Effect of feeding cows genetically modified maize on the bacterial community in the bovine rumen

Appl Environ Microbiol. 2007 Dec;73(24):8012-7. doi: 10.1128/AEM.01060-06. Epub 2007 Oct 12.


Rumen-cannulated cows (n = 4) were fed successively silage made from either conventional or genetically modified (GM) maize. Results revealed no effects of GM maize on the dynamics of six ruminal bacterial strains (investigated by real-time PCR) compared to the conventional maize silage.
