Abstract

The polyphenol resveratrol is an antioxidant nutrient, used to enhance growth performance through activation and modification of gut function and structure and to inhibit cancer initiation and promotion. The main application of resveratrol is in animal and poultry nutrition, in particular as a feed additive to reduce free radicals in a wide variety of animal species. Several studies carried out on diets supplemented with additives containing natural antioxidants as resveratrol demonstrated its capability to improve the productive performance, immune response and health of livestock besides reducing the risks of various animal diseases such as cancer and other degenerative diseases. Such activities could be attributed to its powerful antioxidant, immunomodulatory and anti-inflammatory effects by preventing free radicals from interacting with cellular DNA and its ability to alter the intestinal microbiota, increased digestibility and absorbance of nutrients. This review describes the modes of action, metabolism, the biological activities, natural sources and beneficial aspects/potential applications of resveratrol in animal and poultry nutrition, production and health.
