摘要：

Multiple regression analysis was carried out for the results of digestibility determinations carried out with dogs fed 45 different dry extruded foods in which proximate nutrients, detergent fibre and alpha-linked plus free glucose (alpha-Glc) had been analysed. The following formula for estimating the digestible energy (DE) was found to be the most accurate: DE (MJ) = 21.7 x crude protein (kg) + 36.8 x total lipids (kg) + 17.3 x (alpha-Glc) (kg) (r(2)=0.99; s(xy)=2.8%) Inclusion of detergent fibre did not improve the accuracy of estimation.
