 Whether it's sawdust, walnut husks, corn, grains, lard, or even other cows, someone in the past 100 years has probably advocated feeding it to cows.  That's at least what I remember as one of the takeaway messages when I took ruminant nutrition and digestion.<p>So, I'm not at all surprised that he can comb through the literature and find people suggesting that cows be fed corn a very long time ago.  But it seems like a bit of a logical leap to use a few examples in the literature to refute claims like this:<p>“Before WW II, most Americans had never eaten corn-fed beef.”
