It’s now a fairly well established agricultural practice to feed targeted probiotics to livestock as a way to both prevent and combat various intestinal bacterial infections – both ruminants and monogastric animals like pigs. Salmonella, e.coli, listeria are the usual culprits.
At least in hobby farming (which is disproportionately practiced by the gullible, it seems to me), probiotics are also given in cases of almost any kind of stress such as shipping, injury, or sickness, especially if antibiotics are being administered. I do it myself because, you know, what is the downside?
Apparently I am late to the party because recently I’ve been – harangued is not too violent a word – by several people who feel that probiotics address all sorts of human ills caused by (poor general immunity due to the feeding of antibiotics to livestock)(the host of intestinal disorders like gluten allergies etc. now so popular)(autism, ADD, cancer, leprosy).
I’m prepared to believe some of it, since there is fairly good data on animals (reducing mortality in newborn pigs, etc), but anyone have any studies on how much of it has a basis in the reality type world of human medicine?
