So the way I'm understanding this, you use these preventive antibiotics, or what you call class IV ionophores, and they're antibiotics we typically don't use in humans and you're doing that so the birds or the products don't get sick so you don't have to use the really important antibiotics used for human consumption. Is that right? Jean, I see you nodding your head too. Am I getting it? I'm trying to figure this out around the table. Do you have a comment?
