From the feed they eat and how it gets digested in their bodies.
Fat = energy, and energy means increase in weight gain or body condition in cattle. High energy in feeds is good for fattening cattle up for slaughter, or getting thin cows to put on weight.
Potential energy in the form of methane.
The grazing of cattle is the act of forage consumption by the cattle. Cattle, and other ungulates, are very effecient at converting solar and chemical energy into a valuable, useful product.
Because outdoors cattle will burn off the energy that is used for meat production. If they are kept indoors they will have more energy to use for the conversion of feed into meat.
Cattle grazing or grazing cattle is when cattle are set out on a piece of land (within a fenced area, mind) and eat the grass and legumes that grow there for a period of time.

One advantage of a cattle farm is that by producing beef, people have a way to tap otherwise unusable energy, vitamins and minerals.
The three fodder plants are: Berseem, oats, sudan grass. These plants are used as food by cattle. These provide energy required for doing farm work to cattle.

Yes they can. Canola meal is a by-product moderately-high in energy and an excellent source of protein for cattle, and is a good feedstuff to incorporate into your animal's feeding program if protein is lacking. Canola itself is very high in energy (due to the oil content), so it should be fed to cattle in modest amounts, just like you would with any type of high-energy grain.
Domesticate cattle will live in barns, or on pasture. Wild Cattle will take residence in woody
In a grazing system, only 20% of the energy cattle get from eating grass are used for maintenance, mobility, growth and reproduction. The other 80% is expelled as waste through sweat, respiration, urine and feces. But this 80% energy isn't wasted either: it gets incorporated back into the soil to be reused and recycled by the grasses that the cattle have eaten.
