One of the big preventable losses of the Western sheep business at the present time is the orphan lamb. There are a number of conditions, anyone of which may result in a motherless lamb; the ewe may die (this probably does not occur in a large number of cases) ; a mother may refuse to claim one of a pair of twins or even a single lamb; mother and lamb may become separated by the ordinary moving about of the band of ewes and the ewe thereby loses the scent of the lamb.
The careful shepherd soon detects the orphans, but he is powerless to save them unless provisions are made to give them the special care their successful raising demands. Even where they are taken to the home ranch the attempt to raise them without a mother is not by any means always successful.
