Nutritional stress causes changes in the circulating levels of a number of hormones that regulate metabolic function and reproduction. Effects of nutritional stress are more profound in small mono-gastric animals which have low body stores. Less effects are seen in large animals, especially ruminants. Nutritional status affects the hypothalamic-pituitary-adrenal axis, most likely via effects of leptin, ghrelin and insulin. These effects may be directly on the cells of the paraventricular nucleus or indirectly through "appetite regulating" systems within the brain. © 2007 Copyright © 2007 Elsevier Inc.
