Extract

Prediction of animal responses to supplementary nutrients has long been recognized as a problem in nutritional science (Kellner, 1926) that has still not been solved (Hanigan et al. ,2005). Another substantial problem is how to incorporate genetic differences into nutritional models (McNamara and Baldwin, 2000). These two problems are linked as their biological basis lies in the relative priorities of different life functions (growth, reproduction, health, etc.) and how they change both through time and under genetic selection. The purpose of this paper is to present recent developments in describing this biological basis and evidence in support of the concepts involved, using the cow as an example species.
