Elephants in a protected community in Kenya are being fed goat's milk as a less costly form of food.Workers at the Reteti Elephant Sanctuary in northern Kenya say the elephants enjoy drinking the goat's milk.They say the milk may be healthier for them than other choices.The sanctuary had been using powdered baby milk to feed the young animals it cares for.But it decided to test goat's milk, which costs less and is locally available.The sanctuary rescues young elephants that are found alone in the wild.It cares for them until they are old enough to be returned to the wild.Dr. Steven Chege is the sanctuary's medical advisor.He told Reuters news agency the goat's milk seems to be especially helpful to baby elephants."This is an animal that has just maybe lost a mother, they have been separated from their family," he said."So they get a lot of psychological traumas."
