Accuracy of the use of energy conversion factors for compound fish diets
Original language description
Conversion factors of 23.6, 39.5 and 17.2MJ/kg for protein, lipid and carbohydrate contents, respectively, are frequently used in fish studies to calculate the gross energy (GE) content of compound diets. Values predicted according to the above resultedin linear relationships of observed GE values with similar R2 and mean prediction error (MPE) values when using either nitrogen-free extract (NFE) (R2=0.5713, RMSE=1.3134, MPE=0.0741, n=129, 32 studies) or starch (R2=0.5665, RMSE=1.6768, MPE=0.0839, n=190, 45 studies) as measurements of carbohydrate content. Apparent digestible carbohydrate content (either NFE or starch) was found to be linearly-related (R2 values of 0.7531 and 0.7460, respectively) to its dietary content in compound fish diets. Predicted apparent digestible protein (ADP), lipid (DL) and carbohydrate contents, together with energy conversion factors, presented R2 and MPE values of 0.6205 (RMSE=1.2606) and 0.2051, respectively, between observed and predicted apparent dig
