Abstract

A 2-month experiment was conducted with three groups (control group, Group 1, and Group 2) to study the effect of gingerol on the growth performance, digestive enzyme activities, and antioxidation of Macrobrachium nipponense. The results indicated that gingerol, when used as an additive at different feeding frequencies, had different effects on the growth performance of M. nipponense. The weight gain rate (WGR) of Group 1 (fed gingerol once a week) was 57.89 ± 6.53%, significantly higher than both the control group and Group 2 (fed gingerol twice a week) (P < 0.05). On the 60th day of the experiment, Group 1 had the longest average body length and highest body weight. The yield in Group 1 was also the highest (55 kg–60 kg per mu), while Group 2 had the lowest. Furthermore, we found that gingerol enhanced SOD activity, reduced MDA content, and improved the activities of pepsin, α-amylase, and β-amylase, thus promoting the anti-oxidation and digestive enzyme activities of M. nipponense. However, it is important to restrict the feeding frequency. In our study, using gingerol as an additive once a week for 60 days showed the optimal effect.
