Fish fed 1% Previda™had a significantly higher (Pb0.05)
weight gain than fish fed the basal diet and the diet supplementedwith
Bio-MOS®; however, therewere no differences among fish fed FOS, GOS
and Previda™. Feed efficiency and protein efficiency ratio values were
not significantly (PN0.05) affected by the diets supplemented with
prebiotics, although fish fed the basal diet had the lowest numerical
values. Survival of fish during the 8-week trial was lowest for the Bio-
MOS® fed fish (58.3%) and above 80% for all other dietary treatments,
although these differences were not statistically significant (PN0.05).
