From this study, the results show that TMAO has a positive effect on reducing stress and that inclusion of TMAO in a diet containing SBM may improve performance, ultimately allowing for increased use of SBM containing TMAO in fish diets.
It is expected that dietary TMAO will facilitate even better growth in marine ?sh than rainbow trout. Next steps include examining its use in marine fish species that are highly sensitive to SBM, such as Atlantic salmon.
• Fish consuming diets with 40% SBM alone showed signs of distal intestine inflammation (enteritis)
• Inclusion of TMAO in the diet helped suppress intestinal inflammation and increased growth when included at the right concentration
• SBM with TMAO slightly improved histological signs of distal enteritis
• SBM with TMAO signi?cantly showed differences in serum proteins associated with stress and gene expression
