Abstract

To determine the effects of vitamin B3 on growth and body composition blood of children Sterliad (Acipenser ruthenus) are cultured and Breeding Centre and Shahid Beheshti restocking dam was barricaded. Six diets containing different amounts of vitamin B3 50,40,30,20,10,0 mg per kg of dry food to feed the fish for 8 weeks was considered of Sterliad. A total of 100 fish of sterliad with an average weight of 50 g to 18 fiberglass tub was introduced. The fish were fed daily at the rate of 5% of body weight. The results showed that the treatments in terms of weight, condition factor, growth rate and final length there were no significant differences (P>0.05) But no significant difference was observed in the daily growth (P<0.05). The biochemical composition (triglyceride, cholesterol, glucose, LDL, HDL and blood protein) in the treatments are significant differences (P<0.05). Based on the analysis of carcass significant differences between treatments in terms of moisture, fat, protein and ash seen significant (P<0.05). Maximum protein and ash and minimum fat was related to T3. According to the results we can say that vitamin niacin the significant effect on weight Sterliad no growth and reduce the fat and increase the body protein. As a result of the addition of 30 mg per kg of food vitamin niacin positive effect on the quality of its fish.
