Ah, well it seemed cogent and straightforward to me: the OP suggested that your indication that grain feeding was driven by consumer taste preference seemed to lack evidence.

It seems like something that will have been tested (certainly for low-n values), it also seems likely to vary by culture/region substantially.

One of my "if I were in charge" ideas is for origin marks that provide all information about inputs into any product made available for sale. Under sight a system one could look up whether the farmer bought grain feed.
