The objective of the study was to evaluate the effects of dietary phytic acid (IP6) on the apparent total tract digestibility (ATTD) of main nutrients and apparent absorption of minerals in mink (Mustela vison). A basal moist diet consisting of fish meal, fish oil and wheat starch was added at different concentrations of soluble sodium phytate, thus obtaining six diets with graded levels of IP6 (0-19.9 g IP6 kg dry matter-1). Each diet was fed to four adult male mink kept in individual cages. There were no significant effects of IP6 on the ATTD of crude protein, fat, starch or energy, whereas the apparent absorption of copper and magnesium was significantly reduced with increasing concentration of IP6. Thus, as observed in other monogastric animals, we conclude that dietary IP6 could impair mineral status in mink, but may not affect digestibility of energy-yielding nutrients.

The fact that men and women are living longer than they have ever done before is something in which we can all rejoice. However, the process of ageing is associated with changes in skeletal, muscular, gastrointestinal, neural hormonal and metabolic processes that seriously affect an individual's performance and quality of life. Indeed, such changes can be contributory to a loss of independence in the elderly. This state-of-the art address highlights the main changes found to occur with ageing whilst simultaneously reporting findings of in vivo and in vitro studies designed to elucidate the potential of the Krebs cycle intermediate - alpha-ketoglutaric acid (AKG) in protecting elderly body systems from failing and degradation. The topics of paramount importance include impaired bone structure and strength, amino acid and mineral absorption, muscle performance, as well as highlighting the role of Krebs cycle intermediates in the debilitating changes that occur with end-stage renal failure and the regulation of the lipid metabolism. Finally, focus will be given to the role of 2-oxoglutarate as a potent protective factor in connection with the development of malignant cells in the body.
