Abstract: Starvation results from the inadequate intake of nutrients or the inability to metabolize or absorb nutrients. Farm animals may be deprived of water or food during extremely poor feed and water conditions, or during a long period of shipment. The aim of this chapter is to highlight, according to the existing data, how starvation results on sheep organism indicating the changes on biochemistry and molecular level. Specific attention is given to the different physiology between ruminant (sheep) and non ruminant species and on mechanisms that involved in lipogenesis / lipolysis. In addition, future aspects of research are discussed. The presented data could serve not only as basis for understanding the main physiology of starvation and further basic research on sheep, but also as a basis for any animal scientist to develop new concepts and methods for use in improving animal production.
