nutrigenomics: a new approach to feed formulation

Nutrigenomics is the study of the effect of nutrition on gene expression which discusses how dna isconverted to mrna and then converted mrna to protein, and is the basis for understanding the biologicalactivity of edible compounds. nutritional manipulations and nutritional approaches are key tools toinfluence the performance and health of organisms. today, it has been shown that better nutrition ofanimals selected for further production has a beneficial effect on their function. despite the importanceof this issue in production systems, there are no ways to clearly explain the molecular mechanisms ofthese changes. this review study aimed to investigate nutrigenomics as a molecular approach to theexpression of genes involved in the health and growth of organisms. searching was conducted in scopus,pubmed, sciencedirect, iranmedex, and google scholar databases on the studies conducted during1990-2018 by using the keywords: “nutrigenomics”, “gene expression”, “nutrients”, “food formulation”.initial stage yielded 120 articles. after excluding conferences papers, 58 remained for the final review.there are a limited number of nutrigenomics studies on the laboratory and farm animals, but it has beenconfirmed that there is an association between nutrition, genetics, fertility and growth. therefore, theuse of nutrients that can express gene expression in a way that improves the function and efficiency oforganisms is essential in feed formulation as a new approach in nutrition.
