WHY do cows chew constantly?


The ancient ancestors of cows were absolutely defenseless,Because they could not run fast or fight back, because they did not have either fangs, claws, or developed musculoskeletal system. The ancestors of cows were apathetic, inactive and spent most of their life in a shelter. The only way to survive in this situation was the peculiar evolution of the gastrointestinal system of the animal.
The cow has a completely unusual stomach,Which consists of 5 departments: a scar, a net, a book, a rennet and an intestine. Such a stomach allowed and allows you to grab food, swallow and go so that predators do not have time to catch. And only then, in a safe place - the cows began to chew food.

By the way, cows do not have upper teeth, andUpper gum completely firm. They do not chew, but grind food with it. At this stage of grinding, the main grinding of the grassy chewing gum takes place: the cow chews it for a long time, then swallows it, and the food goes to the "book", and then to the abomasum, where the process of its assimilation takes place. Unlike the scar, the "book" can only assimilate small particles of food, and its volume does not exceed 10 liters, so the animal always feels a slight feeling of hunger, again and again grabbing grass.

Such a system helps cows to get the most nutrients from the grass, which is the basis of their diet.
