the stomach and get digested as thoroughly as meat does. Energy from meat is released slowly over time as the amino acid enzymes in the stomach break down the meat, giving us a long-term burn of energy to use. Corn or any fruit and vegetable, only acts as a quick-burst of energy, then decreases as soon as it came.
Do you need to grind corn to feed a cow?
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.
What is cow corn?
"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.
