摘要:

为探究餐厨垃圾耦合培养的小球藻饲料对罗氏沼虾生长性能、基础营养成分和品质的影响,以大塘养殖罗氏沼虾为试验对象,在基础饲料中添加0.1%小球藻饲料,进行30 d的养殖试验,测定其生长性能、基础体成分和肌肉营养成分。试验结果显示,添加0.1%小球藻饲料能够提高罗氏沼虾的终末平均体重、终末平均体长、质量增加率和特定生长率,差异不显著(P>0.05)。添加小球藻饲料有助于提高虾体的粗蛋白、粗脂肪、粗灰分、Ca、P等含量,差异不显著(P>0.05);此外,添加小球藻饲料能提高虾体的部分必需氨基酸含量和不饱和脂肪酸含量,其中单不饱和脂肪酸含量是对照组的2倍,多不饱和脂肪酸含量比对照组提高了25.6%,油酸、花生一烯酸和亚油酸含量分别达1 131.10、24.87和768.91 μg·mL-1,显著高于对照组(P<0.05),具有较高的食用价值与保健作用。

Abstract:

The aim of this experiment is to investigate the effects of feed prepared by cultivating Chlorella vulgaris with food waste on the growth performance, basic nutritional components, and quality of Macrobrachium rosenbergii. The experiment focused on Macrobrachium rosenbergii, which is cultivated in large ponds and feeded with 0.1% Chlorella vulgaris feed and basic feed. A 30-day cultivation experiment was conducted to determine the growth performance, basic body components, and muscle nutritional components. The experimental results showed that adding 0.1% Chlorella vulgaris feed could improve the final average body weight, final average body length, mass increase rate, and specific growth rate of Macrobrachium rosenbergii to certain extent (P>0.05). Meanwhile, adding Chlorella vulgaris feed increased the contents of crude protein, crude fat, crude ash, Ca, and P in shrimp (P>0.05); In addition, the supplement of Chlorella vulgaris feed can increase the contents of some essential amino acids and unsaturated fatty acids in shrimp bodies. The content of monounsaturated fatty acids was twice that of the control group and the contents of polyunsaturated fatty acids increased by 25.6% compared with the control group. The contents of oleic acid, arachidonic acid, and linoleic acid reached 1 131.10, 24.87, and 768.91 μg·mL-1, respectively, which were significantly higher than those in control group (P<0.05). The results indicated the high edible value and health benefits of Chlorella vulgaris feed.
