| چکیده | ||
| In the present study effects of different levels of probiotic Pediococcus acidilactici, on growth performance and survival rate of Rutilus kuttum were investigated. Fingerlings Kutum with mean weight of 1±0.235 g were reared for 8 weeks in 500-l fiberglass tanks (15 fish per tank) with 4 diet treatments (with 3 replicates for each treatment). Treatments were included 1× 109 , 2:1×109 , 3× 109 CFU kg-1 dry food and without probiotic (control). At the end of the study, specific growth rate (SGR) and survival rate (SR) were higher in treatments supplemented with probiotic compared to control and its different were significant with together (p<0.05). Also, the fish fed with probiotics showed lowest food conversion ratio (FCR) significantly (p<0.05). The results of this study indicate that the use of 3× 109 CFU kg-1 dry food probiotics improved growth parameters and survival in Rutilus kuttum fingerlings. | ||
