玉米蛋白粉替代鱼粉对大菱鲆摄食、生长及体组成的影响
Replacement of fish meal by corn gluten meal in diets of Scophthatmus maximus
摘要
Abstract
The corn gluten meal (CGM) was evaluated as a replacement offish meal (FM) in a practical diet formulated to contain 50% protein and 12.5% lipid. FM was replaced by 0% ,12% ,25% ,38% ,and 50.5% of CGM(C0,C12,C25,C38 and C50.5)respectively. And another diet(C50.5CAA)was supplemental with a 1.80% essential amino acid ( CAA) mixture ( L-lysine: 1.2%, L-arg: 0. 6% ) based on the diet C50. 5. Juvenile Scophthatmus maximus( 12.51 ±0.02 g) were reared in an indoor, semi-closed recirculating system. Each diet was randomly fed to triplicate groups of 18 fish per tank (300 L) arranged in a completely randomized design. The fish were hand-fed to satiation twice daily for 49 days. At the end of the feeding trial, feed intake (FI), specific growth rate ( SGR), feed efficiency ratio ( FER) and protein efficiency ratio (PER) were significantly affected by the inclusion of CGM, with decreasing values as inclusion levels of CGM rose. There were no significant differences(P >0.05) in growth performance between fish fed diet CO and C12. However,fish fed diet containing above 25% CGM had significantly lower(P <0.05) growth than those fed diet CO and/or C12. Supplementation with CAA significantly improved FER of fish(P <0. 05), and FI, SGR and PER of fish also showed a tendency to be improved by supplement with CAA. Body composition, serum triglycerides and serum urea of the fish were not significantly (P >0. 05) affected by dietary treatments. Total cholesterol concentration in serum of fish was significantly reduced with increasing dietary CGM level (P < 0.05).关键词
