During short time studies the effects of feeding genetically modified plants to several animal species were investigated. However, till now there are no long term studies on the use of genetically modified feedstuffs in dairy cow feeding. The present study was realized over a 25 month period (almost 2 lactations) with a total of 36 dairy cows (supplemented by outgoing cows). Apart from the feed composition, zootechnical and metabolic parameters, animal health and fertility data were evaluated. No specific effect was identified when comparing the ration containing transgenic corn products with the non-transgenic basic line.
