No, I don’t think you’re trying to make the same point. Synthetic hormones in mass quantities are not the same as trace amounts of natural hormones. Do you not see the difference?
Cows are herbivores, not cannibals. Grains are a part of their normal diet. Body parts from other cows are not part of their normal diet.
Now, if you can just prove that synthetic bST is different from natural bST and that mass quantities of synthetic hormones are ending up in the finished product vs. trace amounts of natural occurring hormones, you'll really be on to something.

I thought the FDA established a ban on the use of most animal protein in feed for cattle back in 1997. Maybe I'm not remembering correctly but I didn't think this was an issue anymore - at least with domestic production.
