I actually came from a sheep grazing family, living on the land in Central 
Queensland, North of Longreach.  Our stock were free range, grassfed, what 
ever you choose to call it.  However, once purchased and trucked, awaiting 
slaughter at city feedlots, stock are grain fed. ALL MEAT IS!!  But, I 
don't know how long the holding periods are, and if this would actually 
invalidate Paleo meat, as such.

Sincerely

Dot Spence
