چکیده | ||
The effects of dietary nucleotide (NT) on growth performance and some haematological parameters of striped catfish (Pangasianodon hypophthalmus) were investigated. Different levels of the NT (0, 0.25, 0.5, 0.75, 1%) in the diet were used for 10 weeks starting on the fish weighted (1.52 ± 0.11 g). The results showed that NT supplementations did not improve final weight, weight gain, food conservation ratio as well as specific growth rates of striped catfish (P>0.05). Among all growth evaluated parameters, only the condition factor was significantly improved in fish fed on 0.75 and 1% of NT in comparison to control (P<0.05). There were no significant differences in hemoglobin, hematocrit, mean erythrocytic hemoglobin, mean erythrocytic volume, and mean erythrocytic hemoglobin concentration, white blood cell (WBC) counts and WBC/RBC ratio among fish fed on dietary nucleotide and control diet (P>0.05). However, some significant fluctuations were observed in the haematological parameters within groups of fish fed on different levels of NT (P<0.05). The results showed that feeding striped catfish with commercial NT had very limited effect on growth parameters and some haematological characteristics. | ||
