本试验旨在研究裙带菜对斑节对虾生长、免疫和肠道结构的影响。试验用裙带菜添加量分别为0%、1%、2%、3%、4%、5%和6%的7种配合饲料饲喂平均初始体重为0.69 ± 0.03g的斑节对虾幼虾，试验期为56 d。结果表明，随着饲粮中裙带菜添加量的增加，增重和特定生长率均呈现先增加后降低的趋势，2%裙带菜组的增重和特定生长率达到最大值，与其他组差异显著（P<0. 05）。饲料转化率随饲料中裙带菜添加量的增加呈先降低后升高的趋势（P< 0.05），2%裙带菜组的饲料转化率最低，为1.13。蛋白质利用率（PER）和蛋白质沉积率（PR）随饲料中裙带菜含量的增加呈先增加后降低的趋势，2%裙带菜组的PER和PR值最大，与其他组差异显著（P< 0.05）。3%裙带菜组对虾的全蛋白质含量显著高于0%和1%裙带菜组（P< 0.05），但与其它组差异不显著（P> 0.05）。摄食3%和4%裙带菜饲料的对虾体脂肪含量显著高于其它饲料组（P< 0.05）。添加0%裙带菜组的超氧化物歧化酶（SOD）活性显著低于添加6%裙带菜组（P< 0.05），但与其他组差异不显著（P> 0.05）。酚氧化酶（PO）活性以2%~ 6%裙带菜组较高，但各组间差异不显著。肠褶的高度和宽度分别以1%和3%裙带菜组最高。通过对蛋白质沉积率和水溶性蛋白质沉积率的二次多项式回归分析表明，裙带菜的最佳添加量为2.17%~ 2.87%。
This experiment was conducted to investigate the effects of dietary wakame on growth, immunity and intestinal structure ofPenaeus monodon. Seven formulated diets with seven different levels (0%, 1%, 2%, 3%, 4%, 5%, and 6%) of wakame were fed to triplicate groups of juvenilePenaeus monodon(mean initial weight 0.69 ± 0.03 g) for 56 days. After the 56-day trial, results showed that weight gain (WG) and specific growth rate (SGR) were firstly increased and then decreased with increasing dietary wakame levels; the maximum values of WG and SGR were found in 2% wakame diet treatment and showed significant differences with other diet treatments (P< 0.05). Feed conversion ratio (FCR) was firstly decreased and then increased with increasing dietary wakame levels (P< 0.05), the minimum value of FCR was 1.13 in 2% wakame diet treatment. Protein efficiency ratio (PER) and protein retention (PR) were also firstly increased and then decreased with increasing dietary wakame levels; the maximum values of PER and PR were found in 2% wakame diet treatment and showed significant differences with other diet treatments (P< 0.05). Whole body protein content of shrimp fed 3% wakame diet was significantly higher than that of shrimp fed 0% and 1% wakame diets (P< 0.05) but without significant difference with shrimp fed other diets (P> 0.05). Whole body lipid contents of shrimp fed 3% and 4% wakame diets were significantly higher than that of shrimp fed other diets (P< 0.05). Superoxide dismutase (SOD) activity of shrimp fed 0% wakame diet was significantly lower than that of shrimp fed 6% wakame diet (P< 0.05) but without significant difference with shrimp fed other diets (P> 0.05). The higher phenoloxidase (PO) activities were found in shrimp fed 2%–6% wakame diets and showed no significant difference among them. The highest values of the intestinal folds height and width were found in shrimp fed 1% and 3% wakame diets, respectively. Second-degree polynomial regression of WG and protein retention indicated that the optimum supplement of dietary wakame should be 2.17%–2.87%.
