Based on my observations over the years, I actually think that it is an appetite/needs thing.
I recall commenting that to my wife one fine spring day - after watching them turned out for the first time onto pasture. One cow was munching along happily on grass when she deliberately reached out of her way to chow down on a big, healthy dandelion.
There's an education to be had in watching cows' grazing patterns. We all know that they have their preferred species of forage. I have seen them clean off the dandelions to the nubbins when there is soft grass right next to the "weed".
In another observation just this summer, I sat and watched the cows and bull graze over a very small patch of regrowth connecting 2 paddocks - maybe 30' wide and about 50' long - which had grown grass and a variety of fairly mature weeds, like lambsquarter and ragweed.
Some of the cows nosed right past some of those weeds after quite noticably taking a sniff at them, while others reached right for them.
What was particularly amusing was to watch the bull ambling slowly thru the stretch after the cows, cleaning off everything they left behind!
