Abstract: (620 Views) |
| This study was performed to evaluate the effect of a phytogenic additive (herbal supplement) at different levels on growth performance, blood indices and immune responses of Siberian sturgeon (Acipenser baerii) for 8 weeks. For this purpose, Bioherbal® phytogenic additive was added to the diet in four levels of 0, 1, 2 and 3 g/kg in diet in three replicates. A total of 120 Siberian sturgeons with a mean weight of 5.36±0.50 g were introduced into twelve 80-L round plastic tanks with a density of 10 fish per each tank. Results showed that final weight, total length, weight gain, specific growth rate, and body weight increase were significantly higher than in fish fed Bioherbal at 3 g (p<0.05). In this treatment, feed conversion ratio had the lowest value and showed significant difference (p<0.05). The survival rate in all groups was 100%. Significant differences (p<0.05) were recorded in hematological and immune parameters. The number of red blood cells, contents of hematocrit, hemoglobin and mean corpuscular volume (MCV) in fish fed Bioherbal at 2 g and the number of white blood cells, lymphocyte percentage, lysozyme and IgM values in Bioherbal 3 g showed significant differences (p<0.05). Generally, based on the obtained data, it can be concluded that Bioherbal as a phytogenic additive at 3 g can enhance feed efficiency as well as improve hematological indices and strengthen immune system in Siberian sturgeon. |
