After investigating the situation, Sgt. Patty Fisher informed neighbors that the sounds were of mother dairy cows lamenting the loss of their calves, who were taken from them shortly after birth. "It happens every year at the same time," Fisher said.
Many people are unaware that cows must give birth in order to produce milk. So that farmers can collect the milk themselves and sell it for human consumption, newborn calves are ripped from their mothers' sides about 24 hours after birth."
