| Popis: | A feeding trial was conducted to evaluate the effects of nucleotide (NT) supplementation in diet on immune responses and disease resistance of juvenile hybrid tilapia, Oreochromis niloticus × Oreochromis aureus. Nucleotide was added at 0, 120, 240, 360, 480 and 600 mg NT/kg to low fish meal (6%) and high soybean meal (56%) basal diet for a total of 6 experimental diets. Each diet was fed to triplicate groups of tilapia (initial body weight 0.15 ± 0.005 g) in a recirculated freshwater rearing system for 10 weeks. Head kidney leukocyte superoxide anion production ratio was higher (P 80%) were observed in fish fed diets supplemented with NT than fish fed the NT unsupplemented control diet (56.7%). These results suggest that nucleotides supplemented at 120–240 mg NT/kg in diet enhances immune responses and survival of tilapia fed low fish meal and high soybean meal diet. |
