Abstract: (1375 Views) |
| This research was conducted with the aim of determining the effectiveness of using specific probiotics, separated from Acipenser stellatus, including Lactobacillus curvatus, Lactobacillus brevis, Lactobacillus sakei (with equal proportions) on the growth and immune indices of this species. The fish had an average weight of 64.94±0.22 g. This study with 4 experimental treatments (each treatment with three replications) including 0 mg (treatment 1), 150 mg (treatment 2), 300 mg (treatment 3), and 450 mg (treatment 4) specific probiotics per kg of food were performed for 8 weeks. A total of 144 pieces of Acipenser stellatus were randomly introduced in 12 fiberglass tanks with a total volume of 500 liters and a dewatering volume of 300 liters. Physico-chemical parameters of water were also measured and recorded daily. The results of this research showed that by adding specific probiotics at different concentrations to the diet, there was no significant difference in final weight gain, specific growth (p>0.05), but the treatment of 300 mg of probiotic showed better performance in diet. The results of this study showed that by adding native and specific probiotics in different concentrations to the diet, a significant difference was observed in the feed conversion ratio (p<0.05). The highest values of lysozyme and ACH50 were significantly observed in the treatment of 300 mg of probiotic per kg of food compared to other treatments (p<0.05). According to these results, it can be acknowledged that the use of specific probiotics in the food used for this fish can be effective in improving growth indicators and preventing possible diseases. |
