The Apparent Digestibility of the Non-nitrogenous Fraction of Pig Feeds

Abstract

A simple method for the estimation of the digestible non-nitrogenous fraction of normal pig feeds is described. It requires only knowledge of the digestibility coefficient of the crude protein contained in the dry matter of the feed. More accurate estimates can be obtained by applying to this method a simple correction involving only the crude protein content of the dried feed. Attention is drawn to the intimacy of the relationship between the digestibility of the non-nitrogenous and nitrogenous components of the diet.
