Abstract

The present study aimed to investigate the effects of replacing fish meal with Soybean meal and different levels of Kemin multi-enzyme on Growth performance, feed efficiency, body composition, fatty acid profile, and Gut lactic acid bacteria of beluga sturgeon (H. huso). Fish were fed with nine different diets (40% crude protein) including three different replacement levels of fish meal with Soybean meal 0 (as control), 40, and 80% and three different levels of Kemin multi-enzyme 0, 1, and 2 g/kg. Fish were fed with the experimental diets for 12 weeks at a rate of 1% of body weight per day. The replacement of fish meal with Soybean meal resulted in a reduction in Growth performance and the lowest weight gain and the highest feed conversion ratio was observed in the diet with 80% replacement. The highest weight gain, higher level of enzyme (2 g/kg), and lower feed conversion ratio were observed in the diet without Soybean meal. Similar results were recorded in treatment with 40% of Soybean meal, indicated the positive effect of utilization of enzyme on Growth performance. However, no significant difference was observed in final weight gain among different diets. Use of Soybean meal (0 and 40%) and Kemin multi-enzyme (2 g/kg) showed a higher percentage of protein in fish. Fatty acid profiles and lipid content (ranged from 11. 08 to 11. 74%) had significant differences among different treatments. Fish fed with the control group and diets with enzyme supplements (without Soybean meal) and diets 4 and 5 (0 and 1 g/kg enzyme and 40% Soybean meal) showed the highest level of n-3 Fatty acids and eicosapentaenoic acid. In contrast, diet containing 80% Soybean meal without enzymes (treatment 7) had the least n-3 Fatty acids, eicosapentaenoic acid, and docosahexaenoic acid. An increment was observed in the number of Lactococcus lactis, Lactobacillus carvatus, Pediococcus pentaseceous, Lactobacillus plantarum, and totally aerobic and anaerobic bacteria in all treatments. The highest number of bacterial was recorded in the diet containing 80% Soybean meal and 2 g/kg enzyme (treatment 9). The results of this study indicated that the replacement of fish meal with Soybean meal (up to 40%) in diet with enzyme at 2 g/kg can be suitable as a commercial diet for Beluga Huso huso.
