Abstract
The study investigated the effects of substituting fishmeal with different levels of hydrolyzed protein on the serum biochemical composition and immune system of beluga (Huso huso) fry over a 48-day period. A total of 750 fish were randomly assigned to five groups: a control group (no hydrolyzed protein), three groups with varying levels of hydrolyzed protein (2.75%, 5.5%, and 8.25%), and a positive control group (commercial feed). The study found significant differences in glucose levels among the groups (P<0.05), with the control group having the highest glucose level. Treatment 2 had the highest total protein and lipid levels, which significantly differed from the other groups (P<0.05). Liver enzyme levels (ALT, AST and ALP) did not vary significantly among the groups (P>0.05). There were no significant differences in cholesterol levels (P>0.05). Regarding immune factors, treatment 2 exhibited significantly higher total immunoglobulin levels compared to all other groups except for treatment 3 (P<0.05). Lysozyme levels did not differ significantly between the control group and treatments 1, 3, and 4 (P>0.05); however, treatment 2 displayed the highest level. IgM and ACH50 activity did not differ significantly across all groups (P>0.05). In conclusion, replacing fishmeal with hydrolyzed protein at a concentration of 2.75% to 5.5% improved performance in blood biochemical and immune parameters of beluga fry when compared to the control group.
