Dietary Effect of Withania somnifera (Ashwagandha) Root Powder on Growth and Blood Parameters of Cyprinus carpio (Common Carp)
Get PDFAims: The present study evaluated the effect of different levels of Withania somnifera root powder in fish formulated diets on the growth performance of economically important freshwater fish species in Asia Cyprinus carpio and compare the hematological changes occurred in fishes fed with control feed and herbal formulated diet.
Study Design: The experiment was planned with the size group of 30.0±1.0g. Fish of the respective size group of Cyprinus carpio were subjected to different herbal formulated diets at a concentration 0%, 0.5%, 1.0%, 1.5%, 2.0% of Withania somnifera root powder extract through their diet, while the control group received a standard diet without any supplementation.
Duration of Study: The study was conducted over a period of 4 weeks.
Methodology: During which growth parameters such as Average Daily Growth, Specific Growth Rate and Absolute Growth Rate were monitored at regular (10 days) intervals. The blood samples were collected at 4th week from each group to assess hematological parameters including Red Blood Cell count, White Blood Cell count, Hemoglobin, Total Cholesterol and Total serum protein levels. The overall results revealed that the inclusion of Withania somnifera extract in the diet of Cyprinus carpio significantly influenced both growth and blood parameters.
Results: Fish exposed to Withania somnifera extract exhibited enhanced growth performance compared to the control group, with increased Average Daily Growth, Specific Growth Rate and Absolute Growth Rate. Moreover, hematological analysis revealed positive effects on the blood parameters of treated fish, including improvements in Red Blood Cell count, White Blood Cell count, Hemoglobin, Total Cholesterol and Total serum protein levels.
Conclusion: The overall results revealed that the inclusion of Withania somnifera extract in the diet of Cyprinus carpio significantly influenced both growth and blood parameters
Green Synthesis of Silver Nanoparticles from Phyllanthus emblica (Indian Gooseberry) for Potent Antimicrobial Efficacy
Get PDFNowadays cost-effective and environmentally friendly technologies for nanomaterial synthesis have gained attention in the biosynthesis of nanoparticles. The present study is focused on synthesizing silver nanoparticles using Phyllanthus emblica for a green approach. UV-Vis Spectrophotometry, XRD, SEM, and FTIR were used to characterise the synthesised silver nanoparticles. It was determined that spherical shaped nanoparticles by SEM examination, which revealed that the average particle size was 20 nm. Antibacterial activity of AgNPs analyzed with the help of Staphylococcus aureus, Vibrio cholerae, Pseudomonas auriginosa, and Bacillus subtilis bacteria, and the result shows that a higher concentration of AgNPs is increasing as well as a zone of inhibition increased
Effect of Calotropis procera (Aiton) Dryand. based zinc oxide nanoparticles on the cotton pest Spodoptera litura Fab.
No full text224-229Major loss in agricultural crops is caused by insect pests. In India,
various synthetic insecticides are used against pests. These are much
expensive and cause environmental hazards. The nanoparticles, as an
alternative approach is gaining considerable interest in this field. In the
present study, we explored the biological synthesis of zinc oxide
nanoparticles using Giant milkweed, Calotropis procera (Aiton)
Dryand. and its effects on the tobacco cutworm, Spodoptera litura. The
reduction of zinc ions (Zn2+) to zinc nanoparticles (ZnO NPs) was
prepared by mixing 50 g of C. procera leaves with 100 mL of single
distilled water in a 250 mL glass beaker. To synthesize nanoparticles,
50 mL of C. procera leaf extract was taken using a stirrer-heater and 5 g
of zinc oxide was added at 60ºC, boiled, then kept in a hot air oven at
70ºC for 24 h. Finally, the obtained light yellow coloured powder was
carefully collected and characterized using X-ray diffraction (XRD)
analysis. The results revealed that the biologically synthesized zinc
oxide nanoparticles pesticide was highly effective against the pest. The
weight of the pest decreased from low concentration to high
concentration. It is concluded that the Calotropis Procera based zinc
oxide nanoparticles could be used for the control of Spodoptera litura
Bioefficacy of marine seaweed Sargassum wightii Greville ex J.Agardh extracts on the growth of Bombyx mori (L.) larvae
No full text62-66Marine algae are renewable living resources that are a rich source of structurally important novel and biologically active secondary metabolites. These seaweeds are economically valuable resources, used as food, fodder, fertilizer, and medicine and thus useful to mankind in many ways. In the present study, the brown alga, Sargassum wightii Greville ex J. Agardh (SW) has been analyzed for secondary metabolites using three solvent extracts (acetone, ethyl acetate and water), and were tested for growth efficacy at five different concentrations (100, 200, 300, 400 and 500 ppm) on the mulberry silkworm Bombyx mori (L.) third instar larvae by leaf dip method. Extraction rate of S. wightii water extract was 1.3 g (F= 1399.29; df=3, 36; p=0.005); ethyl acetate extract was 0.7 g (F= 30.76; df=3, 36; p=0.005); and acetone extract was 0.4 g (F= 1399.29; df=3, 36; p=0.005). Results have shown the presence of steroids, such as tannins, phlobatannins and saponins; flavonoids, phenolic compounds and xanthoproteins in these extracts obtained by cold percolation method. The seaweed extract enhanced the growth of silkworm larvae B. mori with increased concentrations. The highest concentration (500 ppm) of water extract showed more growth rate than the control. The 100, 200, 300 and 400 ppm of water extract showed maximum growth comparable to the control at 96 h of our study period. This finding envisages that secondary metabolites could be extracted with the cold percolation method and can be used for biological and agricultural lead
