Abstract
1. A new method of determining dietary metabolisability of energy and digestibility of fatty acids is described. 2. The method requires the digestion of the faecal sample with 4N NC1 and ashing the residue. 3. Comparisons with the "total collection" method that the 4N HC1-insoluble method has similar accuracy.
