They are also able to discriminate between familiar individuals, and among humans. Cattle can tell the difference between familiar and unfamiliar animals of the same species (conspecifics). Studies show they behave less aggressively toward familiar individuals when they are forming a new group.  Calves can also discriminate between humans based on previous experience, as shown by approaching those who handled them positively and avoiding those who handled them aversively.  Although cattle can discriminate between humans by their faces alone, they also use other cues such as the color of clothes when these are available. 
First of all, I think that this kind of debate is great–exactly what we need in a culture where quality of food and health is mostly ignored. My family are cattle ranchers in South Dakota, breeding meat cattle, not dairy, but the conditions are mostly the same. Not bad, but not ideal. As a nutritionist, I also know that milk and most dairy is not digestible by most people in the world, the exception being those with northern european ancestors. Millk does have naturally occuring hormones as well as naturally occurring opiates. Like anything else, there are more nutrients in raw, unpasteurized milk. If you are going to feed it to your children or drink it yourself, lets support farmers who are working for a better and cleaner world. Support local. Then organic and lets get farming back to the way it used to be–sustainable both for family farmers and for the earth.
