The need to rear lambs artificially arises in the following situations: When the ewe is incapable of rearing triplet or quadriplet lambs efficiently, when there is a need to increase the rate of reproduction, when there are special requirements such as specific patogen free, or when milk becomes a marketable product. The objective of this review is to analyse the most important aspects related to artificial rearing of lambs including aspects such as: Colostrum intake, diet source of nutrients and formulation of milk substitutes, quantity of milk substitute fed, rearing techniques, performance and health, and last but not least, weaning. It has been shown that the application of physiological and nutritional knowledge is needed to rear lambs artificially mainly during the first six weeks of age; and that artificially reared lambs may grow as fast as naturally reared lambs if enough milk is provided and sanitary aspects are considered. In general terms, it is concluded that lambs of different breeds in a wide range of environments have been artificially reared successfully.
