Optimal dietary L‐ascorbyl‐2‐monophosphate inclusion improved the growth performance and nonspecific immunity of red swamp crayfish (Procambarus clarkii)

L‐ascorbyl‐2‐monophosphate (AMP) was used as a vitamin C source to investigate its effects on growth performance and nonspecific immunity of red swamp crayfish (Procambarus clarkii). Six experimental diets (AMP0, AMP15, AMP30, AMP45, AMP60 and AMP75) with different levels of AMP (.00, 141.01, 280.44...

Zusammenfassung:L‐ascorbyl‐2‐monophosphate (AMP) was used as a vitamin C source to investigate its effects on growth performance and nonspecific immunity of red swamp crayfish (Procambarus clarkii). Six experimental diets (AMP0, AMP15, AMP30, AMP45, AMP60 and AMP75) with different levels of AMP (.00, 141.01, 280.44, 419.06, 558.13 and 692.09 mg kg−1 diet, respectively) were fed to juvenile crayfish (average weight: .70 ± .01 g) for 56 days. At the end of the 56‐day trial, the highest final body weight, specific growth rate (SGR), phenoloxidase activity, lysozyme activity, superoxide dismutase activity and anti‐superoxide anion activity all occurred in the AMP30 group (p
