These reports from farmers and seed dealers can easily be dismissed as
anecdotal evidence from which no conclusions can be drawn.

Indeed. And that will remain the case unless anecdotes are followed up
by scientific studies of the matter.

E.g. Shawn S. Donkin, Ph.D. Animal Sciences Department, Purdue
University, fed corn/cornsilage to 16 dairy cows. 8 cows were fed
from Bt corn, and 8 from a near isogenic line of non Bt corn.

Average dry matter intake was 52.7 and 55.9 lb/d, for Bt and non-Bt
respectivley (SE=1.12, p=0.06), average milk yield was 84.2 and 86.9
lb/d, (SE=1.20, p=0.15). Curiously the author concludes that his
results show no differences.

And have you emailed them to ask why? Or are you just going to let
your aspersions stand?
