Abstract

Lipids are an important source of fatty acids (FA) and energy, which are essential for biological processes and influence the regulation of transcription. Pigs are an excellent model for the study of nutrigenomics, particularly lipid metabolism, because the deposition and composition of FA in their tissues reflects the composition of FA in their diet. Studies of the influence of dietary components and their effects are fundamental to nutrigenomics, or the study of how nutrients can act as cellular sensors to influence biological processes and gene expression in various tissues. Recent studies show that the use of FA in pig diets is important for production systems because it can improve the energy value of the diet, help reduce costs, improve animal welfare, and influence the nutritional value of the meat. Studies show that FA such as oleic acid (OA), linoleic acid (LA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA) are important for animal and human health, associated with the regulation of transcription in tissues such as muscle, liver, adipose tissue, and brain. Because of the importance of FA to biological processes, pig health and production, and the health of pork consumers, this review focuses on dietary FA used in pig production and their relationship to biological processes in different tissues.
