Cattle are not designed to eat grains. When they do it alters the ph balance in their digestive system and allows infections such as e coli to occur (which is why they have to feed anti-bio-tics to cattle in feed lot operations and only discontinue 5 days before slaughter - which is not a long enough period for all of the drugs to dissipate)
