Effects of Fish Meal Replacement by Common Cottonseed Meal and Fermented Cottonseed Meal on Growth Performance, Body Composition and Hepatopancreas Digestive Enzyme Activities of Juvenile Chinese Mitten Crab (Eriocheir sinensis)
摘要
Abstract
This experiment was conducted to investigate the effects of fish meal replacement by common cot-tonseed meal ( CSM) and fermented cottonseed meal ( FCSM) on growth performance, body composition and hepatopancreas digestive enzyme activities of juvenile Chinese mitten crab ( Eriocheir sinensis) . A total of 660 juvenile Chinese mitten crab with the average body weight of (0. 56 ± 0. 04) g were randomly assigned to 11 groups with 3 replicates per group and 20 crab per replicate. Eleven isonitrogenous (38. 39% crude protein) and isocaloric (19. 18 MJ/kg gross energy) experimental diets were formulated in which CSM supplemental levels were 0 , 8 . 0%, 16 . 0%, 24 . 0%, 32 . 0% and 40 . 0% ( named as groups CSM0 , CSM8 , CSM16 , CSM24, CSM32 and CSM40, respectively), and FCSM supplemental levels were 8. 0%, 16. 0%, 24. 0%, 32 . 0% and 47 . 5% ( named as groups FCSM8 , FCSM16 , FCSM24 , FCSM32 and FCSM47 . 5 , respective-ly) , respectively. The experiment lasted for 6 weeks. The results showed as follows: compared with the con-trol group ( group CSM0 ) , the weight gain rate, specific growth rate and survival rate of crab in groups CSM8 , CSM16 , FCSM8 , FCSM16 and FCSM24 had no significant differences ( P>0 . 05 ) . The whole crab crude protein content in groups CSM8 , FCSM8 , FCSM16 and FCSM24 also had no significant difference compared with the control group (P >0. 05). The weight gain rate, specific growth rate, survival rate and whole crab crude protein content were significantly lower than those in control group when CSM supplemental level was over 16% or FCSM supplemental level was over 24% ( P<0 . 05 ) . No significant differences were found among all groups in the contents of whole carb moisture, crude lipid and ash, and hepatopancreas lipase activity (P>0. 05). With the increase of the replacement level of CSM or FCSM, the activities of hepatopan-creas pepsin and trypsin were declined gradually, while the activities of amylase and cellulose were increased gradually. Under the same replacement level, the activities of pepsin and trypsin in groups FCSM were higher than those in groups CSM in different degrees, and the cellulase activity in groups FCSM was significantly low-er than that in groups CSM (P<0. 05). In conclusion, as protein sources to replace fish meal, 16% CSM or 24% FCSM is considered as the suitable supplemental level in the diet of juvenile Chinese mitten crab, and the replacement effect of FCSM is better than CMS under the same replacement level.关键词
