The Effect of Dietary Nucleotides on Reproduction Indices, Hematological Indices of Rainbow Trout Broodstock (Oncorhynchus mykiss)
Abstract:
The roles of nucleotides and metabolites in fish diets have been sparingly studied for over 25 years. Beside possible involvement in diet palatability, fish feeding behavior and biosynthesis of non-essential amino acids, exogenous nucleotides have shown promise most recently as dietary supplements to enhance immunity and disease resistance of fish produced in aquaculture. This experiment was conducted to examine the effect of dietary nucleotides on Reproduction indices, hematological indices of rainbow trout broodstock. A basal diet supplemented with 0 (control), 1and 2 g nucleotide Kg-1 to formulate three experimental diets. 90 female rainbow trout were randomly divided into three experimental groups (30 fish per group) and were fed with one of the three experimental diets over four months prior to spawning. Broodstock fed with 2.0% of nucleotides, exhibited the highest absolute fecundity, gonad weight, white blood cell (WBC), red blood cell (RBC), lymphocytes (P>0.05). The results suggest that dietary nucleotides administration at 2 g Kg-1exerted positive effects on Reproduction indices, hematological indices of rainbow trout broodstock.
