Abstract. Identifying the genetic and physiological background of phenotypic variability between animals of different nutrient turnover is a well recognised prerequisite for efficient breeding strategies. Published results relevant for our recently initiated project on properties of the nutrient transformation in cattle with respect to secretion type and accretion type are reviewed. For a deeper insight into the genetic and physiological background of both types, an experiment has been initiated using segregating F2 offspring's of crosses of Charolais bulls and German Holstein cows. It will be shown that, with respect to their phenotypic and physiological properties, these two breeds are especially suitable for a study of the accretion and secretion type. The basis of the experimental design and the intended investigations are described.
