Abstract
This study was carried out to evaluate the effect of different levels of Multi-Behzime on growth performance and proximate composition of rainbow trout (Oncorhynchus mykiss) juvenile. A total of 600 specimens with mean weight (±SD) of 18±2 gr were stocked as 50 fish per treatment in completely random design with four treatments each in in three replicates. Experimental diets containing four levels of the Multi-Behzim i.e. 200, 400 and 600 mg.kg-1 with a control fed for 45 days. The results showed no significant (P>0.05) differences in growth performance and feeding efficiency of fish fed with the experimental and control diets. Whereas whole body chemical composition of O. mykiss juveniles revealed significantly (P<0.05) lower moisture (70.23±0.11) and total ash (2.25±0.08) as well as higher crude protein (19.47±0.24) and crude lipid (7.56±0.10) content in 600 mg.kg-1 treatment. It could, therefore, be concluded that 600 mg Multi-Behzime enzyme per kg of diet can improve carcass quality of O. mykiss juvenile.
