In this study, the effect of multi-enzyme Apszymee and betaine on the parameters of blood biochemical and body composition of (Huso huso) were studied separately and in combination. For this purpose, 126 fish with an average weight of 32 ± 3 gr were fed with dietary supplements containing 0, 1 and 1.5 percent of betaine at a concentration of 250 and 500 mg/kg of Apsozyme per kg of diet for 8 weeks. At the end of the study, blood biochemical factors and body composition were measured based on conventional methods of blood transfusion and body composition measurements. Based on the results of data analysis, the number of white blood cells showed a significant difference between the treatments. Although there was no significant difference between the treatments of Apsozyme and multi enzyme in experimental treatments, but in combined treatments, a significant increase in the number of white blood cells was observed. The number of red blood cells, hemoglobin, hematocrit, MCV, MCH and MCHC showed no significant difference in different treatments. Body data showed no significant difference in percentage of fat, protein, ash and moisture in experimental treatments. Therefore, it can be concluded that the use of betaine and multi enzyme did not have a significant effect on biochemical factors and carcass composition of Sturgeon fish.
