how when cows and horses etc are in a field the grass doesn’t just…go

Question

On train home and I see cows in a field chomping, and the grass is very short, but how come they don’t eat all the grass and ruin the field?

What made me think this is locusts or whatever they’re called which destroy crops and leave nothing behind

Farmers often rotate their cattle between different fields to manage grazing pressure and allow the grass in each field to recover. This rotational grazing helps maintain the health of the pasture by giving the grass time to regrow and preventing overgrazing.
