In an independent study, pigs in a US piggery were fed GM corn and soy from weaning until slaughter.[i]
The GM-fed pigs had 2.6 times the rate of severe stomach inflammation of pigs fed a non-GM diet.
The uteruses of pigs fed GM were 25% heavier than those fed non-GM.
Farmers report increased need for antibiotics, high levels of livestock deaths, listlessness and aggression in animals fed GM.[ii]
