Following the development of more accurate methods for lipid evaluation, various compounds have been discovered and studied as a way to improve and enrich diets to meet the animal requirements. Triglycerides are the major lipid component of diets and source of fatty acids that are used in the synthesis of important compounds as phospholipids. The fatty acids from phospholipids play a fundamental role in cell signaling and are substrates for specific enzymes in the synthesis of immune response mediators. Several […]

The energy value of foods as well as energy requirements of dogs and cats is currently expressed in terms of metabolizable energy (ME). The determination of ME content of foods requires experimental animals and is too expensive and time consuming to be used routinely. Consequently, different indirect methods have been proposed in order to estimate as reliably an accurately as possible the ME content of pet food. This work analyses the main approaches proposed to date to estimate the ME […]
