Effects of dietary Chinese herbal medicines mixture on growth performance, digestive enzyme activity and serum biochemical parameters of European eel, Anguilla anguilla
A feeding trial was conducted to investigate the effects of Chinese herbal medicines mixture (CHMM) on growth performance, digestive enzyme activity and serum biochemical parameters of European eels, Anguilla anguilla (initial weight 6.19±0.09 g). Diets with different supplementation of CHMM (0, 2.5...

Diets with different supplementation of CHMM (0, 2.5, 5, 7.5, 10, 12.5 g/kg) were given to eels for 42 days.

Eels fed with 5–12.5 g/kg CHMM presented a higher activity of enteric trypsin (TRS) (P<0.05). Meanwhile, an enhancement of amylase activity was observed in eels fed with 10 g/kg CHMM (P<0.05). Eels fed with 10 g/kg CHMM was observed a marked improvement in body protein content. The total superoxide dismutase activity (T-SOD) had a significant improvement among all experimental groups compared with the control group, and the lysozyme activity (LZM) was also enhanced by dietary 5 and 7.5 g/kg CHMM addition (P<0.05).

Regression analysis results show, 7.422, 7.343, 9.156, 9.085, 4.465 and 7.282 g/kg CHMM are the optimal addition for those parameters, respectively. In conclusion, dietary CHMM could improve the growth performance, enteric trypsin activity, body protein content, non-specific immunity and antioxidant capacity of eels, and the recommended supplementation of CHMM for European eels is about 9 g/kg.
