Those who keep dairy cows are faced with the perennial problem of preventing the calves from drinking up all their mothers’ milk. This problem is often solved by tying a thorny piece of wood to the calves’ heads, so that when they go to drink milk, the thorns prick the udders, causing the cows to shy away.
