Abstract: (24989 Views) |
| Effects of different levels of dietary nucleotides (NT) were studied on growth indices and body composition of rainbow trout with average weight of 11.35±0.32 during 8 weeks. This experimental was carried out in 700 L circular tanks with 40 fishes per tank. NT was added to the diet at a rate of 0.0, 0.05, 0.1, 0.15 and 0.2 percent. Fish were fed 5 times daily at a rate of 3-5% body weight per day. At the end of feeding trial, the fish fed 0.2% NT showed higher whole body protein, and lower lipid and ash levels compared to the control group. Administration of dietary NT at the level of 0.2% seems to positively influence the proximate composition of fingerling rainbow trout. |
