Abstract
This study was aimed at evaluating a novel Bacillus amyloliquefaciens B-1895 probiotic as a feed supplement for farmed trout. The final weight, indicators of absolute and average daily growth of fish, and the average daily growth rate were all higher in the probiotic group than the control (P<0.05). Moreover, probiotic-fed trouts had a more intensive growth rate than the control group (higher by 15.7%; P<0.05). A decrease in the feed coefficient was also observed in the probiotic group (decreased 25%; P<0.05), which indicated more effective digestion and assimilation of feed. For the probiotic group, a higher survival rate was observed compared to the control group (3% higher; P<0.05). In general, the introduction of probiotic in feed had no negative effect on the functional status of fish.
