When we look at history, cows have always fed on grass and hay. They can also eat corn and cereals. Families have cows to take care of them and to bring them milk and cheese.
Nowadays, grass-fed beef can come from all over the world without you having any idea how it was grown and what it ate. The cow feeds on grass, it is always performed on the pasture so that it can graze only fresh grass. Supplements can be corn, cereals, or hay. Today, cattle are fed well to produce more milk. A cow’s stomach is different from other predators so that it can more easily deceive and survive food that is tough and rough. The cow will chew the food just to swallow it.
Unchewed food travels to the two stomachs, kidneys, and rectum. When she eats, she survives, then rests. The food also travels to the bloodstream, where her udder is located, where milk is made from it that will come out of her udder, while the rest of the cow gives strength and maintains it. And corn and cereals after their first giving gives them pounds and so the cows grow and get fat. You will reduce costs and you do not have to buy her food, you will reduce the costs of agriculture. When you feed her, you have to distribute her meals and the food does not swell so that it is easier for her to cheat. GMOs are not as good for animals as they are for humans, they should not feed on them.
Cows are specific and are different from other predators. Grass-fed beef, fed according to ancient customs, is best reared and gives you the best milk. If you only want quality and good nutrition, you have to feed her well and give her as much water as possible.
