Effects of Dietary Vitamin E Content on Growth Performance, Serum Biochemical Indices and Muscle Quality of Giant Freshwater Prawn (Macrobrachium rosenbergii)
摘要
Abstract
The experiment was conducted to investigate the effects of dietary vitamin E content on growth performance, serum biochemical indices and muscle quality of giant freshwater prawn (Macrobrachium rosenbergii) .A total of 750 healthy Macrobrachium rosenbergii juvenile shrimps with an initial body weight of (0.243±0.003) g were selected and randomly divided into 5 groups with 3 replicates per group and 50 shrimps per replicate.Shrimps in the 5 groups were fed 5 isonitrogenous and isoenergetic diets which contained 0.6 (control) , 103.4, 207.1, 412.9 and 631.7 mg/kg vitamin E, respectively.The experiment lasted for 62 days.The results showed as follows:1) compared with the control group, the weight gain rate and specific growth ratio in 103.4, 207.1, 412.9 and 631.7 mg/kg groups were significantly increased (P< 0.05) , the condition factor in 631.7 mg/kg group was significantly increased (P<0.05) .2) Compared with the control group, the glutamic pyruvic transaminase activity and total cholesterol content in serum in 103.4 mg/kg group were significantly decreased (P<0.05) ;the glutamic pyruvic transaminase and glutamic pyruvic transaminase activities and total cholesterol content in serum in 207.1 mg/kg group were significantly decreased (P<0.05) ;the serum glutamic pyruvic transaminase activity in 631.7 mg/kg group was significantly decreased (P<0.05) , and the serum triacylglycerol content was significantly increased (P < 0.05) .3) Compared with the control group, the muscle flesh content in 103.4 group was significantly increased (P<0.05) , and the muscle drip loss was significantly decreased (P < 0.05) ;the muscle flesh content in 207.1 group was significantly increased (P<0.05) , and the muscle cooking loss was significantly decreased (P<0.05) ;the muscle malondialdehyde content in 631.7 mg/kg group was significantly decreased (P<0.05) ;the muscle vitamin E content in 207.1, 412.9 and 631.7 mg/kg groups was significantly increased (P<0.05) .4) Compared with the control group, the springiness of muscle in 103.4 mg/kg group was significantly increased (P<0.05) ;the hardness, cohesiveness, chewiness and gumminess of muscle in 207.1 and 412.9 mg/kg groups were significantly decreased (P<0.05) ;the tenderness of muscle in 412.9 mg/kg group was significantly increased (P<0.05) .According to the broken-line regression analysis of specific growth ratio and cooking loss, we recommend the optimal dietary vitamin E content for Macrobrachium rosenbergii were 169.38 and 218.66 mg/kg, respectively.Based on our results, we conclude that dietary 169.38 to 218.66 mg/kg vitamin E can promote the growth performance, regulate the metabolism and enhance the immune, and effective improve the muscle quality of Macrobrachium rosenbergii.关键词
