Effect of Chlorella vulgaris feed prepared from kitchen waste phase change liquid on the growth performance and nutrient composition of Macrobrachium rosenbergii
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.
