Event MON 810 Representative performance of Bt corn hybrids, events 176 (KnockOut[TM]), and BT11 (YieldGard[TM]) (K. Ostlie, Minnesota, 1996).
2
Safety thoroughly evaluated Cry 1 Ab protein has been evaluated and tests confirm that the protein: –Has a long history of safe use on food products, spanning almost four decades by organic farmers and home gardeners –Is present at very low levels in grain –Is rapidly degraded (in seconds) when exposed to simulated gastric fluids –Shows no similarity to known allergens –Shows no harmful effects to animals when fed at very high levels

Feeding Trials In two separate published studies, chickens fed Bt corn showed no differences in growth and feed efficiency compared to chickens fed conventional corn (Allrich, et al, 1998), (Halle et al., 1998). A lactating dairy cow study found no differences in feed intake, milk yield, milk composition, or udder health between cows feed Bt or conventional green chop (Faust and Miller, 1997, Iowa State Univ.). No differences reported in performance in the first year of a two-year study involving beef cows grazing on Bt corn or conventional corn stalks (Russell and Peterson, 1999, Iowa State Univ.). No differences reported in digestibility in sheep fed Bt or conventional silage (Daenicke et al, 1999).
