What do farm animals eat?

In order to help us understand the kinds of foods eaten by farm animals, we were given a selection of different foodstuffs in labelled jars from one of our parents.  There was silage, hay, barley and many more.  We passed them round and had a look at them.  Some of the more brave amongst us had a sniff too.  Some of them smelled quite nice, but there were others that we didn't really like the smell of!
