Beef Calves. Most beef calves nurse from their mothers until weaning. When you separate and wean one depends on various factors, including forage availability and the cow's condition. If milk production is severely stressing the mother, earlier weaning is in order.
Perhaps the most significant one a baby hears in utero is his mother's voice. Around the seventh and eighth month, a fetus's heart rate slows down slightly whenever his mother is speaking, indicating that mom's voice has a calming effect. By the time they're born, babies can actually recognize their mother's voice. In one study, doctors gave day-old infants pacifiers that were connected to tape recorders. Depending on the babies' sucking patterns, the pacifiers either turned on a tape of their mother's voice or that of an unfamiliar woman's voice.
