Fecha de publicación: | 25-abr-2017 | Editor: | Taylor & Francis | Citación: | Journal of Applied Aquaculture 29(2): 183-196 (2017) | Resumen: | A study was designed to investigate the possible positive prebiotic effects of mannan oligosaccharides (MOS) on growth and reduction of anxiety behaviors in zebrafish (Danio rerio). The experimental diets were supplemented with 0, 2, 4, 6, or 8 g MOS kg−1 and were fed to juvenile fish (0.47 ± 0.017 g) in triplicates for six weeks. Significant differences were found in the final body weight, body weight intake, percent body weight intake, and specific growth rate among treatments. The regression analyses showed that the optimum MOS level was 4–4.1 g MOS kg−1 diet. Fish fed 4 g MOS kg−1 feed showed higher survival than the other treatments. Also, using the novel tank test, fish fed with 4 g MOS kg−1 diet showed lower anxiety by swimming in the upper portion of the tank. The other behavior parameters remained unaffected by the prebiotic. The results indicated the beneficial effect of the prebiotic MOS on growth and partly on welfare of zebrafish juveniles. | Versión del editor: | https://doi.org/10.1080/10454438.2017.1306732 | URI: | http://hdl.handle.net/10261/173772 | DOI: | 10.1080/10454438.2017.1306732 | ISSN: | 1045-4438 | E-ISSN: | 1545-0805 |
