One more question regarding cattle, I'm not sure what food modern cattle are fed but i'd like to know if cattle can survive on only grass, hay and silage etc, or do modern cattle breeds require grain and more calorific food to maintain their condition?

i think cattle can survive on grass, hay and silage alone, its when they are brought into cattle sheds for the winter that they are then fed on grain etc.
