Özet
The study was conducted to investigate the effects of dietary fig extract and onion extract supplementation in diet on growth performance, feed utilization, biometric indexes in common carp ( Cyprinus carpio ). For this purpose, fig and onion extract were added to experimental diets at the rate of 1,3,5 g / kg respectively. Fishes were fed with trial feed for 90 days. At the end of the trial period, weight increase and specific growth rate of the fishes fed with the feed containing 1.3 g/kg fig extract and 1.3 g/kg onion extract were found to be higher than the control group; food conversion ratio was found to be lower than the control group (p<0.05). Hepatosomatic index and viscerosomatic index amounts of the fishes fed with fig extract and onion extract feeds were found to be lower than the control group; and spleen somatic index was found to be higher than the control group (p<0.05). The amount of visceral organ fat index was found to be lower among the fishes fed with the feed containing fig and onion extracts compared to the control group (p>0.05). These results indicate that dietary supplementation of 1.3 g/kg fig extract in the commercial diets could improve some biometric indexes.
