Dietary Effect of Withania somnifera (Ashwagandha) Root Powder on Growth and Blood Parameters of Cyprinus carpio (Common Carp)

Aims: 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.
