Abstract

The study investigated the effect of increasing dietary inclusion of Mannan oligosaccharide (MOS) on growth and blood parameters of sea bream (Sparus aurata). Vary ing concentrations of M OS were added to commercial sea bream feed at 0‰ (control), 1, 2, 3 and 4‰. At the end of the 15 week trial, control group had the highest final weight, sp ecific growth rate, feed conversion ratio and protein efficiency ratio (P0.05). Survival rates were higher in the MOS treatment groups. Blood parameters, did not differ among treatment groups (P>0.05). The lowest Alkaline phosphatase (ALP) value was measured in the control group wheras the highest was recorded in the 4‰ MOS group. The lowest level of trigly cerid es was measured in the 4‰ MOS group, while the highest lev el of triglycerides was measured in the control group. Cholesterol level was lowest in the 2‰ MOS group (P<0.05). The study showed that the inclusion of dietary MOS has no negative effects on growth and blood p arameters in sea breamş. However, dietary MOS inclusion led to higher survival rate in trial fish. © Published by Central Fisheries Research Institute (CFRI) Trabzon, Turkey.SUF2011D9 ÜD/13/A-11/P-01/01This study was supported by TAGEM/HAYSÜD/13/A-11/P-01/01 and by the Research Fund of University of Çukurova (SUF2011D9)
