The feed it eats (grass, hay, grain, silage). Grain and silage is higher in energy (in the form of fats) than other feed sources.
Energy for the cow initially comes from the plants she eats and digests.
Energy is passed from cow to cow through the food chain. Cows consume plants as their primary energy source. When one cow eats plants, it metabolizes the energy from the plants, which then gets transferred to other cows that might consume that cow as food. This flow of energy from one cow to another is known as the transfer of energy through trophic levels in a food chain.
Typically a lactating cow will eat 50% more than a dry cow would. As for energy needs, a lactating cow needs around 15% more energy than dry cows do.
There are many energy efficient cells working in the energy conservation in a cow. These include sleeping an extra amount to digest food.

Depending on her body condition, if she is thin, she will probably eat 1 or 2% more than usual during the winter to keep her energy levels up in order to keep her lean, thin body warm enough in the cold. However, if she has adequate fat cover on her, her daily intake won't change; if she's overly fat, her daily intake will decrease because she won't need as much energy intake to keep her warm. But since Jerseys are dairy cows and putting fat on them is much harder than a beef cow like a Hereford, my first answer still stands.
Weight is determined by the balance between energy intake and energy expenditure. When energy intake exceeds expenditure, the excess energy is stored as fat, leading to weight gain. On the other hand, if energy expenditure exceeds intake, the body uses stored energy reserves, resulting in weight loss. Maintaining a balance between energy intake and expenditure is crucial for weight management.
A diet that is high in salt will cause a cow to intake water a lot more than a cow on a normal low-salt diet. Just like in humans, if a cow drinks a lot of water, she will urinate a lot. Cows don't get diabetes, so it's more to do with higher liquid intake than anything.

Approximately 60 percent of your daily caloric intake should come from carbohydrates, which are your body's primary source of energy. It is important to choose complex carbohydrates like whole grains, fruits and vegetables for sustained energy levels and overall health.
Food chains give a simplifed view of the flow of energy because, for example if the grass eats fertilizer and a cow comes and eats that patch of grass and then humans come and we eat the cow the the energy from the fertilizer, the grass, and the cow all go into us because it was pasted down to the organisms that were part of that food chain. Hope it makes sence. :)
An example of a food chain with a human would be: grass (producer) -> cow (primary consumer) -> human (secondary consumer). In this chain, the human consumes the meat of the cow as a source of energy and nutrients.
