Interpretive Summary:

Technical Abstract: Energy is the most expensive component in livestock diets. Lipids are concentrated energy sources and are known to affect growth, feed efficiency, feed dust, and diet palatability. A large majority of research evaluating lipids in livestock has utilized lipids of high quality, dealt mainly with animal growth performance, and focused the research in younger animals. With the expansion of the use of lipids in human food products, the wide array of lipid sources available to the animal industry, and the potential of lipids to be of variable quality, a refresher in understanding lipid digestion, absorption, composition, and quality factors affecting their utilization is warranted. These proceedings will not only go through factors affecting the nutritional value of lipids to the animal industry, but will summarize recent research by the authors on measures of lipid quality and on the influence of consuming thermally oxidized lipids on physiological, metabolic, immunological, and growth indices in growing pigs.
