Abstract:
The present study was carried out to evaluate growth promoting effect of Allium sativum, Curcuma longa, Tinospora cordifolia, Withania somnifera, Vitamin C and chitosan on the fingerlings of Cyprinus carpio haematopterus. The fingerlings weighing 33.0 ± 2 g were distributed randomly into four treatment groups T₀, T₁, T₂ and T₃ of 25 fishes each in triplicate. Four Isoproteinous experimental diets were prepared by mixing rice bran, deoiled mustard oil cake, deoiled soybean cake and vitamin-mineral mixture. The phytobiotics, Vitamin C and Chitosan were incorporated into diet as [Diet (D₁) with control feed + 2.5 gm of garlic + 2.5 gm of guduchi + 2.5gm of turmeric +2.5 gm of ashwagandha. Diet (D₂) with control feed + (2.5 gm of each plant) + 25 mg Vitamin C. Diet (D₃) with control feed + (2.5 gm of each plant) + 2.5 gm Chitosan]. T₀ group fishes were fed with D₀ diet, T₁ with D₁, T₂ with D₂, T₃ with D₃ @ 5% body weight per day for 102 days. The water quality parameters were regularly monitored. Fingerlings fed with diet D₃ achieved higher Net weight gain (NWG 17.49 ± 0.2461 g), specific growth rate (SGR 0.197 ± 0.0018 %), gross conversion efficiency (GCE 0.7478 ± 0.0019), better feed conversion ratio (FCR 1.337 ± 0.0057) and protein efficiency ratio (PER 1.158±0.0112) as compared to other treatments. The obtained results indicated that T₃ was the best treatment which realized significant (P<0.05) increase in parameters related to growth performance. The results indicate that phytobiotics along with vitamin C and chitosan have very good growth promoting effect and does not have any adverse effect on health of Cyprinus carpio haematopterus in culture system.
