Effects of dietary probiotics and probiotics combined with enzymes on growth performance of rainbow trout (Oncorhynchus mykiss)

Rainbow trout (Oncorhynchus mykiss) is a popular aquaculture species, often faces health and growth challenges due to high stocking density. To address these issues, the present study focused on evaluating impact of dietary supplementation performance rainbow using probiotics as well combined with enzymes. Four groups fry, each an average size 1.423±0.002 g, 1.412±0.096 1.451±0.136 g 1.477±0.118 were individually placed in experimental tanks names T1, T2, T3, T4, respectively. T1 received supplement 6 gm. Dige pro 2 gel per kg feed. T2 Multizymes feed T3 3 pro, Multizyme At end 90-day period, findings showed that Multizyme-p Gel (T2) significantly improved terms weight gain survival rate compared both control group other treatments.
