You have a related problem - another unnatural agricultural procedure that
was warned about: feeding meat to cattle, causing spread of BSE.

and that affects wheat prices exactly how?

BSE did impinge on beef prices

And there were fewer cattle to feed, and less money to buy grain
feed? What proportion of UK wheat is bought buy farmers? Then the
available storage silos would be getting full sooner, so the wheat
would have to go to market without waiting for a better price.
