Abstract :
Abstract[1] Nucleotides improve immune and digestive systems by various functions such as effecting on immune system, cell metabolism and absorption off at and protein. Recently, they has been considered widely in aquaculture. In this study, effects of dietary nucleotides on the growth, survival and some hematological indices of common carp (Cyprinus carpio, N=240) were investigated. Three levels of nucleotides (0.5, 1 and 1.5%) were added to fish diet. The fishes (Weight=4.74±0.2 g, replication=3) were fed on the diet and a group of fish were fed on a diet without nucleotide as the testing group for 8 weeks. After 8 weeks of treatment diet containing %1 nucleotide significant increase in relative food eaten revealed that, compared to control (P<0.05). The other growth parameters such as weight gain, feed conversion ratio, specific growth rate and feed conversion, daily and found no significant treatments (P>0.05). Hematology parameters measured results showed that nucleotides have had a positive effect on blood parameters and the highest white blood cells, red blood cells and hemoglobin were observed in treatments containing nucleotides (P<0.05). The survival rate was also significantly different between treatments (P>0.05). The results suggest that dietary nucleotides in levels 1and 1.5% had positive effects on common carp Hematology parameters. * Corresponding Authors; Email: t.lukhi3@yahoo.com
