The system in which a lamb is raised by another ewe is known as fostering. Fostering is a management practice commonly used in sheep farming, whereby a lamb is removed from its biological mother and placed with another ewe that is not its biological mother. The ewe that takes on the lamb acts as a foster mother, providing milk and care for the lamb as if it were her own offspring. This can be necessary if the biological mother has died, has too many lambs to care for, or if a lamb is rejected by its mother. In contrast, rearing refers to the general process of raising young animals, which includes feeding, care, and management until the animal reaches maturity. Weaning refers to the process of gradually transitioning a young animal from its mother's milk to solid food, typically by removing it from the mother's care and feeding it alternative sources of nutrition. Therefore, fostering is the correct term to describe the system in which a lamb is raised by another ewe.
