A 17-week feeding trial was carried out to evaluate theeffects of dietary L-carnitine level in beluga, Huso huso. Atotal of fish averaging 1247 ± 15.6 g (mean ± SD) wererandomly distributed into 21 fibreglass tanks, and each tankholding 10 fish was then randomly assigned to one of threereplicates of seven diets with 50, 150, 350, 650, 950 and1250 mg L-carnitine kg-1 diet or control diet (Biomar). At the end of 17 weeks offeeding trial, average weight gain (WG), feed efficiency (FE),protein efficiency ratio (PER) and condition factor (CF) offish fed 350 mg kg-1 diet were significantly (P < 0.05)higher than those of fish fed 50, 150, 950 and 1250 mg kg-1diets. WG, FE, PER and CF of beluga fed 650 mg kg-1dietor control diet (Biomar) were also significantly higher than those of fish fed 50, 950and 1250 mg kg-1 diets. Whole body and muscle proteinwere significantly improved by the elevation of dietaryL-carnitine level up to 350 mg kg-1. Liver superoxidedismutase and glutathione peroxidase activities of fish fed350 and 650 mg kg-1 diets were significantly higher thanthose of fish fed other diets. The dietaryL-carnitine level of 350mg kg-1 diet could improvegrowth performance, feed utilization, protein-sparing effectsof lipid, immune response, antioxidant defence system and reproductive success.
