I think she just used telekinesis to milk the cows utters'. I think Spike was referring to the fact that he never saw her with the ability to do that before then. It might be a special form of spell, I don't know, but I think it was her using advanced telekinesis like she performed on Fluttershy in Green Isn't Your Color. That's just my guess, though.
