Why do cows graze?

Answer 1

They're big animals, bigger than humans are, so they need the water to be able to function properly. Lactating cows need more water than growing cattle or dry cows because a lot of their bodily fluids and energy are being put into milk production, which gets taken out of their body regularly when being suckled by a calf or milked by a machine. Cows also produce a lot of saliva to chew their cud and be able to swallow coarse plant-matter whole without choking (something we humans are incapable of doing), so plenty of water is a must. Water is also a crucial nutrient to a cow's diet, and just like if not able to eat, will die if it is not there for them to consume and use.

If you want a baseline as to how much a bovine typically drinks per day, it's typically 10% of its body weight per day. Lactating cows may drink one or two percent more, and dairy cows will always drink more water than beef cows, as far as actual volume is concerned versus percentage. Growing cattle also drink half as much as mature cows do, and bulls a little more to about the same as a dry or lactating cow.

Answer 2

If that cow is a dairy cow, and that dairy cow is lactating, she is expending a lot of water to make a lot of milk. Some cows can produce 60 kg (that's around 130 lbs) of milk per day, which means those cows need to drink a lot of water to keep from getting so dehydrated from producing so much milk. Milk is 95 percent water, and much, if not all the water that is in the body of a cow and the cow drinks goes directly to milk production, and the rest to nourish the trillions and trillions of somatic cells in her body.

Answer 3

Cattle usually drink more water when it is very hot, hotter than they can stand, and they lose a lot of moisture through their noses, the only place they can sweat from, unlike their Brahman cousins. Cattle will also drink more water if they are fed a diet that is high in salt, or a diet that is quite dry, like silage and hay, respectively.

Answer 4

They're adapted to graze; their mouths, teeth and digestive system are designed to eat and digest grass, not foliage or browse like goats are. Cows are what is called "Roughage Consumers," or, they are adapted to eat grasses that are quite coarse and don't have much nutrient to them. Browsers like goats and deer are called "Selective Consumers" because they are more picky about what they eat, when and where, unlike cows.

Answer 5

A cow needs water to keep its body hydrated.

Answer 6

Cows ONLY drink water. They do NOT drink milk, and cannot drink milk otherwise they will get quite sick with diarrhea and rumen upset.

Answer 7

using s straw.. LOL!

Answer 8

They eat grass and drink water.
