"No cow gives milk unless she gets pregnant and gives birth to a calf. (I remember one dairy farmer I visited insisting that the cow would be in pain unless she was milked; true, but only because she had just given birth to a calf who was no longer present.) The milk is meant for the calf. … But our greed is greater than any reasonable person could expect: we do not allow the calf even the small amount he or she would normally take in a day. We want it all. So the calf is separated from the cow immediately upon birth. The industry says this must happen instantaneously, for otherwise there is a risk—no, it is a certainty—that the two will bond. In fact, they have already bonded, just as much as would a human mother with her baby. The strong bond is inborn in all mammals. The terrible sound one hears on any dairy farm after a cow has given birth is the call of a lost calf, calling her mother, and the mother answering in desperation. If that is not suffering, I don't know the meaning of the word."
