Dietary thiamine requirement and its effects on glycolipid metabolism in oriental river prawn (Macrobrachium nipponense)

A 10-week feeding trial was conducted to investigate the optimal dietary thiamine requirement of oriental river prawn Macrobrachium nipponense with the effects on glycolipid metabolism evaluated. A total of 960 prawns with an average weight of 0.18 g were selected and randomly fed six semi-purified...

Description
Summary:A 10-week feeding trial was conducted to investigate the optimal dietary thiamine requirement of oriental river prawn Macrobrachium nipponense with the effects on glycolipid metabolism evaluated. A total of 960 prawns with an average weight of 0.18 g were selected and randomly fed six semi-purified diets containing graded levels of thiamine (14.10, 35.20, 43.30, 61.40, 95.60 and 165.00 mg/kg, respectively) in an indoor water circulation system. Each diet was tested in 4 replicates. Final weight, weight gain, specific growth rate, protein efficiency rate, hemolymph thiamine and triglycerides concentrations all increased significantly (P
