Cows, like all animals, do not eat water, they drink it. And cattle typically consume around 10% of their body weight in water per day.
50 tons a day
Maintenance requirements are 2.5% of a cow's body weight in dry matter ration per day.
There is no such thing as a "freshwater cow." Unless you're referring to a manatee, which can live in both fresh and salt water, in which they eat underwater plants.
Yes. Mice have a much higher metabolic rate than a cow does, which means a mouse has to eat more per body weight than a cow to keep it alive and able to move around. We have to look at how much a mouse and a cow drink on a per-body weight basis to see whether a mouse will or will not dehydrate faster than a cow will. We cannot compare how much a cow drinks or a mouse drinks per day in terms of gross volume, since these are unreliable numbers to work with. Thus, typically a mouse will drink 15% to 20% of its body weight in water per day. A cow, on the other hand, will drink 7 to 10% of her body weight in water per day. This is a huge difference, and shows that mice indeed will dehydrate faster than a cow will.
Cow's eat grass so it usually comes out green. However, it also depends on what the cow eat's. But cow's can't eat that much, just pretty much hay and grass just like horses have to eat hay and grass.
Not as a main feed source, no. But they may eat it nontheless.
Certainly not much, especially if you are going in terms of tons, not pounds (lbs). A 1000 lb cow with or without a calf will eat 25 lbs DM of forage per day. This amount changes with moisture content, so if the grass she eats has a 60% moisture content, she'll eat maybe around 40 lbs of grass per day, as fed. In terms of tons, that's 0.02 tons per day. If you were looking for a much bigger or grandioso number for how much a cow eats per day, it looks like you're plumb outta luck!
Yes. A typical lactating Jersey cow will eat 5% of her body weight per day in dry matter. In dry matter terms, a 1000 lb cow can eat upwards of 50 lbs per day. On an as-fed basis, that can range from 70 to 100 lbs per day.
Livestock are responsible for 18 per cent of the greenhouse gases which warms the world 20 times faster than carbon dioxide.
If you are feeding up this "cow" for slaughter, then it should get around 20 to 25 lbs per day, along with hay and/or grass.
For all cattle, beef or dairy, the average daily intake is 2.5% of the body weight. Lactating cows tend to eat 50% more than if they were dry. So a lactating cow would eat from 3.5% to 4% of their body weight per day.
