Anyone care to give me a quick explanation of the various types of hay/straw that are available...when I go to buy some they usually ask me whjat kind I want, and I usually punt and say 2nd cut, but not really sure what the significance of the various types are...the prices does vary so I am sure there is a reason.

Also, hay versus straw? Is straw just hay w/out seeds? Can you use either as a feed for animals?
