Abstract :

Abstract[1] Effects of dietary mannan oligosaccharides (MOS) on growth, survival and body composition of Litopenaeus vannamei were evaluated. Litopenaeus vannamei juvenile with an average weight of 2.5±0.12 g was stocked in fiberglass tank at a rate of 25 shrimp per tank and reared for 51 days. Experimental diets were prepared by using supplementation of 0 (Control), 1.5, 3.0 and 4.5 g MOS kg-1 commercial shrimp diet containing 38.7% protein and 3.85% lipid. At the end of the study, generally enhanced growth performance and feed efficiency were observed in shrimp fed on diet containing 3.0 g kg-1 MOS (P<0.05). There were no significant different in survival between treatments (P>0.05). The protein contents in the whole body increased with increasing rates of dietary MOS. In conclusion, 3.0 g kg MOS could be used as a healthy growth promoter in shrimp diets. *Corresponding Authors;: [e-mail]
