Description:
The present experiment measured digestible (DE) and metabolizable energy (ME) for fishmeal and soybean
meal on rainbow trout with 120 and 220 gr body weights. Chromic oxide (Cr2O3) was used as an external marker
and fecal collection method. The fishes were kept in metabolism chamber. Gross energy and chromic oxide values
measured in feces, fishmeal and soybean meal. DE obtained equal to 3700 and 3591 (Kcal/Kg) for fishmeal (with
62.5% CP) in 120 and 220 gr body weight of rainbow trout respectively, and for soybean meal (with 41.4% CP)
were 3004 and 2889 (Kcal/Kg) respectively. ME calculated and they were 3204 and 3110 (Kcal/Kg) for fishmeal
and also were 2601 and 2502 (Kcal/Kg) for soybean meal in two pointed weights respectively.
