  Because they are hungry :). cows don’t just eat grass they also eat things they are fed by their farmers like grains, hay and corn.

  It’s an excellent source of energy and nutrients (if you have the teeeth and the digestion system for it – we don’t) and it doesn’t run away! Grass is surprising well protected though – it really grinds teeth down and it’s hard to digest.

  Cows are ruminants, which make them herbivorous (plant eating) animals. A ruminant has a stomach with four chambers designed to break down fibrous plant material that monogastrics such as humans cannot digest properly. So cows primarily eat grasses and legumes not only restricted to open fields, but also out on pastures and rangelands.
