Evaluation Of Thepax And Endo Vit. C As Growth Promoters For Common Carp Cyprinus Carpio

Abstract

The present study aims to evaluate the effect of Thepax and Endo Vit. C as feed additives on the growth performance of common carp Cyprinus carpio in cages earthen pond. A total of 600 common carp fish with an average weight of 163.41±10.16 g were distributed in the cages at a density of 100 fish/cage. Two replications for each treatment were used and three diets were formulated (27.84% crude protein), two diets with additives which included a control T1 (0% additives), T2 (1g/kg Thepax) and T3 (1g/kg Endo Vit. C). The highest value of the final weight was recorded in Thepax treatment (2209.34 g), followed by the Vit.C and the control treatment, and in all growth parameters (WG, DGR, RGR and SGR) statistical analysis showed significant difference (P≤0.05) between Thepax treatment with both Vit. C and control treatments. The survival rate was highest for Vit. C (99.5%), then Thepax (99%) and control treatment (83.5%). Feed utilization showed that the best food conversion ratio (3.14), PER (1.215) for Thepax, while PPV recorded highest value (20.379%) in Vit.C. Condition factor (K), reached the highest value (2.078) for Thepax treatment and the lowest value was for the control treatment. It was noted that body protein content of the Vit. C treatment was superior (17.94%), while it reached 16.10% for Thepax treatment, also the percentage of body lipid was higher after the experiment than the value before the experiment in all treatments. On the basis of the results obtained for above parameters, it was concluded that addition of 1g/kg Thepax in the diet recommended for common carp in earthen pond .
