Title

EFFECT OF DIFFERENT DIETARY PROTEIN AND ENERGY LEVELS ON GROWTH OF JUVENILE BELUGA (HUSO HUSO)

Pages

  107-119

Abstract

 A 2×4 factorial design was conducted to study the effects of dietary PROTEIN and ENERGY levels on GROWTH performance of juvenile BELUGA (Huso huso) with average weight of 49.85±1.64 g. Experiments were conducted with two dietary PROTEIN levels (40 and 45%) and four dietary ENERGY level (18.5, 19.8, 21.1 and 22.4 MJ/kg diet) by ratio P/E (18.03 to 24.14 mg/kj). Fish were fed the experimental diets for 110 days. In each of the PROTEIN levels (40 and 45%), the feed efficiency, body weight increase, PROTEIN efficiency ratio, specific GROWTH rate, final body weight and total feed intake of fish improved significantly as dietary ENERGY levels increased (P£0.05). GROWTH of fish fed high- ENERGY diets was significantly higher than those of fish fed low- ENERGY diets at 40 and 45% dietary PROTEIN levels (P£0.05). PROTEIN content of carcass increased when dietary PROTEIN increased, but there was no significant different (P³0.05) between 40 and 45% PROTEIN. Lipid content of fish fed diet high- ENERGY level was significantly higher than those of fish fed low dietary ENERGY (P£.05). So the maximum GROWTH and weight (22.4±5.3 gr) was observed in treatment, that were fed diets containing 45% PROTEIN & 22.4 mega joule crude ENERGY. Considering that no significant difference were affected for among the diet for the parameters studied, the diet containing 40% PROTEIN, 21% fat and 21.1 mega Joule crude ENERGY per kilogram diet with a P/E ratio of 20 mg PROTEIN per kilo joule from a good quality source is a suitable diet in terms of physiology and economy can be considered a suitable diet to produce maximum GROWTH in juvenile BELUGA in the weight class 49 to 200g.
