Soya bean-based diets plus probiotics improve the profile of fatty acids, digestibility, intestinal microflora, growth performance and the innate immunity of beluga ( Huso huso )
This study was conducted to investigate the effect of different methods of using probiotics Bacillus subtilis and Bacillus licheniformis in soya bean‐based diets on the physiology of beluga (Huso huso ) (3514g).

| Summary: | This study was conducted to investigate the effect of different methods of using probiotics Bacillus subtilis and Bacillus licheniformis in soya bean‐based diets on the physiology of beluga (Huso huso ) (3514g). Five experimental diets were formulated to feed beluga for 10weeks. The results showed that there was no significant difference in weight gain between control (446g) and 70%SBM‐SPRAY2 (409g) treatments. Long‐chain polyunsaturated fatty acids in the muscle of beluga fed control (203.2g/kg) and 70%SBM‐SPRAY2 (166.4g/kg) diet did not change statistically. Blood performance as a newly introduced factor in individuals fed dietary control (64.06) and 70%SBM‐SPRAY2 (64.33) had higher value as compared with those fed dietary 70%SBM‐DIET2 (61.90) ( p <0.05). Also, total protein (1.68g/dl) and RBC (0.7410 6 /mm 3 ) in fish fed 70%SBM were statistically lower than other treatments ( p <0.05). Lysozyme, alternative complement activity and total viable counts in beluga fed dietary probiotics were significantly higher than others. In conclusion, feeding fish with the 70%SBM‐SPRAY2 diet improved fish growth and health. |
