Cows are mammals. After they have given birth they have evolved, like every mammalian species, to give milk to their young. We have just "improved" the Dairy Cow so that she can give way more milk than her calf needs so we can drink it.

∙ 13y agoCows are bred and have a calf after 9 months, the calf is raised by its mother and weaned off at about 10 months of age. It is then fed a high energy roughage diet until it reaches about 800 lbs. At this time the calf will be fed a high energy grain diet (usually corn) until it reaches slaughter weight (approximately 1000lbs), then is slaughtered for meat.

∙ 11y agoAll female mammals produce milk once they have given birth to feed their young. All cows produce milk after they have given birth to a calf. Dairy cows have given birth to calves. So they produce milk. Over the years, farmers discovered that some cows produced slightly more milk than other cows. They kept those cows around along with their daughters as well as the bulls that sired them. Those bulls mated with not only the farmers cows but also with the farmer's neighbors' cows. As a result, the cows that produced the most milk became the mothers of the cows that stayed around the dairy. So the cow at the dairy produces enough milk for her calf and a whole lot more besides.

These nutrients help make and repair muscles, among other important body parts of the cow. This is what makes beef, or cow muscle that has been cut away from the cow and eaten after she has been slaughtered.

∙ 13y agoBecause they can. Seriously though, they're mammals and as females they have to produce milk for their young; it's instinctual, or rather, beyond instinctual. Without milk, baby mammals would not survive. The ability to have milk is Mother Nature's ability to create a more stronger bond between mother and young, and to ensure survival.
Dairy cows have been selected to produce milk through the man-powered process of artificial selection. Cows and daughters of cows are selected over other cows because of their better milk productivity. Bulls that sire these better-producing daughters are also kept to sire other calves from other cows to get similar results. Cows that were poor producers were culled or sold for slaughter, and bulls that only sired average or inferior calves with inferior genetics were also culled. But the heifers (and a few lucky bull calves) that showed superior genetics to their dam and sire were kept to keep improving the herd and keep producing milk. Through this process of selection, humans have developed the ideal dairy cow, from the Holstein-Freisan to the Ayrshire.

∙ 15y agoCows do not produce beef on purpose. Beef is the name for the meat of the cow. If the cow had any say, there would be no beef produced! The name for pig meat is pork, and sheep meat is mutton. Meat from calves is called veal.
