Outcome depends on the type of food it takes right ? So if a cow consumes Genetically modified grass rather than normal will the quality of milk increase? And can we observe any changes in the behaviour ?
One of the elements influencing the sensory qualities of milk and meat products is the kind of forages consumed by ruminants. The impact of the type of forages (corn silage, grass-based forages), the conservation strategy (hay versus silage), and the botanical composition of the grass on the sensory qualities of cheeses (colour, texture, flavour) are discussed for dairy products. There is no scientific evidence that genetically modified feed has an effect on milk output or composition. It is crucial to remember that cows consuming GM food do not modify an animal's (or a person's) DNA. Cow's milk has no GMOs. A contrast may be made to diabetics who use insulin; the individual does not become GMO. A dairy contrast is that a cow given chocolate does not produce the milk that comes from that animal.

La soia ed il mais sono i componenti base dell'alimentazione delle bovine da latte, questi due componenti sono nella maggioranza dei casi derivanti da OGM, non si sono mai riscontrate differenze tra animali alimentati con o senza OGM
