Abstract
In this study, the effect of experimental diets containing different levels of carbohydrate and niacin on growth indices, carcass composition and hemolymph biochemical parameters of juvenile shrimp (Litopenaeus Vannamie) was investigated for 45 days. The mean initial weight of the shrimps was 5 ± 0.33 g which reared in 300 liter tanks with 8 treatments. Feeding was performed 4 times a day using experimental diets containing two levels of carbohydrate 15 and 30% and three levels of dietary niacin 100, 150 and 200 mg kg-1with two controls. At the end of the period, growth indices, carcass composition and biochemical indices of hemolymph of shrimps were assayed. The best growth performance consisted of the highest final weight (14.05 ± 0.5 g), final length (13.38 ± 0.05 cm) and specific growth rate (2.23 ± 0.07) was in  treatment contained 15% carbohydrate and 100 mg niacin kg-1 diet (P <0.05). Also, the highest glucose (53.66 ± 0.88 mg dL-1), HDL (27 ± 0.57 mg dl-1) and total protein values (10.9 ± 0.17 mg dl-1) was in  treatment contained 15% carbohydrate and 100 mg niacin kg-1 diet (P <0.05). On the other hand, the highest carcass protein content was observed in treatments containing 15% carbohydrate and 100-150 mg niacin kg-1 diet (P <0.05). Also, carcass fat decreased with decreasing dietary carbohydrate content (P <0.05). Therefore, the results showed that low carbohydrate level along with 100 mg niacin per kg of diet had a favorable effect on growth, carcass composition and health of young Vannamei shrimp.
